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 effect of upper limb pillow position on hemodynamic and safety of patients undergoing cerebellopontine angle tumor resection.Methods:Eighty-four patients receiving cerebellopontine angle tumor resection in our hospital from January 2016 to December 2019 were randomly divided into the experimental group (42 cases) and the control group (42 cases). Patients in the control group were placed in routine upper limb position, while patients in the experimental group were placed in upper limb pillow position. The data including systolic pressure, diastolic pressure, heart rate, saturation of blood oxygen were recorded on admission of operation room, completing placing body position, 30 minutes and 60 minutes after operation and after finishing the operation. The numbness/soreness of upper limbs and pressure injury rate was compared between the experimental group and the control group.Results:The rate of numbness/soreness of upper limbs were 2.4% (1/42) in the experimental group, 19.1%(8/42) in the control group, the differences were statistically significant ( χ2 value was 6.098, P<0.05). The stage 1 pressure injury were 2 cases in the experimental group, stage 1 and 2 pressure injury were 6 cases and 2 cases, respectively in the control group, the differences were statically significant ( Z value was 2.039, P<0.05). Conclusion:Upper limb pillow position of the operation side can reduce postoperative complication of patients undergoing cerebellopontine angle tumor resection, but will not increase the risk of abnormal hemodynamic fluctuation.

Objective To explore the similarities and differences in endoscopic and pathological characteristics between elderly and non-elderly patients with Barrett esophagus (BE). Methods Three hundred and seventy-one cases with BE were divided into elderly group (n=254) and nonelderly group (n=117). The detection rate, endoscopic findings and pathological changes were assessed. Results The detection rate of BE was 2.9% in the elderly, and 0. 9% in the non-elderly(χ2 =127.8, P＜0.01). The 112 cases (44.1%) of the elderly had reflux symptoms, and so did 87cases (66.7%) of the non-elderly (χ2 =55.9, P＜0.01). The detection rate of BE in the two groups was increased year by year from 2004 to 2008. The detection rate of ring pattern was significantly higher in elderly group than in non-elderly group (28.7% vs. 10.3%, χ2=14.5, P＜0.01). Nonelderly patients had higher rate of island pattern than elderly patients (59.5% vs. 71.7%, χ2=4.7,P＜0.05). There were significant differences in the rate of specialized intestinal metaplasia between elderly and non-elderly patients (42.1% vs. 27.4%, χ2=6.9, P＜0.01). The difference in low and medium grade intraepithelial neoplasm between the two groups had statistical significance (21.3% vs.11.1%, χ2=4.9, P＜0.05). There were two cases with adenocarcinoma in elderly group, but no case was found in non-elderly group. The detection rate of H. pylori was comparable between elderly group and non-elderly group (35.5% vs. 40.9%, χ2=0.40, P＞0.05). Conclusions The elderly patients have the 3.2 times higher detection rate of BE than non-elderly patients. The detection rates of specialized intestinal metaplasia and intraepithelial neoplasm are higher in elderly group than in nonelderly group.

Objective To reconstruct sparse views CT image based on defective projection data.Methods The position of bad bins in detector determined whether the linear interpolation was applied to the defective projection data.Moreover,reconstruction of air pixels in CT image was achieved rapidly and accurately.Results he experimental results showed that the proposed method could solve the problem from classical ART-TV method that the robustness was unstable due to the different positions of bad bin in CT detector.Conclusion Compared to analytical reconstruction methods,iterative methods can solve the reconstruction problems in this modality so that the radiologist is facilitated to perform image processing and quantitative analysis.

Objective To evaluate the effect of Ganoderma lucidum on drug resistance of the cisplantin-resistant ovarian cancer cell line(A2780CP).Methods The A2780CP cells were randomly divided into control group and test group.The cells in control group and test group were incubated in culture media alone and in culture media containing Ganoderma lucidum 0.5 mg/ml for 48 h respectively.The resistance index(RI) of A2780CP was determined by WST-1 assay.The expression of Akt,Bcl-2 and p53 protein was measured by Western blot.Results The RI was significantly deeressed,the expression of Akt and Bcl-2 protein was down-regulated,while p53 protein expression was up-regulated in test group as compared with control group(P<0.05).Conclusion Ganoderma lueidum can reduce the resistance of A2780 CP cells to cisplantin by down-regulating the expression of Akt and Bcl-2 and up-regulating p53 expression in A2780CP cells.

Objective To investigate the inhibition effects of c erbB 2 and c raf 1 antisense oligodeoxynucleotides (ASODN) combined transfection on the human ovarian epithelial cancer transplanted subcutaneously in nude mice Methods There were 7 groups: normal control group,c erbB 2 sense observed group,c raf 1 sense observed group,c erbB 2 antisense observed group,c raf 1 antisense observed group,whole dose combined group,half dose combined group Human ovarian epithelial cancer cells SKOV3 were treated by different oligodeoxynucleotides,then transplanted subcutaneously in nude mice,respectively The changes of tumor volume were observed and the tumor growth inhibitory rate was calculated Results There was no difference between sense observed group and normal control group There was a larger growth inhibitory rate in whole dose combined group and half dose combined group,the first time that can be detected was 13 7 days and 15 2 days,and the maximum tumor growth inhibitory rates were 61 1% and 71 3%,respectively Conclusions The results suggested that ASODN combined transfection can inhibit the tumorigenesis of ovarian epithelial cancer cells in nude mice,it may be a more useful gene therapy for the ovarian epithelial carcinoma

Objective To observe the effects of anisodamine on levels of neurotensin in the plasma and lung homogenate during acute lung injury in rats after brain trauma.Methods The level of neurotensin in the plasma and lung organizes after brain trauma and that after administration with anisodamine were determined by radioimmunoassay(RIA).Results Level of neurotensin in the plasma and lung homogenate of rat with brain trauma was obviously higher than that in normal control group but significantly lower than that in anisodamine group.Conclusion Increase of neurotensin in the plasma and lung homogenate may be due to causing lung injury after brain trauma.Anisodamine can exert protective effect on acute brain injury by reducing level of neurotensin in in the plasma and lung homogenate.

Objective To explore the relationship between parental authority,parental psychological control, parental attachment and medical students' social anxiety, and to provide theoretical guidance for medical students' mental health.Methods 2105 medical students were assessed with the social phobia inventory (SPIN), Parental authority questionnaire (PAQ), Parental psychological control questionnaire, Inventory of parent attachment (IPA).Results The mean SPIN score of social anxiety was 17.75 ± 10.47.Girls scored higher than boys,but there were no statistically significant differences between them( 17.97±10.44 vs 17.29 ± 10.52, t =1.305, P=0.192).Rural medical students scored higher than urban students,and the difference had statistical significance (19.47 ± 10.60 vs 15.85 ± 10.01, t = 7.478, P ＜ 0.01 ).Stepwise regression revealed that, for urban students' anxiety, father communication and mother authoritative/flexible were protective factors, father unconscionable emotional response, mother alienation, father unconscionable viewpoint and mother communication were risk factors; and for rural students' anxiety father communication was protective factor, mother alienation and mother authoritarian were risk factors.Conclusion Factors such as parental authority, parental psychological control and parental attachment will affect medical students' social anxiety.But the factors are not same between urban and rural.So these factors are considered when carrying out health education for parents.

Objective:To evaluate the efficacy of chemotherapy for advanced biliary tract carcinoma and the factors that influence sur-vival. Methods:A total of 91 cases of advanced biliary tract carcinoma from January 2010 to April 2015 were enrolled in our study. The patients' characteristics, chemotherapy regimens, and effects were analyzed. Results:We enrolled 56 males and 35 females with a me-dian age of 57 years. A total of 90 patients were assessable for their responses to first-line chemotherapy. A total of 69 patients re-ceived the GP regimen, whereas 21 patients received some other regimens. The disease control rate (DCR), median progression free survival (mPFS), and median overall survival (mOS) were 68.1%versus 52.4%, 5.10 months versus 2.50 months (P=0.025), and 13.00 months versus 7.20 months, respectively. Only 31 patients received S-1 based regimens, and 12 patients received some other regi-mens as second-line chemotherapy. The DCR, median PFS, and median OS showed no statistical differences. Only four patients re-ceived S-1 based regimen plus bevacizumab as second-line chemotherapy (median PFS 5.3 months;median OS 7 months). Hematologi-call toxicity was the most common side effect in the first-line GP regimen. The side effects of the S-1 based chemotherapy regimen was relatively less. Conclusion:The GP regimen is an effective first-line chemotherapy for advanced biliary tract carcinoma, whereas S-1 ap-pears as an effective second-line chemotherapy drug. Bevacizumab-based regimens may be effective and require further validation.
