Objective:To compare the efficacy and safety of broad-band intense pulsed light (OPT-IPL) versus narrow-band intense pulsed light (DPL) in the treatment of rosacea-associated erythema and telangiectasia.Methods:Fifty-four rosacea patients who received treatment with intense pulsed light were collected from Laser Department, Hospital of Dermatology, Chinese Academy of Medical Sciences from October 2016 to December 2019, and clinical data were retrospectively analyzed. Their age ranged from 19 to 56 years, and disease duration ranged from 0.2 to 10 years. Of the 54 patients, 22 were treated with OPT-IPL, and 32 were treated with DPL. All patients completed at least one session of treatment and follow-up. Therapeutic efficacy was evaluated by using clinician erythema assessment (CEA) and physician global assessment (PGA) scales, and adverse reactions were assessed. A generalized linear mixed model was used to analyze differences in CEA and PGA scores among different groups and treatment sessions.Results:In the OPT-IPL group, 22, 17 and 10 cases completed 1, 2 and 3 sessions of treatment respectively, with the energy fluence being 16.57±1.21 J/cm 2. In the DPL group, 32, 25 and 16 cases completed 1, 2 and 3 sessions of the treatment respectively, with the energy fluence of 9.76±0.61 J/cm 2. Before the start of treatment and after 1, 2 and 3 sessions of treatment, the CEA scores were 2.38±0.84, 2.29±0.75, 1.94±0.66 and 1.90±0.66 respectively in the OPT-IPL group, and 2.25±0.77, 2.16±0.77, 1.84±0.81 and 1.47±0.81 respectively in the DPL group. As far as the CEA score was concerned, there was no interaction between the groups and treatment sessions ( F=0.57, P=0.638) , and no significant difference between the OPT-IPL group and DPL group ( F=0.84, P=0.360) , but a significant difference was observed among different sessions of treatment ( F=17.90, P< 0.001) , and the CEA score gradually decreased along with the increase of treatment sessions compared with that before treatment (all P< 0.05) . After 1, 2 and 3 sessions of treatment, the PGA scores were 0.39±0.71, 0.82±0.92 and 0.55±0.80 respectively in the OPT-IPL group, and 0.61±0.77, 1.34±1.09 and 1.53±1.38 respectively in the DPL group. As far as the PGA score was concerned, there was no interaction between the groups and treatment sessions ( F=1.62, P=0.202) , and no significant difference between the OPT-IPL group and DPL group ( F=3.93, P=0.050) , but there was a significant difference among different sessions of treatment ( F=19.33, P< 0.001) . Compared with the PGA score after 1 session of treatment, the PGA score gradually increased along with the increase of treatment sessions (all P< 0.001) . After treatment, no adverse reactions, such as blisters and crusts, occurred in either of the 2 groups, and there was no significant difference in the incidence of pigmentation, erythema aggravation, papules or increase in papule count between the 2 groups (all P> 0.05) . Conclusion:The efficacy and safety of DPL are comparable to those of OPT-IPL in the treatment of rosacea-related erythema and telangiectasia, but lower energy fluence is required.

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.

In the treatment of primary epilepsy, Traditional Chinese Medicine (TCM) compounds and the combination of TCM and Western medicine with acupuncture and moxibustion, massage, acupoint embedding and other therapies are used most. The combined application of different therapies could enhance the curative effect, which could effectively control the frequency of the outbreak of this disease, reduce the adverse reactions of drugs, and further improve the quality of life of patients. In recent years, the number of TCM clinical studies related to this disease has increased, but most of the studies have a small sample size, unclear long-term efficacy, few double-blind trials, and unclear random methods. In addition, the criteria of syndrome classification and curative effect of primary epilepsy need to be unified.

Objective: To investigate the effect and mechanism of emodin (EMO) on human pancreatic cancer cell line BxPC-3 in vivo. Methods: After the pancreatic cancer model in nude mice was established, the mice were divided into four groups: control group (NS 0.2mL/d by i.p. injection), EMO group (EMO 40mg?kg-1?d-1 by i.p. injection), and Gemcitabine (GEM) group (GEM 80mg/kg, twice/week by i.p. injection) with 8 mice each group. After 2 weeks of administration, the mice were sacrificed, detected the body-weight change of nude nice before and after the experiment, and recorded the growth inhibition rate of tumor (TGI). Immunohistochemical (IHC) staining for ki-67 and terminal deoxynucleotidyl transferase-mediated nicked labeling assay (TUNEL) were undertaken to detect the cell proliferation and cell apoptosis in tumor tissue in xenograft nude mice. Results: The inter-group comparisons in body-weight of nude mice showed no significant difference in comparing group NS(27.0?1.64)g with group EMO(25.1?1.58)g and GEM(25.6? 1.47)g.The EMO group was 38.46%, the GEM group was 44.23%. The inter-group comparisons in immunohistochemical analysis of ki-67 showed significant difference in comparing group NS IOD(219.5?17.98) with group EMO IOD(146.6? 11.57)and GEM IOD(139.5?12.55), (P

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

Objective:To investigate the effect of perineural invasion (PNI) on patients with early squamous cell carcinoma of the tongue (ESCCT) and the controversial issues related to PNI's effect on loco-regional recurrence, cervical lymph node metastases, and prognosis. Methods:Data of 156 patients with ESCCT were analyzed. Two subgroups comprising 40 patients each were investigated. One was PNI-positive subgroup, and the other subgroup was consisted of patients with PNI-negative carcinomas. These patients had similar histopathological characteristics and were randomly selected from the total number of cases. The relationship among the prevalence of PNI, loco-regional recurrence, cervical lymph node metastases, and prognosis was analyzed. Results:PNI was significantly correlated with high cervical lymph node metastases and poor 5-year survival rates (P=0.045 and P=0.034, respectively) but not with local recurrence (P=0.531). Elective neck dissection was considerably associated with a low risk of regional recurrence among the PNI-positive ESCCT patients (P=0.001). Conclusion:PNI should be considered as a predictor for high cervical lymph node metastases and poor 5-year survival of early tongue squamous cell carcinoma. Elective neck lymph node dissection should be performed among patients with PNI-positive early tongue squamous cell carcinoma.
