ABSTRACT

Objective:To explore the association between dopamine-β-hydroxylase (DβH), norepinephrine transporter (NET) gene polymorphisms and panic disorder(PD).Methods:The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) axis Ⅰ disorders was administered by trained clinical psychiatrist, 139 patients with PD(PD group) and 196 healthy controls(control group) were enrolled in the study.Single nucleotide polymorphism(SNP) genotyping was performed using an improved multiplex ligation detection reaction technique.SPSS 16.0 and PLINK softwares were used to compare the allele frequency and genotype distribution.Results:(1)Compared with control group, PD group carried more G allele(76.3% vs 68.4%) and fewer A allele(23.7% vs 31.6%) in NET rs5569, and the difference was significant(χ 2=4.986, OR=0.67, 95% CI: 0.47-0.95, P<0.05). However, the correlation was no longer significant after adjusting for Bonferroni’s multiple testing( P>0.05). (2)The additive model of NET rs5569 showed a association with PD ( OR=0.68, 95% CI: 0.48-0.96, P<0.05). And the recessive model of DβH rs1611114 showed a association with PD( OR=0.42, 95% CI: 0.18-0.96, P<0.05). However, these correlations were no longer significant after adjusting for Bonferroni's multiple testing( P>0.05). (3)No matter allele or genotype, there were no significant differences in DβH (rs129882, rs1611114, rs1611115) and NET (rs2242446, rs28386840) gene polymorphisms between panic disorder group and control group(all P>0.05). Conclusion:The present study indicates that there is no significant association of DβH and NET gene polymorphisms with PD.

ABSTRACT

Objective:To explore whether microRNA-21-5p (miR-21-5p) has the effect of anti-apoptosis of human alveolar typeⅡ epithelial cells (ATⅡ).Methods:ATⅡ cells derived from the human were cultured in vitro and used for experiments when the cells were grown until the presence of lamellar bodies and microvilli were observed by light microscope. The cells were divided into blank control group (direct culture), hydrogen peroxide (H 2O 2) injury group (cultured with 0.5 mmol/L H 2O 2), and miR-21-5p overexpression group (using miR-21-5p with a multiplicity of infection (MOI) of 100 lentiviral overexpression vector with 0.5 mmol/L H 2O 2) and miR-21-5p empty virus control group (miR-21-5p lentiviral blank vector was co-cultured with 0.5 mmol/L H 2O 2). In each group, cell proliferation was detected by cell counting kit-8 (CCK-8) at 0, 12, 24, 36, and 48 hours of cell culture; cell apoptosis was detected by flow cytometry at 24 hours of culture. Results:① Cell proliferation activity test results: with the extension of cell culture time, the cell proliferation activity of the blank control group gradually increased, while the cell proliferation activity gradually decreased after the addition of 0.5 mmol/L H 2O 2. However, the cells proliferation activity in the miR-21-5p overexpression group decreased more slowly than that in the H 2O 2 injury group and the miR-21-5p empty virus control group, and the cell proliferation activity at 48 hours was significantly higher than the H 2O 2 injury group and the miR-21-5pempty virus control group ( A value: 0.295±0.005 vs. 0.184±0.005, 0.169±0.002, both P < 0.05). It showed that both H 2O 2 and lentivirus accelerated cell damage, while miR-21-5p could reduce cell apoptosis. ② Apoptosis rate test results: compared with the blank control group, the apoptosis rate increased significantly after adding 0.5 mmol/L H 2O 2; while the apoptosis rate of the miR-21-5p overexpression group was lower than that of the H 2O 2 injury group and miR-21-5p empty virus control group [early apoptosis rate: (14.31±0.12)% vs. (24.50±0.12)%, (23.41±0.13)%; late apoptosis rate: (8.12±0.13)% vs. (9.71±0.11)%, (10.41±0.15)%; overall apoptosis rate: (22.33±0.12)% vs. (34.21±0.10)%, (33.82±0.14)%; all P < 0.05], which further proved that miR-21-5p had anti-apoptotic effects. Conclusion:miR-21-5p has an anti-apoptotic effect on human ATⅡ.

ABSTRACT

Objective:To investigate the efficacy of dipeptidyl peptidase 4 inhibitor combined with insulin detemir (ID) in the treatment of type 2 diabetes mellitus with poor blood glucose control and its effects on blood glucose and oxidative stress indicators.Methods:A total of 105 patients with poor blood glucose control after taking oral hypoglycemic drugs who received treatment between August 2017 and September 2019 were included in this study. They were randomly assigned to receive treatment with either ID and compound vitamins (control group, n = 53) or dipeptidyl peptidase 4 inhibitor sitagliptin and ID (study group, n = 52). After 3 months of treatment, the clinical efficacy was compared between the control and study groups. Before and after 3 months of treatment, blood glucose indexes [fasting plasma glucose, 2-hour postprandial blood glucose], glycosylated hemoglobin, islet β-cell function [homeostasis model assessment-beta and homeostasis model assessment of insulin resistance)], oxidative stress index [superoxide dismutase, glutathione peroxidase, lipid hydroperoxides, malondialdehyde were compared between the two groups. The incidence of hypoglycemia was also recorded in each group. Results:After 3 months of treatment, total effective rate in the study group was significantly higher than that in the control group [92.31% (48/52) vs. 77.36% (41/53), χ2 = 4.541, P < 0.05]. After 3 months of treatment, fasting plasma glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, homeostasis model assessment of insulin resistance, lipid hydroperoxide and malondialdehyde levels in each group were significantly decreased, homeostasis model assessment-beta, superoxide dismutase and glutathione peroxidase levels were significantly increased compared with before treatment (all P < 0.05). There were significant significances in these indexes measured concurrently between the study and control groups ( t = 2.902, 3.539, 5.215, 7.313, 6.269, 4.475, 6.050, 3.323, 5.375, all P < 0.05). During the treatment, the incidence of hypoglycemia in the study group was significantly lower than that in the control group [0.00% (0/52) vs. 11.54% (6/53), χ2 = 4.319, P < 0.05]. Conclusion:Dipeptidyl peptidase 4 inhibitor combined with insulin detemir is highly effective for type 2 diabetes mellitus with poor blood glucose control. It can effectively control blood glucose level, improve oxidative stress reaction and is highly safe. Therefore, this treatment method is of good application value.

ABSTRACT

The processing of Chinese herbal medicine is a form of pharmaceutical technology developed over thousands of years, in order to increase efficiency and decrease toxicity of herbs in traditional Chinese medicine (TCM). Herbal processing is essential for safe and effective application of TCM in clinical practice, as it alters the active chemical components and therefore the functions of herbal medicines. Alkaloid-rich herbal medicines in TCM are commonly processed by cleansing, cutting, processing by dry stir-frying, stir-frying with liquid adjuvants, and processing by water decoction. In addition, commonly used adjuvants for processing alkaloid-rich herbal medicines are river sand, wine, vinegar, brine, honey and herbal juice. For alkaloid-rich herbal medicines, the main chemical reactions that occur during processing include hydrolysis, oxidation, replacement, decomposition and condensation. This paper aimed to summarize the processing methods and mechanisms for alkaloid-rich Chinese herbal medicines, and provide much-needed theoretical support and scientific evidence for understanding those mechanisms and effects. Information on processing methods for alkaloid-rich herbal medicines was collected from classic books of herbal medicine, PhD and MSc dissertations, online scientific databases including PubMed, SciFinder, Scopus, Web of Science, Baidu Scholar and Google Scholar. This paper should help to advance our knowledge of the processing mechanisms and aid in the development of processing methods for alkaloid-rich Chinese herbal medicines.

ABSTRACT

Objective@#To find out the association between family factors and left-behind children’s dietary behaviors in rural China.@*Methods@#This cross-sectional study was implemented in four counties of medium economic level were selected in Guizhou and Anhui province and four primary schools were chosen in each county and in total 16 schools were involved. Three classes from grades 5 and 6 each were selected randomly from included primary schools; all students in these classes, as well as their caregivers, were invited to participate. Self-designed questionnaire was adopted to collect intake frequencies of vegetable, fruit, meat, egg, milk, drink and fast food. Scores were calculated to evaluate these behaviors frequencies and multi-linear regression was used to explore the association between family factors and behavioral scores.@*Results@#The proportion of fruit, eggs and milk intake more than 4 times once a week in left-behind children were 44.9%, 35.1%, and 28.5%, while they were 57.2%, 38.5%, and 38.1% in non-left-behind children. It was found that statistical significant differences existed between scores of dietary behaviors of leftbehind children’s and non-left-behind children(t=-5.83, P<0.01). The results of multi-linear regression demonstrated that family cohesion (β=0.07, P=0.05) and caregivers’ behaviors (β=0.49, P<0.01) were protective factors for left-behind children’s behaviors, while taking care by single left-behind fathers was a risk factor(β=-1.21, P=0.03).@*Conclusion@#Primary caregivers play a critical role in offering guidance to children to help them develop health behaviors.

ABSTRACT

Objective:To observe the effects of T-2 toxin on expression of hepatocyte growth factor (HGF) and HGF receptor (C-Met) in articular cartilage and epiphyseal cartilage of rats under low selenium condition.Methods:Twenty-four healthy male SD rats weighted 60-80 g were randomly divided into conventional diet group (selenium content of 101.5 μg/kg) and low-selenium diet group (selenium content of 1.1 μg/kg), with 12 rats in each group. After 30 days of feeding, the conventional diet group was further divided into conventional group and T-2 toxin group (100 μg·kg -1·d -1), and the low-selenium diet group was further divided into low-selenium group and low-selenium+T-2 toxin group (100 μg·kg -1·d -1), with 6 rats in each group. After 30 days of feeding, the rats were sacrificed and the cartilage of knee joint was taken, the morphological changes of knee articular cartilage and epiphyseal cartilage were observed by HE staining under light microscope. Immunohistochemical method was used to detect the expression of HGF and C-Met in knee articular cartilage and epiphyseal cartilage, and positive expression rates of HGF and C-Met were calculated. Results:Under light microscope, chondrocytes of articular cartilage and epiphyseal cartilage in low-selenium+T-2 toxin group were sparse, and the necrosis and structural area were found in the deep layer, and the extracellular matrix of chondrocytes in the region was degraded and light stained, and proliferating granulation tissue was visible nearby. The positive expression rates of HGF in articular cartilage [(21.97 ± 6.90)%, (49.41 ± 8.24)%, (76.39 ± 5.88)%] and epiphyseal cartilage [(23.36 ± 12.49)%, (58.43 ± 14.48)%, (66.59 ± 10.83)%] of rats in low-selenium, T-2 toxin and low-selenium+T-2 toxin groups were higher than those in conventional group [(9.13 ± 6.01)%, (11.14 ± 4.67)%, P < 0.05]. The positive expression rates of C-Met in articular cartilage [(25.34 ± 7.53)%, (58.21 ± 12.54)%, (81.46 ± 7.89)%] and epiphyseal cartilage [(35.21 ± 4.71)%, (40.84 ± 2.03)%, (49.41 ± 6.29)%] of rats in low-selenium, T-2 toxin and low-selenium+T-2 toxin groups were higher than those in conventional group [(11.21 ± 5.11)%, (12.12 ± 4.71)%, P < 0.05]. Conclusion:T-2 toxin may affect the expression of HGF and C-Met in articular cartilage and epiphyseal cartilage of rats under low selenium condition.

ABSTRACT

OBJECTIVE: To investigate the change of pulmonary ventilation function in patients with simple type and complex type pneumoconiosis based on high resolution computed tomography(HRCT). METHODS: A total of 188 male patients with pneumoconiosis were selected as the study subjects by judgment sampling method. Patients were divided them into simple type group(104 cases) and complex type group(84 cases) according to their chest HRCT findings. Another 80 healthy men who have no dust and other occupational hazard exposure were selected as the control group. The lung function tests were performed in patients in these three groups. RESULTS: The indexes of pulmonary function including vital capacity, forced vital capacity(FVC), forced expiratory volume in one second(FEV_1), FEV_1/FVC%, peak expiratory flow, forced expiratory flow at 25% of FVC exhaled, forced expiratory flow at 50% of FVC exhaled, forced expiratory flow at 75% of FVC exhaled and forced expiratory flow at 25% to 75% of vital capacity were lower in patients with pneumoconiosis of simple type and complex type groups than that in the control group(all P<0.01). The above indexes in the complex type group were lower than that in the simple type group(all P<0.01). The detection rate of pulmonary ventilation dysfunction in patients with pneumoconiosis was 64.9%. Among them, the detection rate of obstructive, restrictive and mixed ventilation dysfunction were 33.5%, 5.3% and 26.1%, respectively. The detection rates of pulmonary ventilation dysfunction and mixed ventilation dysfunction were higher in complex type group than that in simple type group(82.1% vs 51.0%, 41.7% vs 13.5%, all P<0.01). The severe and extremely severe pulmonary ventilation dysfunction was higher in complex type group than that in simple group(20.2% vs 8.6%, 21.4% vs 3.8%, all P<0.05). CONCLUSION: The types of pulmonary ventilation dysfunction in patients with pneumoconiosis are mainly obstructive and mixed. The pulmonary ventilation dysfunction tends to develop from obstructive to mixed with the increasing severity of pneumoconiosis. The pulmonary ventilation dysfunction in patients with complex type pneumoconiosis is more serious than that in patients with simple type pneumoconiosis. The HRCT image classification is related to the status of patients' pulmonary ventilation dysfunction.

ABSTRACT

Objective:To investigate the effects of Buyang Huanwu Tang (BHT) on axonal regeneration and neurological rehabilitation of the rats suffering ischemic stroke (IS). Method:A total of 180 SD rats were used to establish a middle cerebral artery infarction (MCAO) model. The animals that were successfully modeled were randomly divided into model group, BHT group (12 g·kg-1) and nimodipine group (20 mg·kg-1), and a sham group was established, with 28 rats in each group. After seven-days intragastric administration of BHT, the animals were sacrificed. TTC staining was used to test cerebral infarction. Brain water content was measured to observe cerebral edema. Bielschowsky's silver staining and immunofluorescence were performed to observe axonal degeneration and the protein expression of neurofilament protein-200(NF-200). Quantitative real-time polymerase chain reaction (PCR) was used to analyze the mRNA expression of repulsion oriented molecule a (RGMa), Ras homologous enzyme (Rho), Rho kinase (ROCK), and collapsion response regulatory protein 2 (CRMP2). Neurological function scores assay was used to examine neurological recovery. Result:Compared with sham group, the cerebral infarction volume and brain water content increased significantly(P<0.01), and motor function was markablely decreased in the model group. Axonal degeneration and nerve fiber damage were obviously observed. Also, gene expression of axon growth-related protein was deviation from normal (P<0.01). Compared with model group, the cerebral infarction rate (P<0.01), brain water content (P<0.01) and axonal degeneration of BHT group and nimodipine group were significantly reduced. The expression of NF-200 was increased. Also, the mRNA expression of RGMa, Rho and ROCK was lower (P<0.05) while the mRNA expression of CRMP2 was higher (P<0.01). And the neurological function was significantly improved (P<0.05). Conclusion:BHT can promote axon regeneration after ischemic stroke injury by regulating the mRNA expression of axon growth-related protein, thereby improving nerve function.

ABSTRACT

Objective@#To explore the changes of awareness of tuberculosis and access to tuberculosis-related information among students in Zhejiang Province.@*Methods@#There were 554 students younger than 30 y were included in the study during April to sept. of 2014 and during sept. to Nov. of 2018. Univariate and multivariate Logistic regression were conducted to find the related factors of knowing about tuberculosis and related knowledge. Chi-square test was used to analyze the changes of ways access to tuberculosis-related information.@*Results@#There were 440 participants (79.4%) aware of tuberculosis, including 215(85.7%) in 2014 and 225(74.3%) in 2018. The factors affecting awareness on tuberculosis were female ( AOR=1.60, 95%CI =1.04-2.47) vs male; and junior middle school( AOR=1.99, 95%CI =1.03-3.85), high school( AOR=3.27, 95%CI =1.57-6.81), college or higher ( AOR=6.73,95%CI =2.55-17.76) vs primary school or lower; year 2018 ( AOR=0.50, 95%CI =0.31-0.80) vs 2014. There was no significant statistical difference in the overall knowledge scores of tuberculosis between the students in the two surveys. In 2018, the proportion of tuberculosisrelated information accessed from the Internet (forum, WeChat, Weibo.) and community activities (assembly promotion)(75.10%, 26.70%) was higher than that of 2014(36.20%, 13.10%)( χ 2=68.88, 12.79, P <0.05).@*Conclusion@#The proportion of students aware of tuberculosis and TB control in Zhejiang Province were not significantly improved. Higher proportion of students get tuberculosis-related information from the new media. Therefore, it is necessary to strengthen health education of tuberculosis in schools, especially through the usage of new media apart from traditional pathways.

ABSTRACT

OBJECTIVE@#To explore the value of has-microRNA-155 (miR-155) in peripheral blood mononuclear cells (PBMNC) in prognostic evaluation of elderly patients with primary immune thrombocytopenia (PITP).@*METHODS@#One hundred and thirty elderly PITP patients and 60 healthy volunteers in our hospital were selected. The relative expression level of miR-155 in PBMNC was detected by RT-PCR. Unconditional logistic multivariate regression analysis was used to analyze the relationship between miR-155 expression and prognosis of PITP patients, and Kaplan-Meier was further used to analyze the relationship between miR-155 and PITP recurrence.@*RESULTS@#The relative expression level of miR-155 in PBMNC of elderly PITP patients was significantly higher than that in healthy volunteers, and increased significantly with the severity of the disease (P<0.05). The overall effective rate of elderly PITP patients with miR-155 low-expression was significantly higher than that in the patients with miR-155 high-expression (96.92% vs 72.31%) by after treatment with glucocorticoid. Multivariate analysis showed that miR-155 was an independent risk factor for PITP patients. Elderly patients with high expression of miR-155 showed a higher risk of recurrence.@*CONCLUSION@#miR-155 in PBMNC has a high accuracy for PITP diagnosis, and the elderly patients with high level of miR-155 show a poor prognosis and a higher risk of recurrence.

ABSTRACT

Research suggests that inflammation is important in the pathophysiology of mental disorders. In addition, a growing body of evidence has led to the concept of the microbiota-gut-brain axis. To understand the potential interactions, we begin by exploring the liaison between the immune system and mental disorders, then we describe the evidence that the microbiota impact the immune response in the developing brain. Next, we review the literature that has documented microbiome alterations in major mental disorders. We end with a summary of therapeutic applications, ranging from psycho-biotics to immunomodulatory drugs that could affect the microbiota-gut-brain axis, and potential treatments to alleviate the adverse effects of antipsychotics. We conclude that there is promising evidence to support the position that the microbiota plays an important role in the immunological pathophysiology of mental disorders with an emphasis on psychotic disorders and mood disorders. However, more research is needed to elucidate the mechanisms.

ABSTRACT

Objective:To evaluate the effects of rocuronium on limb ischemia-reperfusion injury in the patients undergoing total knee arthroplasty.Methods:Ninety patients of both sexes, aged 50-80 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, with body mass index<30 kg/cm 2, scheduled for elective unilateral knee arthroplasty under general anesthesia combined with femoral nerve block from January 2019 to October 2019, were divided into 3 groups ( n=30 each) using a random number table method: normal saline group (group S), rocuronium 0.6 mg/kg group (group RL) and rocuronium 1.2 mg/kg group (group RH). Anesthesia was induced by intravenous injection of midazolam, etomidate, sufentanil and rocuronium 0.6 mg/kg (group RL) or 1.2 mg/kg (group RH) or equal volume of normal saline (group S). Mechanical ventilation was performed after placement of laryngeal mask to maintain P ETCO 2 35-45 mmHg.Femoral nerve block was performed under ultrasound guidance.Anesthesia was maintained by inhaling 1% sevoflurane and intravenous infusion of propofol and remifentanil to maintain entropy index at 40-60 during operation.Patient-controlled intravenous analgesia was performed with sufentanil after surgery to maintain visual analogue scale score ≤ 4 points.When visual analogue scale score was > 4, flurbiprofen axetil 100 mg was intravenously injected.The vastus medialis muscle at the edge of the incision was obtained at 60 min after inflation to determine the expression of dystrophin by immunohistochemistry.Arterial blood samples were collected immediately after inflation of the tourniquet, at 60 min after inflation, and at 5 and 30 min after deflation for determination of the serum malondialdehyde (MDA) concentrations by the thiobarbituric acid method.The effective pressing times of the analgesic pump and consumption of sufentanil and flurbiprofen axetil were recorded within 48 h after operation.The occurrence of responses to tourniquet and residual muscle relaxation during recovery from anesthesia, the first postoperative off-bed time and postoperative length of hospital stay were recorded.The thigh girth was measured before operation and at 24 and 48 h after operation, and the difference after and before operation was calculated.The range of motion of knees of the operated limb and tourniquet-related complications in the early postoperative period (3 days) and in the long-term postoperative period (3 months) were recorded. Results:Compared with group S, the expression of dystrophin in skeletal muscle was significantly up-regulated, the concentration of serum MDA was decreased at 30 min after deflation, and the difference in thigh girth at 24 and 48 h after operation was decreased in group RH, and the range of motion of knees was significantly increased at 3 days and 3 months after operation, and the first postoperative off-bed time was shortened in group RH and group RL ( P<0.05). Compared with group RL, the range of motion of knees was significantly increased at 3 days and 3 months after operation, and the first postoperative off-bed time was shortened in group RH ( P<0.05). There was no significant difference in the incidence of responses to tourniquet, postoperative length of hospital stay, effective pressing times of the analgesic pump, postoperative consumption of sufentanil and flurbiprofen axetil, and the incidence of tourniquet-related complications in the early and long-term postoperative periods among the three groups ( P>0.05). No residual muscle relaxation was found during recovery from anesthesia in three groups. Conclusion:Rocuronium 1.2 mg/kg can reduce limb ischemia-reperfusion injury in the patients undergoing total knee arthroplasty.

ABSTRACT

Objective@#To investigate the awareness of pubertal knowledge and its influencing factors among primary school students in Chinese rural areas, and to provide evidences for improving awareness level and popularizing scientific, reasonable, and suitable sex education.@*Methods@#Sixteen primary schools consisting of rural registered students in Guizhou and Anhui Province were selected by multi-stage cluster sampling method, and a questionnaire survey for 2 506 senior students (grade five and six) was conducted to explore the awareness of pubertal knowledge and its influencing factors among primary school students in Chinese rural areas.@*Results@#The total awareness rate of pubertal knowledge was 62.7% among primary school students in Guizhou and Anhui rural areas, and the awareness rates were relatively low for the questions about the difference between male and female pubertal development and understanding of sexual attitude; female students, only-child students and grade six students got a bit better awareness of pubertal knowledge than male students, non-only-child students and grade five students respectively; grade[OR=0.72(0.61-0.86)], peer acceptance [OR=0.70(0.53-0.96)], family intimacy [OR=0.75(0.63-0.88)] had effect on awareness of pubertal knowledge.@*Conclusion@#The awareness of pubertal knowledge among primary school students in Guizhou and Anhui rural areas need further improvement, especially for male students, non-only-child students and grade five students in the questions about the difference between male and female pubertal development and understanding of sexual attitude. It is necessary to improve the awareness of pubertal knowledge by enhancing peer acceptance, promoting family intimacy, and popularizing scientific, reasonable, and suitable sex education.

ABSTRACT

OBJECTIVE: To study the effects of cimetidine on low dose rate irradiation-induced liver cell apoptosis in Beagle dogs. METHODS: Healthy male Beagle dogs were randomly divided into normal control group, model control group, positive drug group (lentinan, 21.33 mg/kg) and cimetidine low-dose, medium-dose and high-dose groups (5.33, 10.67, 21.33 mg/kg), with 4 Beagle dogs each. Except for normal control group, other groups were given 60Co-γ accumulative irradiation (dosage rate: 0.040 8 mGy/min) for 23 d; the medication groups were given relevant medicine orally before irradiation, once a day. Twenty-four hours after stopping irradiation, TUNEL method was used to detect the apoptosis of liver cells in Beagle dogs. The percentage of apoptotic cells was calculated. The expression level of apoptosis-related proteins (Bax, Bcl-2, Caspase-3, p53) in liver tissue was detected by immunohistochemistry. RESULTS: Compared with normal control group, apoptotic cells and Bax, Caspase-3, p53 positive cells were increased significantly in liver tissue of Beagle dogs in model control group; the percentage of apoptotic cells, protein expression levels of Bax, Caspase-3 and p53 were increased significantly; Bcl-2 positive cells were decreased significantly, and its protein expression level was decreased significantly (P<0.05 or P<0.01). Compared with model control group, above positive cells of liver tissue in Beagle dogs were changed to different extents in medication groups; the percentage of apoptotic cells and protein expression levels of p53 in medication groups, protein expression levels of Bax in positive drug group, cimetidine low-dose and high-dose groups as well as protein expression levels of Caspase-3 in cimetidine groups were decreased significantly; protein expression levels of Bcl-2 were increased significantly in cimetidine groups. The percentage of apoptotic cells in cimetidine medium-dose and high-dose groups as well as protein expression levels of Caspase-3 in cimetidine groups were all lower than positive control group. Protein expression level of p53 in cimetidine low-dose group was significantly higher than positive drug group (P<0.05 or P<0.01). CONCLUSIONS: Cimetidine can inhibit the low dose rate irradiation-induced apoptosis of liver cells in Beagle dogs, and certainly protect liver cells against irradiation. The mechanism of it may be associated with up-regulating the protein expression of Bcl-2 and down-regulating the protein expression of Bax, Caspase-3 and p53 in liver cells.
