OBJECTIVE:To observe clinical efficacy and ADR of Houttuynia cordata eye drops combined with Olopatadine eye drops in the treatment of allergic conjunctivitis. METHODS:160 eyes with allergic conjunctivitis were randomly divided into observation group and control group,with 80 eyes in each group. The control group was given olopatadine eye drops,and observa-tion group was additionally given H. cordata eye drops(medication interval>10 min)on the basis of control group. Both groups were treated for 14 days. Symptoms and signs of 2 groups were observed and scored before treatment and 14 d after treatment. Ef-fective rates of 2 groups were calculated,and the occurrance of ADR was observed. RESULTS:Compared with before treatment, symptoms and sings score of 2 groups were decreased,with statistical significance (P<0.01 or P<0.05);the decrease of two score in observation group were more significant than in control group,with statistical significance (P<0.05);effective rates of control group and observation group were 37.50%and 77.50%,with statistical significance(P<0.05). CONCLUSIONS:H. corda-ta eye drops combined with olopatadine eye drops can ameliorate clinical symptoms and signs of allergic conjunctivitis patients sig-nificantly,and improve therapeutic efficacies without obvious ADR.

Objective To investigate the value of cystic adenomatoid malformation volume ratio (CVR) using prenatal ultrasound in evaluation of congenital pulmonary sequestrations (PS) prognosis in fetus.Methods Totally 88 cases of fetal PS diagnosed with prenatal ultrasound were enrolled.The fetal CVR were recorded,and the clinical outcomes were observed.The fetus were further divided into CVR≥1.6 group and CVR＜1.6 group,then the fetal hydrops rate,incidence of respiratory distress symptoms after birth and perinatal infant survival rate between two groups were compared.Results In 88 cases,prenatal ultrasound diagnosed intralobar pulmonary sequestration (ILS) type in 62 cases (62/88,70.45％),extralobar pulmonary sequestration (ELS) type I in 19 cases (19/88,21.59％),and ELS type Ⅱ in 7 cases (7/88,7.95％).There were 81 (81/88,92.05％) live births,5 (5/88,5.68％) of induction,and 2 (2/88,2.27％) of intrauterine fetal death,respectively.In 44 cases of CVR≥1.6 group,36 cases (36/44,81.82％) had respiratory symptoms after birth,and 39 (39/44,88.64％) had combined fetal hydrops.The live birth rate was 84.09％ (37/44).In 44 cases of CVR＜1.6 group,3 cases (3/44,6.82％) had respiratory symptoms after birth and 3 (3/44,6.82％) had combined fetal hydrops.The live birth rate was 100％ (44/44).The fetal hydrops rate,incidence of respiratory symptoms after birth and perinatal infant survival rate were statistically different between the two groups (all P＜0.05).Conclusion Prenatal ultrasound CVR is an effective index for screening and assessing the prognosis in fetus with PS.

Objective To evaluate the feasibility of beside color Doppler ultrasound-guided popliteal vein catheter in treatment of lower extremity deep venous thrombosis (LEDVT).Methods Data of 50 patients with unilateral LEDVT were reviewed,including 25 cases underwent beside color Doppler ultrasound-guided catheter thrombolytic therapy (catheter thrombolytic group) and 25 cases underwent systemic thrombolysis and anticoagulant therapy (anticoagulant thrombolysis group).The cure rate,hospitalization time and the bilateral diameter differences were compared between the 2 groups.Results Thrombolytic effective rate was 100％ in both the 2 groups.Thirty patients were clinical cured,including 22 cases in catheter thrombolytic group and 8 cases in anticoagulant thrombolysis group.The cure rates were significantly different between the 2 groups (88.00％ [22/25] vs 32.00％ [8/25],x2 =16.333,P＜ 0.001).The hospitalization time of catheter thrombolytic group ([12.32 ± 1.49] days) was shorter than that of anticoagulant thrombolysis group ([16.44±2.95]days;t=-6.426,P＜0.001).The diameter differences between LEDVT side and contralateral side of the upper and lower 15 cm form knees in catheter thrombolytic group showed no statistical difference compared with anticoagulant thrombolysis group before the treatment (both P＞0.05),while of catheter thrombolytic group were smaller than those of anticoagulant thrombolysis group after the treatment (both P＜0.05).And the bilateral diameter differences before the treatment were larger than those after the treatment in both groups (all P ＜ 0.05).Conclusion Both of beside color Doppler ultrasound-guided catheter thrombolytic therapy and systemic thrombolysis and anticoagulant therapy can be used to treat LEDVT,while the efficacy of ultrasound-guided catheter thrombolytic therapy is better.

Objective: To explore prevalence of childhood neglect and autonomic nervous function, and its association in sixth graders students in Harbin, and to provide clues to improve physical and mental health of children and adolescents. Methods: Cluster sampling method was used to select 1 259 students from grade 6 in 5 schools in two districts of Harbin, and Childhood Trauma Questionnaire-Short Form (CTQ-SF) and TOHO University Medical Index (TMI) were filled in. Results: The total rate of childhood neglect was 45.7%, of which the rate of emotional neglect and physical neglect were 18.8%, 40.8%. The rate of autonomic nerves disorder was 47.2%. The rate of autonomic nerves disorder in students suffered from neglect, emotional neglect, physical neglect are higher than those without any of neglect(χ2=50.52, 32.02, 43.61, P<0.01), and with the increase of the degree of neglect, the rate of autonomic nervous disorder were gradually increasing(χ2=47.99, 47.07, 49.24, P<0.01). After controlled for gender, neglect, emotional neglect, physical neglect were positively associated with autonomic nerves disorder(OR=1.53-2.34, P<0.05), and the odd ratio for autonomic nerves disorder among those with mild-to-moderate,moderate-to-severe and extremely servere neglect was 1.37, 1.83, 5.10 compared to those with none or mild neglect. Conclusion Childhood neglect is closely related to adolescent the autonomic nerves disorder in sixth graders students in Harbin. Moreover, the more serious the childhood neglect is, the higher the detection rate of autonomic nerves disorder is. In order to improve the physical and mental health of children and adolescents, it is necessary to pay attention to childhood neglect and early assessment of their autonomic function.
