Objective To investigate of the clinical effects of the combined use of all-trans retinoic acid compound and capsule of total glucosideof paeony on reticular oral lichen planus.Methods A total of 120 patients were randomly divided into 3 groups:experimental group (group E),control group 1 (group C1),and control group 2 (group C2).Topical application of alltrans-tretioin compound and systematic administration of capsule of total glucosides of paeony were applied in group E.The group C1 only received topical application of alltrans-tretioin compound and the group C2 only took oral administration of capsule of total glucosides of paeony.The clinical effects were evaluated 3 months and 6 months after application of these medicines.The clinical results were followed up for 6 months.Results A total of 107 patients completed the follow-up.The total effective rates were 78％ (29/37),75％ (27/36) and 56％ (19/34) in group E,C1,and C2 respectively after the administrations for 3 months.There was significant difference between group E and group C2 (x2 =4.094,P =0.043).No significant difference between group E and group C1 was found (x2 =0.117,P =0.733).After 6 months,the total effective rate of group E(86％) was significantly higher than that of group C1 (64％) (x2 =4.303,P =0.038) or C2 (62％) (x2 =5.722,P =0.017).Conclusions The combined application of topical all-trans retinoic acid compound and capsule of total glucosideof paeony could improve the clinical symptoms of reticular oral lichen planus.

5' nucleotides (5'NT), a purine degradative enzyme, is capable of hydrolyzing nucleotide and acting as a phosphotransferase simultaneously. It has critical role in maintaining nucleotide metabolism balance. The present study was aimed to investigate the expression of 5'NT in bone marrow granulocytes (BMGs) from patients with acute myeloid leukemia (AML) and healthy donors comparatively. The BMGs were isolated from bone marrow of 33 patients with AML and 6 healthy donors by using lymphocyte isolating solution. The reactivity of 5'NT was detected by electron microscope and cytochemistry of cytidine monophosphate (CMP). The positive BMG ratio and their index were calculated on the base of ultrastructural observation semiquantitatively. The results indicated that electron microscopy revealed plasma membrane reacting pattern of CMP. Most BMGs from normal donors were CMP negative or exhibited lower active degree. All cases of M(0), M(1), M(2) and t (8; 21) showed high positive percentages and high indexes of BMGs, but no statistic differences between them. APL of t (15; 17) shared lower percentages and indexes than other subtypes. There was no significant difference between APL and normal donors statistically. In conclusions, the results suggested the expression of 5'NT may be associated with BMG differentiation in AML, and APL of t (15; 17) may be a highly differentiated leukemia subtype.

OBJECTIVETo investigate the impact of intracellular acidification (IA) on drug resistance of leukemia cells with high P-glycoprotein (P-gp) expression, and to provide a new method for the reversing of multidrug resistance (MDR).

METHODSReal-time PCR was used to determine the expression level of mdr1 gene, and the leukemia cells with high P-gp expression were selected. The specific inhibitor of Na+/H+ exchanger 1 and the "high K+" buffer were used to acidify the cells, and the confocal laser microscopy was used to determine the intracellular pH (pHi) and effect of IA on the accumulation of doxorubicin. The MTT method was used to determine the effect of IA on the cell viability. The flow cytometry was used to detect the effect of IA on the P-gp function, and Western blotting was used to determine the effect of IA on the expression of P-gp.

RESULTSThe pHi was decreased to 7.0, and compared with that of control the mdr1 mRNA expression was decreased to (53.2+/-11.0)% after 1 h, and to (16.6+/-7.0)% after 3 h treatment. The P-gp expression was decreased to (56.0+/-9.0)% of the control after 3 h treatment. The accumulation of Rh123 was 71.03+/-0.47 at pHi 7.0, which was increased obviously as compared to the control group 20.07+/-0.39. The increased accumulation of doxorubicin was also observed by confocal laser microscopy.

CONCLUSIONThe expression and function of P-gp on the patients cells are inhibited by IA.

OBJECTIVETo investigate the occupational stressors and modifiers of pediatricians and nurses in order to find the measurements for control of the job stress.

METHODS427 pediatricians and nurses working in five hospitals of a city served as subjects. Of them, the staff in section of pharmacy and toll offices in each hospital mentioned above served as control group. The General Job Stress Questionnaire was used to investigate the job stress by self-assessment.

RESULTSThe scores of job demand, job risk, drug using, daily job stress, positive feelings, patient A behavior, physical environment and feeling balance in pediatricians and nurses were higher than those of control group, but the scores of job-person conflict, environmental control, technology utility, mental health, responsibility on things were lower than those of control group (P<0.05). The points of job future, job locus of control, self-esteem, job satisfaction, job load variance, depression in nurses were higher than those of pediatricians, and non-work activities, job risk and daily life stress were lower than those of doctors (P<0.05). The main affecting factors on job strain of pediatric staff included job monotony, higher job demand, more non-work job, lower job control, more job risk, job future ambiguous, poorer social support, lower job locus control and lower self-esteem.

CONCLUSIONThe stress degree of pediatric staff is higher than that of controls. The pediatricians have more job stress than that of nurses. The main stressors of pediatric staff are job monotony, higher job demand, more non-worker activity, lower job control, higher job risk and ambiguous job future. The main modifiers are good social support, external job locus of control and higher self-esteem.

OBJECTIVETo discuss the diagnosis and treatment of primary hepatic carcinoid tumor (PHCT).

METHODSReport one case of huge PHCT treated in February 2004, and search the other 19 cases which were published from January 1994 to December 2006 in the Chinese biological and medical literature database. The clinical manifestation, pathological findings, diagnosis and treatment of these 20 PHCT patients were analyzed retrospectively.

RESULTSThe main symptoms were abdominal pain or discomfort (8 cases) and abdominal mass (7 cases), cases with typical carcinoid syndrome were rare (3 cases). Immunohistochemical staining was positive for neuron-specific enolase, chromogranin A and synaptophysin in most cases. Sixteen cases received operation, among which there were 13 removed completely, other 4 cases were treated by transcatheter arterial chemoembolization (TACE).

CONCLUSIONSThe definite diagnosis of PHCT depends on pathological and histochemical findings. Complete surgical resection is the best treatment for PHCT with favourable prognosis. TACE is also effective for nonoperative cases.

This review aims to interpret the interventions to improve physical function for children and young people with cerebral palsy, thus providing relevant suggestions.Relevant literatures published before November 2018 were systematically searched in Cochrane library, CINAHL, and Embase MEDLINE using the Grading of Recommendations Assessment, Development and Evaluation method.Consult with international experts and patients to assess evidence and recommend it.Based on 3 systematic reviews, 30 randomized clinical trials, and 5 pre-and post-treatment studies, a total of 13 recommendations were given.The guidelines recommend that, in order to achieve functional stan-dards, intervention measures should include, patient-selected goals, full-task practice in real-life settings, support for family empowerment, and a team approach.The age, ability, and child/family preferences were all needed to be considered.In order to improve walking ability, ground walking and treadmill training can be carried out.Various methods can promote the realization of hand use goals hand use, including the two-hand exercise training, constraint-induced moverment therapy, goal-oriented training and cognitive therapy.In terms of patient self-care, the guideline proposed that, the combination of full-task practice and auxiliary equipment can improve the independence of self-care and reduce the burden of care givers.Leisure goals could be achieved by the combination of the practice of the entire task with strategies to address environmental, personal, and social barriers.The intervention of children and adolescents with cerebral palsy should take into consideration of patient selection and the goal of full-task practice.The child/family preference, age and ability should be considered when clinical workers selecting specific interventions.

PURPOSE: This study aims to analyze the clinical-pathological characteristics of multifocal and multicentric breast cancer (MMBC) in Chinese women. METHODS: Sixty-seven cases with MMBC were randomly collected and reviewed at seven hospitals in representative districts of China during 1999 to 2008. RESULTS: The incidence of MMBC in breast cancer in China was 1.75%. Compared to those with unifocal breast cancer, women with MMBC were more likely to have larger tumor size, lymph node metastasis (59.70% vs. 45.62%) and stage III to IV (46.26% vs. 21.10%). The peak age at onset of MMBC was 40 to 49 years old and has been gradually increasing during 1999 to 2008. Most of the MMBC women were treated with surgery and adjuvant therapy. CONCLUSION: In China, the incidence of MMBC in breast cancer is significantly lower than that in Western countries. Compared to unifocal breast cancer, MMBC is biologically more aggressive. Most MMBC women underwent mastectomy, instead of breast conservation surgery.

Objective:To evaluate the consistency of the Chinese three-dimensional anterior visual field analysis system (Scansys), the anterior segment analyzer (Pentacam), the frequency-domain anterior segment optical coherence tomography system (CASIA SS-1000), and a new ultra-high frequency digital ultrasound scanning system (Arcscan Insight100) to measure central vault after implantable collamer lens (ICL) implantation in myopic eyes with crystalline lenses.Methods:A diagnostic test study was conducted.Fifty-six myopic patients (56 eyes) who underwent ICL V4c implantation from June to December 2019 were included.Scansys, Pentacam, CASIA and Arcscan were used to measure the central vault after surgery.The vault measurements were compared.Correlations between the measurements of the four instruments were analyzed using Pearson correlation analysis, and consistency comparisons were analyzed using the Bland-Altman method.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]). Written informed consent was obtained from each subject.Results:The central vault measurements by Scansys, Pentacam, CASIA and Arcscan were (481.8±191.6), (476.4±190.6), (619.3±207.5) and (534.0±221.2)μm, respectively, with a statistically significant overall difference ( F=143.301, P<0.001). The vault measurements by Scansys and Pentacam were significantly lower than CASIA and Arcscan, and Arcscan was lower than CASIA, with statistically significant differences (all at P<0.001). There were strong positive correlations in vault measurements between Arcscan and CASIA, Arcscan and Pentacam, Arcscan and Scansys, CASIA and Pentacam, CASIA and Scansys, Pentacam and Scansys ( r=0.982, 0.933, 0.931, 0.942, 0.941, 0.989; all at P<0.001). Intraclass correlation coefficients of vault measurements by Scansys, Pentacam, CASIA and Arcscan were 0.985, 0.975, 0.998, 0.992, respectively.The 95% limits of agreement of vault measurements differences were -170 to 0, 0 to 280, 0 to 280, -110 to 210, -100 to 220 μm, between CASIA and Arcscan, CASIA and Scansys, CASIA and Pentacam, Arcscan and Scansys, Arcscan and Pentacam, respectively, and the maximum absolute value of the difference was beyond the clinically acceptable range, showing poor agreement.The 95% limits of agreement of vault measurement difference was -60 to 50 μm between Scansys and Pentacam, showing a good agreement. Conclusions:The repeatability of the vault after ICL V4c implantation in myopic eyes measured by the four instruments is good.Among them, the vault measurements of Scansys and Pentacam are smaller, showing good consistency, and their results could be substituted for each other.The measurement of CASIA is the largest, followed by Arcscan, which have a large difference from each other, and their results can not be substituted for each other, which should be comprehensively analyzed with the actual situation in clinical work.
