ObjectiveTo observe the intraoperative techniques of artificial nasolacrimal duct and evaluate the effectiveness.MethodForty-nine cases(56 eyes) ofchronic dacryocystitis underwent artificial nasolacrimal duct placement.The artificial nasolacrimal duct was dilated and the stent was retrogradely placed.Dacryocystography was performed before operation.ResultsArtificial nasolacrimal duct placement was technically successful in 53 eyes(94.64％),improvement rate was 3.57 ％ (2/56).The total effective rate was 98.21％(55/56) after operation.ConclusionInterventional artificial nasolacrimal duct placement is a safe,simple and effective method for the treatment of chronic dacryocystitis.

Objective: To investigate the effect of different concentrations of dextrose transfusion on cerebral glucose metabolism in pediatric neurosurgical operations. Methods: Sixty anesthetized children undergoing selective cerebral tumor resection were randomly divided into three groups: Ringer lactate solution group (A, n = 20), 2.5% dextrose lactated Ringer's solution group(B, n = 20), 1% dextrose lactated Ringer's solution group (C, n = 20). All the hemodynamic data were recorded during anesthesia. The values of blood glucose and lactic acid were collected before intubation(T_a), 2 hours after opening cerebral dura mater (T_b) and the end of operation (T_c). The catheters for microdialysis were punctured into normal brain tissue. The contents of glucose and lactic acid were determined in the collected intercellular fluid by biochemical analysis instruments at T_A and T_B respectively. Results: There were no differences in heart rate(HR), mean arterial pressure(MAP) and arterial oxygen saturation (SpO_2) among three groups(P > 0.05). There were no differences in blood glucose at T_a between three groups(P > 0.05). The values of blood glucose at T_b and T_c were B group＞C group＞A group(P < 0.05). The values of blood glucose were higher at T_b and T_c than that of T_a in three groups(P < 0.05). There were no differences in blood lactic acid among three groups(P > 0.05). There were no significant differences in values of glucose and lactic acid in the collected intercellular fluid among three groups(P > 0.05). Conclusion: Transfusion of Ringer lactate solution or low concentration dextrose solution will increase blood glucose in pediatric neurosurgical operations, but still in the normal range, which has a little influence on blood lactic acid, glucose and lactic acid in brain intercellular fluid. It is a safe choice during neurosurgical operation.

Objective To investigate the association of single nuchotide polymorphism (SNP) + 45 T/G and + 276 G/T in the adiponectin gene with type 2 diabetes in Guangxi Zhuang pregnant women.Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to determine the distributions of allele and genotype frequencies of SNP + 45T/G polymorphism and SNP + 276 G/T polymorphism in adiponect in gene in 98 type 2 diabetic patients and 135 normal control subjects.Results The TG,GG genotype frequencies of the SNP +45T/G were higher in gestational diabetes mellitus (GDM) than those in controls (P ＜ 0.05).The G-allele frequency was significantly higher than those in controls (P ＜ 0.05).The distribution of genotype and allele frequencies of the SNP + 276 G/T polymorphism was not different in diabetes and control groups (P ＞ 0.05).Women carrying the TG and GG allele of SNP +45T/G showed higher TG (P ＜0.05),and lower APN levels than those with TT genotype (P ＜0.05).Conclusions G allele of SNP +45T/G was related to GDM possibly.T→G variation might involve in the occurrence of GDM by reducing serum diponectin levels.Monitoring this site in pregnant women could predict the risk of GDM.

Coptis chinensis, a traditional Chinese medicine, has been found to have multiple pharmacological effects recently. Some research showed that C. chinensis has antioxidant effects, including scavenging oxygen free radicals, alleviating lipid peroxidation, enhancing activity of antioxidant enzymes, et al. C. chinensis may inhibit several classical pathological pathways in diabetes. C. chinensis is a potential medicine to prevent and treat diabetes mellitus and its complications. This review focuses on the recent research progress in the study of antioxidant effects of C. chinensis and its major contributions to diabetes treatment/therapy.

ObjectiveTo assess the degree of pain in elderly patients with mechanical ventilation in ICU using critical-care pain observation tool(CPOT) and to choose the correct sedative and analgesic method.Methods 110 elderly patients in ICU after neurosurgery were divided into three assessment stages,every stage had two record points and total six points (T1-T6):the first stage (intubation and unconsciousness,T1-T2),the second stage (intubation and consciousness,T3T4 ) and the third stage(extubation and consciousness,T5-T6 ).Among them T1,T3and T5were nonnocuity assessment points of every stage,while T2,T4 and T6 were nocuity assessment points of every stage.The assessment time was one minute at every point.After recorded at every point in second and third stages,patients were asked to use the pain intensity descriptive scale (PIDS) themselves.CPOT,heart rate and mean arterial pressure (MAP) from T1 to T6 were recorded as well as PIDS from T3 to T6 in second and third stages.Results In the three stages,CPOT〔(26.8 vs.0.54,3.36 vs.1.20,2.78 vs.0.68) scores〕,HR〔(95 vs.85,94 vs.82,94 vs.84)beat/min〕 and MAP〔(95 vs.85,95 vs.87,94 vs.87)mm Hg〕 at T2,T4and T6 were higher than T1 (t=-42.89,-55.95,-55.38),T3 (t =- 5.52,- 11.33,- 11.78) and T5 ( t =- 5.54,- 9.95,- 11.33 ) ( P＜ 0.05 ).The PIDS at T4 and T6were higher than at T3and T5in the second and third stages 〔(2.52 vs.1.69,2.12 vs.1.44)scores〕 (P＜0.05).The correlation coefficient between CPOT and PIDS at T3 and T4 in the second stage were 0.49 and 0.58,respectively (P＜0.05),and between CPOT and PIDS at T5 and T6 were 0.52 and 0.59 in the third stage,respectively (P ＜ 0.05),and they both reached moderate correlation.ConclusionsCPOT may be an effective way to assess the degree of pain in elderly patients with mechanical ventilation at present.

Objective To compare the healing effect of compound tibial and fibular fractures with two different fixation methods of external fixators (EF) and interlocking intramedullary nail ( INF). Methods Eighty-six cases of compound tibial and fibular fractures received different treatment, 36 cases in EF group and 50 cases in INF group. The difference between two groups was statistically analyzed according to WU Yue-song and XU Bo-cheng standard and Johner-Wruh score. Results All cases were followedup for 6-24 months,average (16.0 ± 2.4) months. The excellent and good rate were 80.6% (29/36) in EF group and 88.0%(44/50) in INF group respectively. There was no significant difference between two groups (Z =-1.103,P ＞0.05). Conclusions To the compound tibial and fibular fractures patients,INF can be considered as an effective method. It's an important therapy choice with EF to heal the compound tibial and fibular fractures.
