AIM:To study the clinical effect of silica gel drainage tube combined with lomefloxacin hydrochloride eye ophthalmic gel in the treatment of lacrimal duct obstruction.METHODS:Totally 86 cases (138 eyes) of lacrimal duct embolism treated in our hospital from February to December 2015 were divided into 43 cases (68 eyes) as control group and 43 cases (70 eyes) of the observation group according to whether they were treated with lomefloxacin hydrochloride eye ophthalmic gel.Patients in the control group were treated with silica gel drainage, while the observation group was treated with lomefloxacin hydrochloride eye ophthalmic gel on the basis of the control group.The total effective rate, serum hypersensitivity C-reactive protein (h-CRP) level, complications and recurrence rate were observed and compared between the two groups.RESULTS:The total effective rate in the patients with obstructive nasolacrimal duct, common lacrimal duct obstruction, and lacrimal duct obstruction in observation group were 95.2%, 100.0%, 96.7%, higher than those in control group (P<0.05).There was no significant difference between the two groups in preoperative serum h-CRP levels (P>0.05).The serum levels of h-CRP in patients in the observation group at 3d and 7d after operation respectively were 2.40±0.84g/mL, 1.94±0.84g/mL, lower than those of control group at the same time (P<0.05).The complication rate of the observation group was 1.4%, which was lower than that of the control group (P<0.05).Follow up for 6-18mo, the recurrence rate was 11.4% in the observation group, which was significantly lower than the control group (P<0.05).CONCLUSION:The combination of silica gel drainage tube and lomefloxacin hydrochloride eye ophthalmic gel in the treatment of obstruction of lacrimal duct has good clinical efficacy, low inflammatory reaction, low complication rate and low recurrence rate.

Objective To explore the efficacy and safety of high-dose methotrexate (MTX) and L-asparaginase (L-Asp) for the treatment of adult patients with high risk Ph acute lymphoblastic leukemia (ALL).Methods Five adult patients with high risk Ph-ALL were treated with several courses of MTX (3-5 g/m2 by continually intravenous drip for 24 h) and L-Asp (8 000-10 000 U/time, once a day, 10 times for one cycle).Results Five patients were disease-free survival, their survival time was 60-96 months and the median survival time was 73 months.The chemotherapy-related bone marrow depression was mild.No obvious liver and kidney damage, severe allergic reaction and pancreatitis were observed.Conclusion Highdose MTX and L-Asp are effective and well tolerated, and may contribute to long-term survival of adult patients with high risk Ph-ALL.

Objective To quantify the neurons in the temporal lobe white matter and find their distribution in the neurologically normal individuals.Methods The temporal lobe at the level of exterior geniculata body from brain autopsy samples of 14 neurologically normal individuals were made into large slice followed by quantitative analysis of neuron density,cell density,ratio and diameter of the neuronal nuclear and the distribution of white matter neurons using two-dimensional cell counting methods.Results With the depth of the white matter of the temporal lobe increasing,the neuron density decreased from 29.26 neurons/ mm~2 to 7.32 neurons/mm~2 and 0.00 neurons/mm~2,respectively;the cell density,neuron ratio and diameter of the neuronal nuclei all decreased.Conclusion There are neurons in the temporal lobe white matter of neurologically normal individuals,whose distribution of neurons is related to the depth of white matter.

Objective To investigate the epidemic characteristics of mycoplasmal pneumonia outbreak in a middle school, and to provide suggestions for outbreak prevention and control.Methods Principle and method of field epidemiology was used and,speciously,questionnaire investigation was carried out for the outbreak of mycoplasmal pneumonia.Outbreak characteristics and corresponding emergency intervention were discussed.Results There was an outbreak of mycoplasmal pneumonia in 2 classes of the middle school,and the attack rate was 42.50%.The attack rate of other classes was 6.75%.Timely identification and diagnosis of the disease,and comprehensive control to prevent the spread of the epidemic,brought the disease under control.Conclusion The outbreak of mycoplasmal pneumoniae infection is associated with the close contact in daily activities.Emergency intervention can prevent the further spread of the disease.

Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.

Objective:Clonidine,by activating peripheral α-sbrenoceptors, produces transient pressor response after i.v.injection in anesthetized animals.Moxonidine, with at least 40-fold higher affinity to I1-imidazoline receptors than to α2-adrenoceptors,produces also a transient pressor response. This work was designed to investigate whether I1-imidazoline receptors are involved in this pressor effect of moxonidine. Methods:Female spontaneously hypertensive rats(SHRs,aged 14-16 weeks)were anesthetized with urethane.To observe the transient pressor responses,moxonidine 0.1,0.3,1.0mg/kg(intravenous,i.v),2.0μg(intracerebroventricular,i.c.v.)and 1.0,10.0mg/kg(intragastric,i.g.)were administrated in different groups of rats.To evaluate the roles of α1-adrenoceptors,α2-adrenoceptors and I1-imidazoline receptors in the transient pressor responses to moxonidine, prazosin(10.0μg/kg),yohimbine(2.0mg/kg),phentolamine(0.2mg/kg),idazoxan(1.0mg/kg)or yohimbine+idazoxan(2.0mg/kg+1.0mg/kg)were intravenously given to the animals before moxonidine 0.3mg/kg (i.v.).Results:It was found that i.v.moxonidine produced a greater pressor response than clonidine when producing a similar reduction of blood pressure.This effect of moxonidine was not influenced by prazosin, but was partly inhibited by yohimbine, phentolamine or idazoxan,and completely blocked by the combination of yohimbine and idzaxon.Neither i.c.v.injection nor i.g. administration of moxonidine induced transient pressor responses.Conclusion:The transient pressor response of i.v. moxonidine is mediated by both peripheral I1-imidazoline receptors and α2-adrenoceptors.
