Objective To observe the influence of rational emotional therapy on breast cancer patients preoperation. Methods 50 cases of breast cancer patients were randomly divided into the experimental group and the control group with 25 cases in each group. The control group was provided routine therapy and nursing, health education and general psychological nursing, based upon these routine measures, the experimental group adopted systematic and standardized rational emotional therapy. Zung self rating depression scale(SDS), Zung self rating anxiety scale(SAS), Pittsburgh Sleep Quality Index scale(PSQI)were used to evaluate the effect between two groups. Results No significant differ-ence existed in anxiety, depression and sleep quality between the two groups at admission, but significant difference was seen one day preoperation, also there was statistical significance between at admission and one day preoperation in the experimental group. Conclusions Rational emotional therapy of breast can-cer patients who underwent surgical operation played a significant role on their preoperative short-term e-motions(including anxiety,depression, sleep quality), and worthy of clinical application.

Objective To discuss the effect of psychological intervention on prevention of posloperation infection in patients with breast cancer .Methods 336 patients with breast cancer after operation were divided into the control group and the intervention group with 168 cases in each group.The control group received routine nursing while the intervention group Was given psychological intervention based upon routine nursing.The incidence of postopemtion infection was observed in the two groups.Results Incidenc of infection took place in 27 patients(8.04%)among 336 cases.The incidence rate infection in the control group was 12.50%,which was evidently higher than that of the intervention group(3.57%),x2=9.06,P＜0.01.The infection location and time in the intervention group was better than that of the control group.Conclusion Psychological intervention could reduce the incidence rate of posteperation infection in patients with breast cancer.

OBJECTIVE:To investigate the effects and mechanism of total flavonoids from Armeniaca mume on depression in chronic stress depression model rats. METHODS:60 rats were randomly divided into normal saline group,model group,fluox-etine group(positive control,20 mg/kg)and total flavonoids from A. mume low-dose,medium-dose,high-dose groups(80,160, 240 mg/kg), 10 in each group. Except for normal saline group, the other groups adopted chronic unpredictable mild stress (CUMS)+solitary feeding condition to induce depression model. These groups were intragastrically administered,once a day,for 28 d. Changes of body mass and food intake,degree of preference for sugar were observed;forced swimming test and tail suspen-sion test were used to determine the time that rats did not move;open field test was used to determine the changes of residence time in central square,horizontal crossing lattice,standing times,modification times;tumor necrosis factor α(TNF-α),cortisol, interleukin 6 (IL-6),serotonin (5-HT) levels in serum after 24 h of last administration were determined. RESULTS:Compared with normal saline group,growth of body mass,food intake and sugar preference percentage in model group were decreased;the time that rats did not move was prolonged in forced swimming test and tail suspension test;residence time in central square was prolonged,while horizontal crossing lattice,standing times and modification times were decreased in open field test;serum levels of TNF-α,cortisol were increased,while IL-6,5-HT were decreased,with statistical significances (P<0.05 or P<0.01). Com-pared with model group,except that there were no obvious improvement in sugar preference percentage,the time that rats did not move in forced swimming test,modification times in open field test in total flavonoids from A. mume low-dose group and IL-6, 5-HT levels in serum in total flavonoids from A. mume low-dose,medium-dose groups,the above-mentioned indexes were obvious-ly improved in other groups (P<0.05 or P<0.01). CONCLUSIONS:Total flavonoids from A. mume can obviously improve the CUMS-induced depression in rats,and the mechanism may be related to inhibiting inflammation response,adjusting the hypothala-mus-pituitary-adrenal axis functions.

AIM:To observe the expression of TLR2 and TLR4 on mast cells (MCs) in the periapical tissues from different types of human chronic periapical diseases , and to analyze the role of TLR 2 and TLR4 on tryptase-positive MCs in the immunopathogenesis of human chronic periapical diseases .METHODS: A total of 60 donors, including healthy control group , periapical granuloma group and periapical cyst group , were enrolled in the study .The periapical tis-sue specimens were fixed in 10%buffered formalin and stained with hematoxylin and eosin for histopathology , or stained with double-immunofluorescence for identification of TLR 2-tryptase and TLR4-tryptase double-positive MCs in the periapical tissues.RESULTS:Compared with the healthy control , the densities of TLR2-tryptase and TLR4-tryptase double-positive MCs in periapical tissues were significantly increased in human chronic periapical diseases (P<0.01).The densities of TLR2-tryptase and TLR4-tryptase double-positive MCs in periapical cyst group were significantly higher than those in peria-pical granuloma group (P<0.01).CONCLUSION:TLR2 and TLR4 were expressed on the MCs in the periapical tissues of human chronic periapical diseases .TLR2-tryptase and TLR4-tryptase double-positive MCs may participate in the patho-genesis of chronic periapical diseases .

A novel flow-injection chemiluminescence (FI-CL) method free of CL reagent was developed for the determination of captopril based on its enhancing effect on the CL derived from diperiodatoargentate(III)-sulfuric acid system. Compared with the conventional CL system, the CL system based on trivalent silver was characterized of good selectivity for the absence of CL reagent. The CL mechanism was discussed through CL spectra and UV–vis absorption spectra. The conditions of the FI-CL system were investigated and optimized. Under the optimal conditions, the relative CL intensity was linear with the captopril concentration in the range of 0.3–15.0 μg/mL. The detection limit for captopril was 0.05 μg/mL, and the relative standard deviation (n=11) was 2.0% for 5.0 μg/mL captopril. The proposed method was applied to the analysis of captopril in tablet and human urine with the recoveries of 83.1%–112.5%, and the relative standard deviations of 0.5%–4.4%. The results obtained by the proposed method agreed well with those obtained from HPLC method. The proposed method is fast, convenient, and cost-effective for the determination of captopril in medicine and biological samples.

Objective To explore the effect of rational emotive therapy on self-esteem status of breast cancer patients.Methods 118 cases of breast cancer patients were randomly divided into the control group and the observation group with 59 cases in each group.The control group received routine care,and the observation group received rational emotive therapy on the basis of routine care.The self-esteem status of the two groups of patients was assessed before and after the intervention respectively with State Self-Esteem Scale (SSES).Results The score of behavior self-esteem,social self-esteem,appearance self-esteem and the total score of self-esteem of the patients in two groups before intervention showed no significant difference,but the above scores were higher in the observation group than those in the control group after intervention.Conclusions Rational emotive therapy can improve self-esteem status of breast cancer patients,thereby improve the mental health of the patients.

Objective:To analyze the epidemiological and clinical characteristics of hospitalized patients with dengue fever in Guangdong Province in 2019, so as to provide reference for clinical diagnosis and treatment of dengue fever.Methods:The general data, laboratory examination data, clinical manifestations and prognosis data of 480 inpatients with dengue fever admitted to Eight People′s Hospital Affiliated to Guangzhou Medical University between January 4 and October 31, 2019 were analyzed retrospectively. The clinical and onset characteristics of patients with dengue fever were described.Results:Among 480 dengue patients, 442(92.1%) were dengue fever, 38(7.9%) were severe dengue, and 136(28.3%) had underlying diseases. The peak age of onset was mainly in young adults aged 20 to 49 years old, accounting for 66.0%(317/480) in total. The seasonal peak was mainly in August to October. There were 399(83.1%) local cases and 61(12.7%) imported cases. The most common clinical manifestations were fever (98.1%, 471/480), chills (72.9%, 350/480), headache (58.5%, 281/480) and bone/joint/muscle pain (67.1%, 322/480), followed by digestive tract symptoms and respiratory tract symptoms. Among 446 serum samples, 358 (80.3%) were dengue virus (DENV)-1, 54 (12.1%) were DENV-2, 34 (7.6%) were DENV-3. The main laboratory tests of the patients were leucopenia (65.8%, 316/480), low hematocrit (30.2%, 145/480), thrombocytopenia (48.3%, 232/480), neutropenia (44.8%, 215/480), elevated alanine aminotransferase (ALT) (37.7%, 181/480) and aspartate aminotransferase (AST) (59.4%, 285/480). Treatment mainly adopted symptomatic support treatment and active prevention of complications. The length of stay was (5.8±3.1) days (range 1.0-38.0 days). A total of 461(96.0%) patients were cured or improved.Conclusions:In 2019, the majority of dengue fever patients in Guangdong Province are young adults aged 20 to 49 years old, and the proportion of severe patients is high, with DENV-1 infection as the main type. After symptomatic support treatment and active prevention of complications, most of the dengue fever patients have a good prognosis.

Malaria is one of the major diseases threatening the lives of people in Africa. Over the past decade, China has provided anti-malaria assistance to Africa. In November 2007, fast control malaria team of Guangzhou University of Chinese Medicine cooperated with the Comoros health authority. In Moheli Island of the Comoros, the anti-malaria team adopted a new strategy of Mass Drug Administration (MDA) and active intervention. They established an effective anti-malaria system and reporting system, as well as a local anti-malaria team. Furthermore, they treated patients with malaria in Moheli Island and implemended health education in local people. In a very short time, they have achieved remarkable results. This paper summarized the experiences of the project in order to provide useful reference for China to better carry out anti-malaria action in Africa and expand foreign health assistance.
