Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

Objective To investigate the onset of left ventricular remodeling (LVRM) after acute myocardium infarction (AMI) and its changes within 6 hours in dogs on echocardiography. Methods AMI was induced in 14 dogs by ligating the left anterior descending arteries. Eight myocardium infarcted models were successful and were sacrified for pathological study. The indices of LVRM: wall infarction thickness (WIT), the wall motion score index (WMSI), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were evaluated before and 1 h, 2 h, 3 h, 4 h, 5 h and 6 h after operation. Results Compared with the pre-operation, WIT and LVEF were decreased (P<0.01), LVESV and WMSI were increased (P<0.01), and LVEDV was increased (P<0.05 or P<0.01) at every time point after operation. WIT had no significant difference at 1 h, 2 h, 3 h, 4 h, 5h and 6h after operation (P＞0.05). LVEDV, LVESV were higher (P<0.05) and LVEF was lower (P<0.05 or P<0.01) at 4 h, 5 h, and 6 h than at 1 h, and 2 h after operation. WMSI was higher at 3 h, 4 h, 5 h, and 6 h than at 1h (P<0.05). Conclusions In our experiment, LVRM occurred at 1 h after AMI in dogs. Thus echocardiography may evaluate early LVRM.

Objective To explore the relationship between adult tobacco use and health literacy, and to provide evidence for tobacco control intervention and health promotion. Methods By combining PPS method and KISH table method, the 2018 National Residents′ Health Literacy Monitoring Questionnaire was used to investigate the health literacy level and tobacco use, and the correlation between current smoking behavior and health literacy among residents aged 15-69 was analyzed by logistic regression. Results A total of 3 200 people were surveyed, and 3 185 valid questionnaires were recovered, with an effective rate of 99.53%.The current smoking rate of people with scientific health literacy, infectious disease prevention literacy, safety and first aid literacy, basic medical literacy and health information literacy was lower than those without (P < 0.05).The results of multivariate logistic regression analysis showed that the current smoking rate of males was higher than that of females (OR=25.900, 95%CI:17.018-39.416).The current smoking rates in groups aged 25-69 were higher than those in groups aged 15-24 (OR=4.956-9.178, 95%CI:1.179-37.940).The current smoking rates of workers, employees of other enterprises and other professionals were higher than those of employees of government institutions (OR=1.488-1.913, 95%CI:1.082-3.055).People without basic medical literacy had a higher smoking rate than those with basic medical and health literacy (OR=1.366, 95%CI:1.057-1.765). Conclusion From now on, we should carry out health literacy promotion and tobacco control propaganda for key groups, improve the level of basic medical and health literacy and reduce the smoking rate.

Abstract: Objective　To investigate the clinical characteristics and incidence of Brucella encephalitis and meningitis in children. Methods We report the clinical data of a child with Brucella melitensis meningitis in children, and summarize the incidence, diagnosis methods and treatment of Brucella encephalitis or meningitis in children, taking into account the relevant domestic and foreign literature from January 2014 to December 2020. Results　A 4-year-old girl was admitted to the hospital with status epilepticus on March 15, 2021 because of interrupted right limb numbness for 16 hours and convulsions for 2 hours. She had 2 non-febrile convulsions three months before admission and was diagnosed with epilepsy. This incident was acute, accompanied by low fever, with epilepsy as the main manifestation. Cerebrospinal fluid test suggested central nervous system infection, but the nature of infection could not be determined by routine and biochemistry of cerebrospinal fluid.The cerebrospinal fluid next generation sequencing confirmed that the pathogen of the infection was B. melitensis, which was further verified by the peripheral blood antibody test. After effective antibiotics combined with a full course of treatment, the patient recovered after six months of treatment. A total of 60 articles were retrieved in the database, including 29 in Chinese. During this period, a total of 7 cases of brucellosis in children with nervous system involvement were reported, one of which was a case report, and the other 6 cases were mentioned in the comprehensive analysis of children with brucellosis. Conclusions　Brucella encephalitis or meningitis in children has a low incidence and various clinical features, which are easy to be misdiagnosed or missed.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg^-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg^-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (P<0.05) the content of thyroid stimulating hormone (TSH) and luteinizing hormone (LH). In serum samples, 38 biomarkers such as corticosterone, L-phenylalanine, and DL-tryptophan were measured as possible indicators for disease development in KYD rats. MT-2 lowered 18 biomarkers of KYD, including corticosterone, deoxycorticosterone, and L-phenylalanine, and altered 13 related metabolic pathways including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and steroid hormone biosynthesis, resulting in an overall improvement in KYD. MT-2 appears to be important in improving KYD in rats mainly by regulating metabolites such as amino acids, steroids and lipids.

BACKGROUNDThe successful end-point of in vitro fertilization (IVF) treatment is for a woman to give live birth. This outcome is based on various factors including adequate number of retrieved eggs. Failure to recruit adequate follicles, from which the eggs are retrieved, is called a "poor response". How to improve the clinical pregnancy rates of poor responders was one of the tough problems for IVF.

METHODSThe study involved 51 patients who responded poorly to high dose gonadotropin treatment in their previous cycles at our reproductive center, between April 2010 and February 2012. The previous cycle (group A) received routine long protocol; the subsequent cycle (group B) received modified super-long down-regulation protocol. The primary outcome of the study was the number of oocytes fertilized. The increase in the pregnancy rate was the secondary outcome. Differences between the groups were assessed by using Student's t test and c(2) test where appropriate.

RESULTSThe patients' average age was (36.64 ± 3.85) years. The mean duration of ovarian stimulation cycles of the group A patients was longer than those of the group B patients. The total dose of follicle-stimulating hormone (FSH) was significantly lower in the subsequent cycle. The peak value of serum estradiol on human chorionic gonadotrophin (hCG) day was lower in group A as compared with group B. The number of metaphase II oocytes recovered was significantly higher in group B. The cleavage rate in group A was significantly lower than in group B, 49 patients in group B reached embryo transfer stage, while 46 patients in group A reached this stage. Patients in group B received significantly more embryos per transfer as compared with group A. More pregnancies and more clinical pregnancies with fetal heart activity were achieved in group B.

CONCLUSIONSThis comparative trial shows that poor responder women undergoing repeated assisted reproduction treatment using modified super-long down-regulation protocol achieve more oocytes, leading to higher fertilization rate, compared to women receiving routine long protocol. Our study also showed that clinical pregnancy rate was significantly improved.

OBJECTIVETo investigate the effects of the combination of musk and olibanum on the tight junction protein expressions in prostatic epithelial cells of normal and chronic prostatitis (CP) rats.

METHODSEighty male SD rats were randomly divided into 8 groups of equal number: normal control, normal musk, normal olibanum, normal musk + olibanum, CP model control, CP model musk, CP model olibanum, and CP model musk + olibanum. At 60 days after modeling, the rats in the control, musk, olibanum, and musk + olibanum groups were treated intragastrically with normal saline, musk (0.021 g per kg body weight per day), olibanum (1.05 g per kg body weight per day), or musk + olibanum respectively, all for 3 days. Then, all the rats were sacrificed and their prostate tissues harvested for detection of the expressions of the tight junction proteins Claudin-1, Claudin-3, Occludin, and ZO-1 in the prostatic epithelial cells by immunohistochemical staining.

RESULTSIn the CP models, only the expression of Claudin-1 was significantly increased. In the normal rats, the expression of Claudin-1 was remarkably upregulated after treated with musk (824.6 ± 393.3, P < 0.05), olibanum (982.0 ± 334.0, P < 0.05), and musk + olibanum (1088.1 ± 640.2, P < 0.01); that of Claudin-3 was elevated markedly by olibanum (1 009.5 ± 243.6, P < 0.05) and insignificantly by musk (597.5 ± 80.7), but the increasing effect of olibanum was reduced by musk + olibanum (678.4 ± 255.1). No statistically significant differences were found in the expression of Occludin among the rats treated with musk (693.0 ± 424.8), olibanum (732.1 ± 302.0), and musk + olibanum (560.2 ± 202.3), or in that of ZO-1 in the animals treated with musk (290.0 ± 166.8) and olibanum (419.7 ± 108.1), but the latter was markedly decreased in the musk + olibanum group (197.7 ± 98.2, P < 0.05). In the CP rat models, both the expressions of Claudin-1 (823.0 ± 100.1, P < 0.01) and Occludin (1160.0 ± 32.2, P < 0.05) were significantly increased. The expression of Claudin-1 was remarkably down-regulated by musk (764.9 ± 179.0), olibanum (468.4 ± 220.4), and musk + olibanum (335.1 ± 204.0) (all P < 0.05), but that of Claudin-3 up-regulated by musk (744.6 ± 94.5) and olibanum (700.1 ± 223.7) (both P < 0.05). The expression of Occludin was reduced by musk (615.0 ± 221.0), olibanum (749.6 ± 321.7), and musk + olibanum (505.8 ± 523.7), while that of ZO-1 increased by olibaum (443.2 ± 44.9) and decreased by musk + olibanum (213.5 ± 24.9, P < 0.05).

CONCLUSIONIn physiological and pathological conditions, the combination of musk and olibanum acts on the expressions of tight junction proteins in prostate epithelial cells in a selective and dual-targeting manner, promoting their permeability by down-regulating the expression of ZO-1 and maintaining their structural stability by regulating the expressions of Claudin-1, Claudin-3, and Occludin.
