OBJECTIVETo investigate the effect of tanshinone II(A) on the expression of different components in the renin-angiotensin system of left ventricles of renal hypertensive rats.

METHODThe renal hypertension model was established in rats by the two-kidney-one-clip (2K1C) method. In the experiment, all of the rats were randomly divided into four groups (n = 15 per group) before the operation: the sham-operated (Sham) group, the hypertensive model (Model) group, the low-dose tanshinone II(A) group and the high-dose tanshinone II(A) group. At 5 week after the renal artery narrowing, the third and fourth groups were administered with 35 mg kg(-1) x d(-1) and 70 mg x kg(-1) x d(-1) of tanshinone II(A), respectively. The blood pressure in rats was determined by the standard tail-cuff method in each week after the operation. After the drug treatment for 8 weeks, all the rats were put to death, and their left ventricles were separated to determine the ratio of left ventricle weight to body weight (LVW/BW), the myocardial collagen content, and the expressions of different components in myocardial RAS, including angiotensin converting enzyme (ACE), angiotensin converting enzyme 2 (ACE2), angiotensin 1-type receptor (AT1R), Mas receptor mRNA expression and angiotensin II (Ang II) and angiotensin (1-7) [Ang (1-7)] content.

RESULTCompared with the sham group, the hypertensive model group exhibited a markable increase in the content of Ang II and Ang (1-7) and the mRNA expressions of ACE, ACE2, AT1R and Mas (P < 0.01). However, the treatment with tanshinone II(A) showed the does dependence, inhibited left ventricle hypertrophy, decreased myocardial Ang II content and the mRNA expression of ACE and AT, R in renal hypertensive rats (P < 0. 01) , further increased the myocardial Ang (1-7) content and the mRNA expression of ACE2 and Mas (P < 0.01) , but without any change in the blood pressure of hypertensive rats.

CONCLUSIONThe treatment with tanshinone II(A) could inhibit left ventricle hypertrophy of renal hypertensive rats. Its mechanism may be partially related to the expression of different components in the renin-angiotensin system for regulating myocardial tissues.

Background A preliminary study determined an application of manganese ion eyedrops in tracing observation of visual system in vivo,but whether manganese ion has toxic effects on ocular anterior segment tissues is still unclear.Objective This study was to investigate the toxic effects of different concentrations of manganese ion eyedrops on ocular anterior segment tissues.Methods Thirty-two clean New-Zealand white rabbits were divided into 1.00 mol/L MnCl2 group,0.50 mol/L MnCl2 group,0.25 mol/L MnCl2 group and normal control group according to random number table.The experimental eye was randomly chosen from each rabbit for eyedrops application.The manganese ion eyedrops at concentration of 1.00 mol/L,0.50 mol/L or 0.25 mol/L was topically administered in any lateral eye of each rabbit in the 1.00 mol/L MnCl2 group,0.50 mol/L MnCl2 group,0.25 mol/L MnCl2 group,and normal saline solution was used in the same way in the normal control group.In 2 hours,1 day and 3,7,14,21,28 days after eyedrops application,the irritative response of ocular surface was examined under the slit lamp microscope,and corneal damage was evaluated by corneal fluorescence staining,and corneal endothelial cell density (ECD) and corneal thickness were assessed using corneal specular microscope.The eyeball samples were prepared in 3,7,14 and 28 days after eyedrops application and hematoxylin and eosin staining was performed for histopathological examination of conjunctiva,cornea,trabecular meshwork and ciliary body tissue.The use and care of experimental animals complied with the Statement of ARVO.Results Severe hyperemia and edema in palpebral conjunctiva appeared in the 1.00 mol/L MnCl2 group and 0.50 mol/L MnCl2 group,and the symptoms reached a maximum level 1 day after eyedrop application and disappeared 7 days after eyedrops application in the 1.00 mol/L MnCl2 group.These symptoms were milder in the 0.50 mol/L MnCl2 group in comparison with the 1.00 mol/L MnCl2 group.There were no ocular irritative response in the 0.25 mol/L MnCl2 group.Significant differences were found in the corneal fluorescence scores among the groups 2 hours,1 day,3 and 7 days after eyedrop application (X2 =17.350,19.200,12.200,10.140,all at P＜0.05),with the highest score in the 1.00 mol/L MnCl2 group.The ECD was not significantly different among the groups and different time points (Fgroup =0.38,P＞0.05;Ftime =1.79,P＞0.05).The corneal thickness value was significantly different among the groups and different time points (Fgroup =18.22,P＜0.05;Ftime =116.75,P ＜ 0.05).The corneal thickness value was elevated during 2 hours to 3 days after administration of eyedrops in the 1.00 mol/L MnCl2 group and closed to normal from 7 days to 28 days.The corneal thickness value was higher from 2 hours to 14 days than that in 28 days after administration of eyedrops in the 1.00 moL/L MnCl2 group,and the corneal thickness value was higher in 2 hours to 1 day than that in 28 days after administration of eyedrops in the 0.50 mol/L MnCl2 group (all at P＜0.05).Inflammatory cell infiltration and stromal edema were exhibited in conjunctival,trabecular meshwork and ciliary body tissue in the 1.00 mol/L MnCl2 group 3 days and 7 days after eyedrops application,and only inflammatory cell infiltration in conjunctival tissue in the 0.50 mol/L MnCl2 group 3 days after eyedrops application.No obvious abnormity was seen in the 0.25 mol/L MnCl2 group.Conclusions 1.00 mol/L manganese ion eyedrops has a remarkable toxic effect on ocular anterior segment tissue in rabbit.With the lowing of drug concentrations,the toxic effects were reduced.The manganese-enhanced MRI using 0.25 mol/L manganese ion eyedrops is feasibility bacause of its non-toxicity to ocular tissues.

Objective To investigate insulin-like growth factor-1(IGF-1) on the protective effect of infant myocarditis.Methods The serum levels of IGF-1 was detected by two-site enzyme-linked immunosorbent assy ( ELISA) and CK-MB by electrochemiluminescence at the acute and convalescent in 50 infant with myocarditis,and 50 normal healthy children as the controls.Results The serum levels of IGF-1 in acute myocarditis was significantly lower than those of healthy children and the convalescen[(22.90 ±9.30) mg/L vs (45.69 ±10.95) mg/L, (38.99 ±9.06)mg/L,all P<0.01],while the CK-MB was significantly higher than those of the control group and the convalescent[(77.48 ±8.71)mg/L vs (14.99 ±7.62)mg/L,(17.99 ±6.31)mg/L,all P<0.01.IGF-1 and CK-MB was negative correlation (r=-0.62,P<0.01).Conclusion IGF-1 is involved in the repair process of myocardial injury in myocarditis infant,and play some protective role in the mechanism.

Objective To study the variation of acute blood pressure in different subtypes of first ischemic stroke,and investigate the influence on the prognosis.Methods A total of 710 patients with first ischemic stroke were selected.The blood pressure levels were monitored during the initial 7 hospital days.Clinical outcome was based on the combined analysis of Barthel index and the National Institute of Health Stroke Scale (NIHSS) score on the 180th day.In the subtypes of large artery atherothrombosis(LAA),cardioembolism (CE),small artery disease occlusion (SAO) were 400,160,150 cases.Logistic regression model was used to estimate the influencing factors on the prognosis.Results An U-shaped effect was observed in different subtypes between blood pressure on admission,average acute blood pressure and prognosis.In the subtypes of LAA and CE,those who had a basehne systolic blood pressure (SBP) of 140-159 mm Hg (1 mm Hg =0.133 kPa) or a baseline diastolic blood pressure (DBP) of 90-99 mm Hg on admission got good prognosis.In the subtypes of SAO,those who had a baseline blood pressure of 130/95 mm Hg on admission got good prognosis.In all subtypes,the average blood pressure of 150/95 mm Hg got good prognosis.In the subtypes of LAA and CE,those who had a baseline SBP of 120-159 mm Hg or a baseline DBP of 80-99 mm Hg within 7 d after admission got good prognosis.In the subtypes of SAO,those who had a baseline blood pressure of 140/90 mm Hg within 7 d after admission got good prognosis.In all subtypes,the average blood pressure of 140/90 mm Hg within 7 d after admission got good prognosis.Logistic regression analysis revealed that the decrease of blood pressure during the first 24 hours,deterioration within 7 d after admission,acute complication,NIHSS score on admission were the independent risk factors of prognosis,while antihypertensive therapy in the acute phase was the independent protection factor in the subtypes of LAA and CE.In the subtypes of SAO,acute complication was the independent risk factor of prognosis.Conclusions An U-shaped effect is observed in different subtypes between blood pressure on admission and prognosis.In the subtypes of LAA and CE,the decrease of blood pressure during the first 24 hours,deterioration within 7 d after admission,acute complication,NIHSS score on admission are the independent risk factors of prognosis.

OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

OBJECTIVE:To investigate the effects of Melilotus extract tablet on postoperative therapeutic efficacy of chronic sinusitis endoscopic surgery and the recovery of nasal mucosa. METHODS:The clinical data of 100 patients undergoing chronic si-nusitis functional endoscopic surgery in our hospital from May 2015 to Oct. 2016 were analyzed retrospectively and they were divid-ed into control group and observation group according to postoperative treatment,with 50 cases in each group. Two groups received anti-inflammatory,anti-histamine and hemostasis therapy. The control group received Eucalyptol,linonene and pinene enteric soft capsules 0.3 g,tid;observation group was additionally given Melilotus extract tablet 1.2 g,tid,for 6 weeks,on the basis of con-trol group. VAS and Lund-Kennedy endoscopic score were compared between 2 groups before and after treatment. Clinical effica-cies and the occurrence of ADR were also compared between 2 groups. RESULTS:there was no statistical significance in VAS score and its total score,Lund-Kennedy endoscopic score and its total score between 2 groups before treatment (P>0.05). After treatment,VAS score and its total score,Lund-Kennedy endoscopic score and its total score of 2 groups were significantly de-creased,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The cure rate of observation group was 72.0%,which was significantly higher than 44.0% of control group,with statistical significance (P<0.05). There was no significant difference in the incidence of adverse reactions between the 2 groups (P>0.05). CONCLU-SIONS:Melilotus extract tablet helps to improve clinical efficacy and the recovery of nasal mucosa in patients with chronic sinus-itis after endoscopic surgery,with good safety.
