BACKGROUND: Lanceolata and astragalus can improve myocardial ischemia, which are widely used in clinics.OBJECTIVE: To compare the effects of extract of lanceolata and astragalus on electrocardiogram (ECG) of rats with experimental myocardial ischernia.DESIGN: Completely randomized and controlled study.SETTING: Pharmacological College of Harbin Commerce University.MATERIALS: The experiment was carried out at the Laboratory of Pharmacological College of Harbin Commerce University from September to December 2002. Totally 30 healthy adult Wistar rats were divided randomly into 3 groups: control group, lanceolata group and astragalus group with 10 in each group.METHODS: ① After anesthesia, lead ECG Ⅱ of rats was recorded.30 g/kg saline, 30 g/kg lanceolata extract and 30 g/kg astragalus extract [extract of lanceolata and astragalus (raw drug: 1 g/mL)] were injected into rats in the control group, lanceolata group and astragalus group respectively. After 1-3 minutes, 0.5 U/kg pituitrin was injected intravenously (for model of myocardial ischemia), and then saline was used to dilute from 0.1to 0.2 mL for 10-second injection. Changes of ECG after injection of pituitrin were recorded with LMA-2B Ⅱ physiological recorder (migration of T wave and ST section and change of heart rate). ② Differences of data were compared with t test.MAIN OUTCOME MEASURES: Height of T wave and Migrations of ST section and changes of heart rate of ECG of rats before and after medication.RESULTS: Data of totally 30 rats was entered the final analysis. ①Height of T wave: The height was higher after medication than that before medication in three groups (P ＜ 0.01), but that in astragalus group was obviously lower than that in lanceolata group [(1.63±3.81), (2.18±2.93) mm,P ＜ 0.01]. ② Heart rate: The rate was lower after medication than that of before medication in three groups (P ＜ 0.01), and that in astragalus group was obviously lower than that in lanceolata group [(212.21 ±5.01),(221.18±5.66) time/minute, P ＜ 0.01]. ③ Height of ST section: There were not significantly different in three groups (P ＞ 0.05), and the difference was not obvious before and after medication (P ＞ 0.05).CONCLUSION: ① Both astragalus and lanceolata can protect experimental myocardial ischemia induced by pituitrin. ② Effect of lanceolata on reduction of T-wave height is stronger than that of astragalus, but the effect of lanceolata on reduction of heart rate is weaker than that of astragalus.

Objective To evaluate the clinical efficacy and safety of a fractional bipolar radiofrequency device for the treatment of wrinkles of the face and neck.Methods This study enrolled 39 volunteers (including 37 females and 2 males aged 35-60 years) with Fitzpatrick skin type Ⅳ-Ⅴ and Fitzpatrick wrinkle scale score of 4-6.All the subjects received three sessions of treatment with a fractional bipolar radiofrequency device at intervals of 4-6 weeks.Follow-up visits were scheduled at one month after each treatment session for evaluation of efficacy (using standardized photography),subjective satisfaction and adverse effects.Results After three sessions of treatment,all the subjects experienced a significant decrease in Fitzpatrick wrinkle scale compared with baseline values,and wrinkle improvement score increased with the increase in treatment sessions.The Fitzpatrick wrinkle scale score for forehead wrinkles,glabella wrinkles,fishtail lines and neck wrinkles in these subjects after three sessions of treatment significandy differed from that before treatment (all P ＜ 0.01).Significant differences were also observed in the wrinkle improvement score for forehead wrinkles between these subjects after two sessions and one session of treatment (P ＜ 0.01),and observed in that for glabella wrinkles,fishtail lines and neck wrinkles between these subjects after three sessions and one session of treatment (P ＜ 0.05 or 0.01).Side effects were mild with no significant downtime.Conclusion Fractional bipolar radiofrequency may be a safe and effective option for the treatment of wrinkles of the face and neck in individuals with Fitzpatrick skin type Ⅳ-Ⅴ.

Objective To observe the efficacy of percutaneous vertebroplasty (PVP) combined with zoledronic acid in treatment of spinal metastatic carcinoma.Methods Fifty cases of spinal metastatic carcinoma were divided into control group and treatment group by random digits table method with 25 cases each.The control group was given zoledronic acid 4 mg,intervals of 28 d intravenous drip 1 time.The treatment group was given PVP besides zoledronic acid.The visual analog scale score,activity ability score and analgesic usage score after treatment for 3 months were observed and compared.The quality of life was evaluated and the occurrence of relapse of fracture was also recorded.Results After treatment for 3 months,the visual analog scale score,activity ability score and analgesic usage score were (2.00 ± 0.17),(2.12 ± 1.38),(1.47 ± 0.10) scores in treatment group,and (7.84 ± 0.18),(3.21 ± 0.13),(3.30 ± 0.09) scores in control group,and there were significant differences between two groups (P ＜ 0.01 or ＜ 0.05).The occurrence of relapse of fracture was 2 cases (8％,2/25) in treatment group and 9 cases (36％,9/25) in control group,and there was significant difference between two groups (P ＜ 0.05).Conclusions PVP combined with zoledronic acid in treatment of spinal metastatic carcinoma has many advantages such as small incision,short surgery time and rapid relief from pain.It can obviously improve the quality of life,and it is worthy of spreading in the clinic.

AIM: To investigate the changes of current and gene expression of acetylcholine sensitive K~+ channel (K_ ACh ) in chronic human atrial fibrillation (AF) and to evaluate the roles of K_ ACh expression in the occurring and maintenance of AF. METHODS: Acetylcholine sensitive K~+ currents (I_ KACh ) were recorded with the whole-cell patch clamp technique in single atrial myocyte of AF group and normal sinus rhythm group (SR group). The current densities-voltage relations were analyzed. The Kir3.4 mRNA was measured by reverse transcription-polymerase chain reaction. RESULTS: (1) Compared with SR group, acetylcholine sensitive K~+ current densities in AF group were reduced under testing potential between -80 mV and -120 mV . Acetylcholine sensitive K~+ current density was ( -11.665 ?1.027) pA/pF (n=11) in AF group vs ( -19.486 ?0.766) pA/pF (n=11) in SR group at -100 mV testing potential (P

Object To compare the effects of Radix Codonopsis (RC) and Radix Astragali (RA) on ECG of experimental myocardial ischemia rats. Methods The model of myocardia ischemia was made by injection of pituitrin (Pit) in rats. The changes of ECG were observed with three parameters, viz. the heart rate, the locomotions of T wave and S T section. Results Both RC and RA can decrease the run up of T wave in ECG of rats with experimental myocardial ischemic injury in which RC is superior to RA. While RA has stronger effect on the slowering of the heart rate than RC.Conclusion Both RC and RA have protective effect on experimental myocardial ischemic injury induced by Pit.

The study aimed at investigation the effect of the transgenic biocontrol bacteria 308R(pCPP430) on the tomato rhizosphere bacterial communities. Strain 308R (Pantoea agglomerans), an adnascent bacterium isolated from tomato, was a biocontrol bacterium. The recombinant cosmid pCPP430 contained the hrp gene cluster of Erwinia amylovora was transformed into 308R Strain. Transgenic biocontrol bacterium 308R(pCPP430) produced Harpin protein which induce hypersensitive response and disease resistance in plants and, surprisingly, increase plant growth. Two complementary methods, sole-carbon-source utilization tests (SCSU) and ERIC-PCR, were used to compare the characterization of bacterial communities from three groups of tomato roots dipped in sterilized water, 308R suspended liquid and 308R(pCPP430) suspended liquid. The cluster analysis and principal components analysis of the number of colonies from SCSU indicated consistent differences in the rhizosphere of each group. Cluster analysis of SCSU data showed that there were consistent differences in the rhizosphere of each group. The rhizosphere bacteria communities of root dipped with 308R(pCPP 430) and 308R have a relative good replication, but the differences of corresponding replicates in dipped with distilled water was increased by degrees. Cluster analysis of ERIC-PCR fingerprints revealed that most of results (eight in ten) have overlaps between roots dipped in water and those dipped in 308R liquid. The methods used in this study may prove a useful approach for the comparison of bacterial communities.

Objective:To explore the possibility of repairing partial nasal alar defects with individualized design of localized skin flaps.Methods:The clinical data of 38 patients with nasal alar region tumor from October 2015 to June 2019 in Dalian Municipal Central Hospital were retrospectively analyzed, including 5 cases with intradermal nevus, 8 cases with junction nevus, 21 cases with basal cell carcinoma, 3 cases with trichoepithelioma, and 1 case with nasal alar sulcus fistula combined with infection. Surgical treatment with local anaesthesia was applied, and intraoperative freezing pathology was used to confirm the diagnosis and determine the safe margin. There was no nasal alar cartilage infiltration in all patients. The defect areas after resection of nasal alar lesions ranged from 1.0 cm × 1.0 cm to 3.0 cm × 2.5 cm. Local skin flap was aesthetically designed in accordance with the location and size of the nasal alar defect to primarily repair the defect. Among them, 15 cases were repaired with pedicled nasolabial groove flap, 10 cases with modified rhomboid flap, 6 cases with rotatory nasolabial groove flap, 5 cases with V-Y push flap, and 2 cases with double lobe flap.Results:One case had blood transportation obstacle after operation caused by compression and bandaging, 1 case had postoperative infection. Healing of the two cases delayed after treatment, and other patients healed properly. All the flaps survived without facial deformity, and the cosmetic effect was good.Conclusions:The primary repair of the nasal alar defect needs to follow the aesthetic requirements of the nose and face, which varies with diseases and experience of doctors. Flap selection should be individualized to achieve both the purpose of repairing defects and beauty.
