OBJECTIVE:To study the effect of Typhae pollen decoction on isolated uterine smooth muscle(USM)contraction of rats at postconceptual stage. METHODS:16 Wistar rats at postconceptual stage were selected and USM strips were isolated. T. pollen decoction 0(blank control),2,4,8 and 12 mg(medicinal material)/ml were added respectively;the effects of T. pollen de-coction on USM strips contraction were observed,and mean tension,duration of contraction and frequency were measured and re-corded. The effects of T. pollen decoction on USM strips contraction were investigated after pretreatment of prostaglandin synthase inhibitor indometacin(1×10-7 mol/ml)and calcium channel blocker verapamil(1×10-7 mol/ml);USM tension,duration of contrac-tion and frequency were measured and recorded. RESULTS:Compared with blank control group,T. pollen decoction 4,8 and 12 mg(medicinal material)/ml could increase USM tension,duration of contraction and frequency(P<0.05);after added verapamil and indometacin,T. pollen decoction decreased USM tension,shortened duration of contraction and decreased frequency (P<0.05). CONCLUSIONS:T. pollen decoction can strengthen USM strips contraction,and the effect is inhibited by prostaglandin syn-thase inhibitor and calcium channel blocker.

OBJECTIVETo observe the effect of electroacupuncture (EA) combined with ultraviolet therapy on herpes zoster at the acute stage and the impacts on serum interleukin 2 (IL-2), interleukin 6 (IL-6) and interleukin 10 (IL-10) in the patients.

METHODSThirty-four patients of herpes zoster were randomized into a medicine group and a combined therapy group, 17 cases in each one. In the medicine group, the intravenous drops with acyclovir injection, muscular injection with cobamamide and the topical with acyclovir ointment were applied. Additionally, TDP was radiated locally. In the combined therapy group, on the basis of the treatment as the medicine group, EA and ultraviolet therapy were supplemented. The duration of treatment was 10 days in the two groups. Before and after treatment, blister relief, incrustation time and the visible analogue scale (VAS) were recorded in the two groups. The clinical efficacy was assessed in the two groups and the levels of serum IL-2, IL-6 and IL-10 were determined in the two groups.

RESULTSIn the combined therapy group, the time of blister relief and incrustation was earlier apparently than that in the medicine group (both P<0.05). VAS score after treatment were reduced as compared with that before treatment in the two groups (both P<0.01), and the reducing amplitude in the combined therapy group was larger than that in the medicine group (P<0.01). The total effective rate was 94. 1% (16/17) in the combined therapy group, higher than 76.4% (13/17) in the medicine group (P<0.05). After treatment, IL-2 levels were increased as compared with those before treatment in the two groups (both P<0.05), the levels of IL-6 and IL-10 were reduced obviously as compared with those before treatment in the two groups (all P<0.01). After treatment, the levels of IL-6, IL-10 were reduced much more apparently in the combined therapy group as compared with those in the medicine group (both P<0.05).

CONCLUSIONEA combined with ultraviolet irradiation more rapidly and effectively relief the symptoms of herpes zoster, significantly relief pain, shorten the duration of sickness, improve the body immunity and reduce nerve injury.

Objective To correlate dynamic parameters at contrast enhanced CT and interstitial fibrosis grade of non-small cell lung cancer (NSCLC). Methods Twenty-nine patients with NSCLC were evaluated by multi-slice CT. Images were obtained before and at 20,30,45,60,75,90,120,180,300,540,720,900 and 1200 s after the injection of contrast media, which was administered at a rate of 4 ml/s for a total of 420 mg I/kg body weight. Washout parameters were calculated. Lung cancer specimens were stained with hematoxylin-eosin stain and collagen and elastica double stain. Spearman test was made to analyze correlation between dynamic parameters and interstitial fibrosis grade of tumor. Results Twentynine NSCLC demonstrated washout at 20 min 12. 1 (0. 32-58.0 ) HU, washout ratio at 20 minutes 15.3% (0. 3%-39.2% ), slope of washout at 20 minutes 0. 0152 %/s ( 0. 0007%/s-0. 0561%/s ).Interstitial fibrosis of 29 lesions was graded as grade Ⅰ (10), grade Ⅱ (14) and grade Ⅲ (5). There were significant correlation between washout at 20 min ( r = - 0. 402, P ＜ 0. 05 ), washout ratio at 20 min ( r =-0.372,P＜0.05), slope of washout ratio (r = -0.459,P ＜0.05) and interstitial fibrosis grade in tumors. Conclusion NSCLC washout features at dynamic multi-detector CT correlates with interstitial fibrosis in the tumor.

Objective To conduct a Meta?analysis to compare the safety and short?term efficacy of laparoscopic assisted distal gastrectomy (LADG)and open distal gastrectomy(ODG)in D2 radical surgeries for locally advanced distal gastric cancer. Methods The literatures from Janurary,1990 to August,2014 on the evaluation of safety and short?term efficacy of LADG versus ODG in D2 radical surgeries for locally advanced distal gastric cancer were collected. The quality of the enrolled articles was evaluated and the software Revman 5.2 was adopted to analyze the cura?tive effect. Results Totally 25 articles met the inclusion criteria,including 5 044 patients with treatment of D2 radical surgeries for locally advanced distal gastric cancer. There was no significant difference in the cleaning number of lymph nodes between LADG and ODG in patients undergoing D2 radical surgeries for locally advanced distal gastric cancer. The operation time was longer for LADG than ODG,but the postoperative evaluation in?dexes such as the intraoperative blood loss and the short?term efficacy of LADG were superior to ODG. Conclusion In the treatment of locally ad?vanced distal gastric cancer,there were differences in the safety and short?term efficacy between LADG and ODG,and surgeons should give concern to these differences in clinical practice to select appropriate surgical approaches. Further research is still needed to explore the long?term efficacy.

Objective:To determine the prevalence of Helicobacter pylori (Hp) infection in orthotopic liver transplantation (LT) recipients, and to study the efficacy and safety of Hp eradication therapy.Methods:13C-urea breath test was carried out between July 2018 and October 2019. There were 104 males and 26 females with an average age of 52.1 year for these LT recipients who were regularly followed-up in the Organ Transplant Center, the Affiliated Hospital of Qingdao University. Propensity scoring was used to match age and gender in a ratio of 1∶3. A healthy group of individuals consisting of 299 males and 91 females, with an average age of 51.8 years, were selected as the control group also in a ratio of 1∶3. All patients underwent 13C-urea breath test to evaluate Hp infection and results of quadruple therapy. Results:The prevalence of Hp infection among the LT recipients was 18.5%(24/130) which was significantly lower than the control group 36.4% (142/390) (χ 2=14.400, P<0.001). Among the recipients who received LT and 13C-urea breath test for less than 1 year, 1-3 years and more than 3 years, the prevalences of Hp infection were 14.3% (6/42), 17.8%(8/45) and 23.3%(10/43), respectively. Although the prevalence of Hp showed a gradually increasing trend, no correlation between Hp infection and duration from LT was observed (χ 2=1.321, P=0.517). Seventeen Hp positive recipients underwent Hp eradication therapy. The success rate of Hp eradication was 100.0%(17/17). Immunosuppressant concentration was monitored regularly in 10 patients. During Hp eradication, the blood concentration of immunosuppressant increased from 1.7 to 3.6 times, and the drug dosage was reduced to one half to one third of what it was before Hp eradication. Seven of these 17 recipients suffered from adverse effects caused by increased levels of blood concentration of immunosuppressants, including headache, hypertension, insomnia and irritability. Normal liver and kidney functions were observed during eradication. Conclusion:In this study, the prevalence of Hp infection among liver transplant recipients was 18.5%. The success rate of Hp eradication was 100% using bismuth-containing quadruple therapy. The dosage of immunosuppressant required to be monitored, and if necessary, adjusted during eradication to reduce adverse side effects.

Objective:To investigate the effect of a 2-year resistance and aerobic training on reducing the risk of cardiovascular disease in patients with prediabetes.Methods:A total of 248 patients with prediabetes were enrolled from Chinese and Western Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from January to April 2014, and Danyang People′s Hospital and The First Affiliated Hospital of Guangxi Medical University from May to December 2014.Based on random number table method, the patients were divided into 3 groups: the resistance training group (RT group, 82 cases), the aerobic training group (AT group, 83 cases) and control group (83 cases). Participants in the RT group and the AT group underwent a total of 24 months of exercise training. Changes in indicators (blood glucose,blood lipid, etc.) at baseline and the end of 12 and 24 months among the groups were compared.Results:After intervention, glycosylated hemoglobin (HbA1c), low density lipoprotein cholesterol (LDL-C), blood pressure and homeostasis model 2 insulin resistance index (HOMA2-IR) in the RT and AT groups tended to decrease, and the steady state model 2 β cell function index (HOMA2-β) tended to increase. At the end of 24 months, HbA1c [5.80 (5.43, 6.20) %, 5.70 (5.50, 6.00)% vs. 6.20 (5.70, 6.60) %, all P≤ 0.01], LDL-C [3.07 (2.69, 3.58) mmol/L, 2.97 (2.62, 3.95) mmol/L vs. 3.21(2.54, 3.78) mmol/L, all P<0.05] and HOMA2-IR [0.96 (0.82, 1.47), 1.20 (0.99, 1.43) vs. 1.34 (1.09, 1.51), all P<0.05] were significantly decreased in the RT and AT groups than in the control group. In addition, HOMA2-β [84.50 (60.55, 107.33), 93.00 (78.60, 119.75) vs. 53.40 (37.70, 80.40), all P = 0.001] was significantly increased in the AT and RT groups compared with that in the control group. There were no significant differences in triglyceride (TG) and high-density lipoproteincholesterol (HDL-C) levels between the training groups and the control group (all P>0.05). After adjusting for age, sex and blood pressure, the cardiovascular risk of prediabetes was significantly reduced in RT ( P =0.017) and AT groups ( P =0.018). The Cox regression analyses showed that both the resistance training (HR=0.419, 95 %CI =0.415-0.942, P=0.037) and the aerobic training ( HR=0.310, 95 %CI=0.447-0.866, P=0.026) were protective factors for cardiovascular disease in prediabetic patients after adjustment of age, sex, statins, body mass index and waist-to-hip ratio, which reduced the risks of cardiovascular disease in prediabetic patients by 58.1% and 69.0%, respectively. Conclusions:Two years of aerobic and resistance training interventions have obvious advantages on glycemic and insulin resistance control in prediabetes patients. The resistance training can reduce the risk of cardiovascular disease, and it is, thus, recommended for prediabetic patients without obvious exercise contraindications.

Objective To evaluate the psychological distress of patients with retinal detachment and analyze its causes and related factors. Method We adopted a general information questionnaire and psychological distress thermometer (DT) to do a cross-sectional survey among patients undergoing retinal detachment reduction surgery between February 2016 and May 2017 in West China Hospital in Sichuan Province. Results The average score of psychological pain in the patients with retinal detachment was 4.3 ±2.0. Significant psychological distress was observed in 83 cases, which accounted for 67.5% (DT score was greater than 4). The top 5 factors for the psychological distress caused by the retinal detachment were edema, physical activity restricted, worry, bathing/dressing, and sleep problem. Multivariate linear regression analysis showed that age, sports, time of retinal detachment and combination of chronic diseases had an effect on psychological pain score (all P＜0.05). Conclusions The psychological distress of patients treated in retinal detachment reduction surgery is severe, and the physical problems are the main causes of psychological distress. In order to effectively prevent the emergence of psychological problems, psychological intervention measures should be taken in patients at young age, long time of retinal detachment, doing sports, and combination with other chronic diseases.

Objective To describe the current situation of pre-hospital delay and health belief in patients with colorectal cancer and explore the relationship between them. Methods With convenient sampling methods,totally 385 patients with colorectal cancer were recruited from January to June 2016. Patients with colorectal cancer were investigated using a general data survey questionnaire, visit situation questionnaire and the Champion Health Belief Model Scale. Results The median pre-hospital delay time was 3.00 months.The rate of pre-hospital delay was 43.1%(166/385). The score of the overall health belief was (119.52 ± 12.62) points. The two dimensions of"perceived susceptibility and perceived severity" scored lower, and the two dimensions of "health motivation and perceived therapeutic benefits" scored higher. The health belief was negatively correlated with the pre- hospital delay among colorectal cancer patients (r=- 0.737, P<0.01). Conclusions Pre-hospital delay occurred among patients with colorectal cancer is severe. Patients with a higher level of health belief have shorter pre-hospital delay.It′s important to improve the level of health belief of"perceived susceptibility and perceived severity"and reduce the time of pre-hospital delay to improve outcomes in patients with colorectal cancer.

[ ABSTRACT] AIM:To investigate the depressant effect of FK228 combined with rapamycin on the human breast cancer cell line MCF-7 and MDA-MB-435.METHODS:FK228, a new histone deacetylase inhibitor, and rapamycin, the specific inhibitor of the mammalian target of rapamycin ( mTOR) protein, were used in the study.MCF-7 cells and MDA-MB-435 cells were exposed to different concentrations of FK228 and rapamycin.The inhibitory rate of cell growth was de-termined by SRB assay.Combination index ( CI) was used to evaluate the interaction between FK228 and rapamycin.The expression of the apoptotic proteins, cycle proteins and nucleic acid proteins were detected by Western blotting.The cell cycle was analyzed by flow cytometry.RESULTS: Both FK228 and rapamycin showed growth inhibitory effects on the breast cancer cell lines in a time-and dose-dependent manner.CI of the 2 drugs was less than 1 when the inhibitory rate of the cell growth was 50%effective dose (ED50)~ED70, indicating a synergistic effect.The combination therapy of FK228 with rapamycin increased the apoptotic proteins, and induced the down-regulation of phosphorylated Akt and over-expres-sion of caspase-3 compared with a single use of the drugs.The combination therapy of FK228 with rapamycin reduced the cycle proteins, and the cell cycle was arrested in G2/M.The levels of phosphorylated H2AX and acetylated H3 were ob-viously increased after combination therapy.CONCLUSION:The combination therapy of FK228 with rapamycin inhibits the cell proliferation and increases apoptosis with a synergistic effect, which may become a new trend for treating endometri-al cancer.
