Objective To explore the value of serum microRNAs-145(miR-145)and P53 antibody detection in the evaluation of therapeutic effect and prognosis in the treatment of breast cancer with Long Bei Xiaoyao Powder.Methods Ninety cases of breast cancer patients admitted to Beijing Aerospace General Hospital from January 2020 to January 2021 were selected as the study subjects.The patients were randomly divided into an observation group and a control group by random number table method,with 45 cases in each group.All of the patients in the two groups received individualized comprehensive treatment,and additionally the observation group was treated with Long Bei Xiaoyao Powder.The course of treatment covered three months.Real-time fluorescence quantitative polymerase chain reaction(PCR)method was used to detect serum miR-145 expression level,and enzyme-linked immunosorbent assay(ELISA)was used to detect serum P53 antibody expression level.The differences in the pre-and post-treatment expression levels of serum miR-145 and P53 antibodies in the two groups were compared,the relationship between the serum miR-145 and P53 antibody expression level and the poor prognosis of the patients in the observation group was explored by logistic regression analysis,and receiver operating characteristic curve(ROC)was drawn to analyze the value of the serum miR-145 and P53 antibody detection in the prediction of poor prognosis in the observation group.Results(1)After treatment,the detection value of serum miR-145 in the two groups of patients showed an increasing trend(P＜0.05),while that of the P53 antibody showed a decreasing trend(P＜0.05).The intergroup comparison showed that the detection value of serum miR-145 in the observation group was significantly higher than that of the control group,while the detection value of P53 antibody was significantly lower than that of the control group,the differences being all statistically significant(P＜0.05).(2)In the observation group,the detection value of serum miR-145 in the patients with good prognosis was significantly higher than that in the patients with poor prognosis,and the detection value of serum P53 antibody in the patients with good prognosis was significantly lower than that in the patients with poor prognosis,the differences being all statistically significant(P＜0.05).(3)Logistic regression analysis showed that high expression of miR-145 was a protective factor for the patients with poor prognosis in the observation group,and high expression of P53 antibody was a risk factor for the patients with poor prognosis in the observation group(P＜0.05).(4)The area under the ROC curve(AUC)for the prediction of prognosis of the patients in the observation group by the combination of serum miR-145 and P53 antibody was the largest(0.877,95%CI:0.769-0.985),and its sensitivity and specificity were 93.75%and 93.10%,respectively,with statistically significant differences(P＜0.05).Conclusion Low expression of serum miR-145 and high expression of serum P53 antibody are presented in the breast cancer patients with poor prognosis,and Long Bei Xiaoyao Powder exerts satisfactory therapeutic effect in treating breast cancer,which is conducive to enhancing the expression level of serum miR-145 and reducing the expression level of serum P53 antibody.

BACKGROUNDAlemtuzumab has been used in organ transplantation and a variety of hematologic malignancies (especially for the treatment of B-cell chronic lymphocytic leukemia). However, serious infectious complications frequently occur after treatment. The reason for increased infections postalemtuzumab treatment is unknown at this stage. We explore the effect of alemtuzumab on intestinal intraepithelial lymphocytes (IELs) and intestinal barrier function in cynomolgus model to explain the reason of infection following alemtuzumab treatment.

METHODSTwelve male cynomolguses were randomly assigned to either a treatment or control group. The treatment group received alemtuzumab (3 mg/kg, intravenous injection) while the control group received the same volume of physiological saline. Intestinal IELs were isolated from the control group and the treatment group (on day 9, 35, and 70 after treatment) for counting and flow cytometric analysis. Moreover, intestinal permeability was monitored by enzymatic spectrophotometric technique and enzyme-linked immunosorbent assay.

RESULTSThe numbers of IELs were decreased significantly on day 9 after treatment compared with the control group (0.35 ± 0.07 × 10 8 and 1.35 ± 0.09 × 10 8 , respectively; P < 0.05) and were not fully restored until day 70 after treatment. There were significant differences among four groups considering IELs subtypes. In addition, the proportion of apoptotic IELs after alemtuzumab treatment was significantly higher than in the control group (22.01 ± 3.67 and 6.01 ± 1.42, respectively; P < 0.05). Moreover, the concentration of D-lactate and endotoxin was also increased significantly on day 9 after treatment.

CONCLUSIONSAlemtuzumab treatment depletes lymphocytes in the peripheral blood and intestine of cynomolgus model. The induction of apoptosis is an important mechanism of lymphocyte depletion after alemtuzumab treatment. Notably, intestinal barrier function may be disrupted after alemtuzumab treatment.

Ovarian cancer has become the most lethal gynecological tumor due to the difficulty in early diagnosis,the late stage when diagnosed and the high recurrence rate.Resistance to platinum-based anti-tumor chemotherapy drugs is an important reason for the poor prognosis of ovarian cancer.circular RNA(circRNA)is more stable than mRNA in cells due to its special structure,and it is involved in the regulation of the occurrence,development and chemotherapy resistance of a variety of tumors.circRNA can be used as a competing endogenous RNA(ceRNA)of miRNA to bind to proteins,and regulates the phenotypic polarization of macrophages,it can also be used as an exosomal circRNA to regulate the sensitivity of platinum resistance in ovarian cancer.circRNA is expected to be a new marker of platinum resistance and a new target for the treatment of platinum resistance.In order to further explore the relationship between circRNA and platinum resistance in ovarian cancer,this article summarizes the recent literature related to circRNA and platinum resistance in ovarian cancer.

Purpose: To identify more accurate predictors of upper urinary tract dilatation (UUTD) in neurogenic bladder (NB) children, we studied the relationship among urodynamic parameters at different bladder filling stages, detrusor leak point pressure (DLPP) and UUTD. Methods: A total of 158 children (3–16 years) with NB were included and then divided into 2 groups according to whether their NB diagnosis was complicated with UUTD: the UUTD group (39 patients) and those without UUTD group (control group, 119 patients). The bladder filling phase was divided into 3 equal parts: the early, middle, and end filling stages. The bladder compliance (BC) and detrusor pressure (△Pdet) at each phase and DLPP at the end filling stage were recorded. Results: A BC<8 mL/cm H2O both in the middle and end stages is more specific than a BC<9 mL/cm H2O in the end stage (72%, 73%, vs. 66%), and △Pdet >8 cm H2O in the early stage, 20 cm H2O in the middle stage and 25 cm H2O in the end stage are more sensitive than △Pdet >40 cm H2O in the end stage (82%, 85%, 85%, vs. 49%). A DLPP cutoff value of 20 cm H2O showed higher sensitivity for predicting UUTD than 40 cm H2O. Conclusions Low BC and a high △Pdet in the middle and end filling stages are more accurate factors than classic indicators for predicting UUTD. In addition, a DLPP value of >20 cm H2O in the end bladder filling stage shows high sensitivity.

In recent years, the clinical experts consensuses or guidelines of ankylosing spondylitis (AS)/spondyloarthritis (SpA) have been constantly updated, but to better understand and practice, patient self-participation management is one of the key points to improve the level of diagnosis and treatment. Through questionnaire survey of these patients, we screened out the most concerned issues, and established the AS/SpA patient practice guideline working group with multidisciplinary physicians and patients. Fifteen opinions, as the AS/SpA patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process.

Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndromes in the patients with acute cerebral infarction,and to analyze the correlation of TCM syndromes with collateral circulation,cerebral blood perfusion and prognosis.Methods A total of 300 patients with acute cerebral infarction were selected.All patients underwent head-neck CT angiography(CTA)and CT perfusion imaging(CTP),and then were followed up for 30 days.The prognosis was evaluated by modified Rankin Scale(MRS)score.In addition,the dynamic evolution of TCM syndromes was observed to explore the correlation of TCM syndromes with collateral circulation,cerebral blood flow perfusion in the lesion area and prognosis.Logistic regression analysis was used to explore the influences of TCM syndromes,blood flow perfusion and collateral circulation establishment on stroke outcomes.Results(1)Highest incidences of syndrome elements of phlegm,blood stasis and wind were presented in ACI patients.The syndrome element of qi deficiency was predominated in the patients with anterior/posterior communicating artery opening and extracranial-to-intracranial collateral circulation establishment.On the first day of onset,the incidence of qi deficiency syndrome element in the good collateral circulation group was lower than that in the poor collateral circulation group(P＜0.05).On the 30th day after onset,the incidences of qi deficiency syndrome element and phlegm syndrome element in the good collateral circulation group were significantly lower than those in the poor collateral circulation group(P＜0.01).The results of correlation analysis showed that the score of qi deficiency was negatively correlated with regional cerebral blood volume(rCBV)of region of interest(r=-0.472,P＜0.05),and the score of yin deficiency was positively correlated with rCBV(r=-0.557,P＜0.01)on the first day of onset.The incidence of qi deficiency in the lesion area was relatively high in the patients of decreased rCBV(rCBV＜1.0 score)group(P＜0.01),while the incidence of yin deficiency in the lesion area was relatively high in the patients of elevated rCBV(rCBV＞1.0 score)group(P＜0.05).(2)The distribution of syndrome elements on the first day of onset showed that the incidence of qi deficiency syndrome element in the poor prognosis group was significantly higher than that in the good prognosis group(P＜0.01);on the 30th day after onset,the incidences of qi deficiency syndrome element and phlegm syndrome element in the good prognosis group was significantly lower than those in the poor prognosis group(P＜0.05 or P＜0.01).The incidence of phlegm syndrome element in the good prognosis group was significantly reduced on the 30th day after onset compared with that on the first day of onset(χ2=7.409,P＜0.01),while there was no significant difference shown in the poor prognosis group(P＞0.05).(3)Logistic regression analysis showed that syndrome elements(qi deficiency,phlegm),collateral circulation grading,and rCBV in the lesion area were the independent risk factors for stroke outcomes.Conclusion The acute cerebral infarction patients with poor collateral circulation,decreased blood perfusion and poor prognosis are predominated by qi deficiency syndrome element.Moreover,phlegm syndrome element is presented in the patients with poor prognosis throughout the course of disease.It is indicated that qi deficiency syndrome element and phlegm syndrome element play an important role in the pathogenesis and progression of acute cerebral infarction.

Astragalus membranaceus has the effect of tonifying Qi and solid surface， diuretic support poison， discharging pus and astringent sores to produce muscle. It is not only used for syndromes such as deficiency of lung and temper， deficiency of spleen and diarrhea， but also for stroke， chest obstruction and other diseases. Due to the complex chemical composition and diverse pharmacological effect of Astragalus membranaceus， and the main role in invigorating qi and activating blood circulation has not been clarified. Astragaloside Ⅳ is one of its main active ingredients. In recent years， more and more studies on Astragaloside Ⅳ have been conducted at home and abroad. It has been reported that it has the medicinal value of enhancing immune function， strengthening heart and lowerin blood glucose， diuresis， anti-aging and anti-fatigue， et al， and has extensive pharmacological activity. Among them， the role of cardiovascular and cerebrovascular diseases in particular has attracted increasing attention. Cardiovascular and cerebrovascular diseases are ischemic or hemorrhagic diseases occurring in the heart， brain and systemic tissues due to blood viscosity， atherosclerosis， hypertension， hyperlipidemia， etc.， including cardiovascular and cerebrovascular diseases. Such diseases are a serious threat to mankind and are the leading cause of death worldwide. At present， western medicine is the main treatment， with many adverse reactions and poor long-term prognosis. TCM believes that the imbalance of qi and blood is the basic pathogenesis of this kind of disease. Qi deficiency and blood stasis are more common.At present， Astragaloside Ⅳ in the treatment of cardiovascular and cerebrovascular diseases in a number of studies， and achieved some results， but this review in recent years， Astragaloside Ⅳ in the treatment of cardiovascular and cerebrovascular diseases play the pharmacological activity， in order to explore whether Astragaloside Ⅳ is the main role of astragalus qi to find a theoretical basis for material basis， but also for the innovation of traditional Chinese medicine drug research and development of theoretical basis and practical guidance.

OBJECTIVETo assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form (IPAQ-L) in urban community-dwelling adults in Hanghzou, China.

METHODSA total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval. Half of the subjects wore pedometers during the first 7 days. Test-retest reliability was examined by comparing the first (Day 1) and the second (Day 9) survey of IPAQ-L. Criterion validity was assessed by comparing IPAQ-L with pedometer data.

RESULTSModest to good test-retest reliability was found with intraclass correlation coefficients of 0.67 for total PA, 0.37 to 0.73 for specific dimensions, and 0.56 to 0.71 for different intensities of PA. Total PA measured by IPAQ-L was moderately correlated with exercise levels (partial r = 0.27, P = 0.020) and walking distance (partial r = 0.31, P = 0.007), which were measured by a pedometer, after adjusting for gender, age, educational attainment and employment status.

CONCLUSIONOur results indicate that the IPAQ-L is a reliable and validated measure for assessing physical activity levels in this population and possibly the adult population in other mainland Chinese cities.

BackgroundFunctional dyspepsia (FD) is a common upper gastrointestinal disorder worldwide, but the current treatments for FD are still unsatisfactory. The aims of this study were to investigate the efficacy and safety of Qi-Zhi-Wei-Tong granules in patients with postprandial distress syndrome (PDS)-predominant FD.

MethodsThe study was conducted as a randomized, double-blinded, multicenter, placebo-controlled design in 197 patients with PDS. All participants received placebo treatment for 1 week. Patients whose total symptom score decreased by <50% after the placebo treatment were recruited into the 4-week treatment period, in which they were randomly assigned to be treated with either Qi-Zhi-Wei-Tong granules or placebo. The patients were then followed for 2 weeks without any treatment. Dyspeptic symptoms were scored at weeks 2 and 4 during the random treatment period and 2 weeks after the treatment. Anxiety and depression symptoms were also scored and compared.

Results(1) The total effective rates in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 during the random treatment period and 2 weeks after treatment were all significantly higher than those in the placebo group (38.82% vs. 8.75%, P < 0.001; 69.14% vs. 16.25%, P < 0.001; 77.65% vs. 21.25%, P < 0.001). (2) The total dyspeptic symptoms scores in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 and 2 weeks after treatment were significantly lower than those in the placebo group. (3) The severity and frequency of each dyspeptic symptom at weeks 2 and 4 and the follow-up period were all significantly lower than those in the placebo group. (4) The anxiety scores in the Qi-Zhi-Wei-Tong granules group were significantly lower than those in the placebo group. (5) Qi-Zhi-Wei-Tong granules did not have more adverse effects than the placebo.

ConclusionQi-Zhi-Wei-Tong granules offer significant symptomatic improvement in PDS with no more adverse effects than placebo.
