ObjectiveA qualitative analysis method was established for the composition of Astragali Radix（AR） before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice（ARR）， the structures of their major compounds were deduced and identified， and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detect the samples of AR and ARR in positive and negative ion modes， respectively. The compounds were analyzed and identified through self-constructed databases， literature， and reference standards， etc. And the data were analyzed by chemometrics， in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR， including 41 flavonoids， 19 terpenoids， 26 organic acids， 8 amino acids， 5 nucleotides， 5 carbohydrates and 19 other compounds. Among them， there were 95 common components in both， 18 unique components in AR， and 10 unique components in ARR. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying， and a total of 26 constituents with differences in the content were screened out， including L-canavanine， L-pyroglutamic acid， L-phenylalanine， cis-caffeic acid， and malonylastragaloside Ⅰ. Among them， 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids， terpenoids， and organic acids， and analyzes the components with significant differences in content between the two in combination with chemometrics， and the differential components are dominated by amino acids， organic acids and terpenoids， which can provide reference for the subsequent quality control and material basis research.

Objective To understand the awareness and willingness of primary medical staff in Songjiang District, Shanghai towards human papillomavirus (HPV) and its vaccines, and to provide references for improving the vaccination willingness of HPV vaccine and primary prevention of cervical cancer. Methods From July to August 2023, a questionnaire survey was conducted among the in-service medical staff in 17 community health service centers in Songjiang District, Shanghai, using the random sampling method. Descriptive analysis, χ² test and logistic regression were used for statistical analysis. Results A total of 951 valid questionnaires were collected during the survey. The awareness rate of HPV among medical staff was 92.74%, and the awareness rate of HPV vaccine was 93.38%. The maximum score for HPV knowledge was 6 points, with an average score of (3.99±1.34) points. The maximum score for HPV vaccine knowledge was 10 points, with an average score of (5.63±1.61) points. 881 (92.64%) medical staff were willing to receive or recommend HPV vaccination. Multivariate analysis showed that concerns about being infected with HPV (OR=2.648, 95% CI: 1.459-4.806), qualified score on HPV vaccine knowledge (OR=1.717, 95% CI: 1.012-2.912), high price burden of HPV vaccine (OR=0.343, 95% CI: 0.157-0.746), and concerns about side effects of vaccination (OR=0.443, 95% CI: 0.243-0.805) were the influencing factors for medical staff's willingness to vaccinate. Conclusion There is insufficient knowledge of HPV and its vaccines among primary medical personnel in Songjiang District, Shanghai. It is necessary to strengthen the continuing education of medical personnel through multiple channels, supplement the HPV-related knowledge system, and eliminate their concerns about vaccines.

miR-135 is a highly conserved miRNA in mammals and includes miR-135a and miR-135b.Recent studies have shown that miR-135b is a key regulatory factor in cardio-cerebrovascular diseases.It is involved in regulating the pathological process of myocardial infarction,myocardial ischemia/reperfusion injury,cardiac hypertrophy,atrial fibrillation,diabetic cardiomyopathy,atherosclerosis,pulmonary hyperten-sion,cerebral ischemia/reperfusion injury,Parkinson's disease,and Alzheimer's disease.Obviously,miR-135b is an emerging player in cardio-cerebrovascular diseases and is expected to be an important target for the treatment of cardio-cerebrovascular diseases.However,the crucial role of miR-135b in cardio-cerebrovascular diseases and its underlying mechanism of action has not been reviewed.Therefore,in this review,we aimed to comprehensively summarize the role of miR-135b and the signaling pathway mediated by miR-135b in cardio-cerebrovascular diseases.Drugs targeting miR-135b for the treatment of diseases and related patents,highlighting the importance of this target and its utility as a therapeutic target for cardio-cerebrovascular diseases,have been discussed.

Objective To observe the effect of Tongbi decoctionon for the changes of the endothelial function and hemorheology in patients with coronary heart disease. Methods A total of 90 patients with angina pectoris were divided into the observation group and the control group according to the random number table method, with 45 in each group. The control group was given routine clinical treatment, and the observation group was treated with Tongbi decoction on the basis of the control group. After treated for 4 weeks, the pain severity of angina pectoris was observed before and after treatment, and the frequency and duration of angina pectoris were recorded. The levels of serum vascular endothelin (ET) and endothelin (VEGF) were measured by ELISA. The serum NO was measured by nitrate reductase method, and whole blood viscosity and plasma viscosity were measured by blood viscometer. The hematocrit was measured by hematocrit analyzer and optical density method. The erythrocyte aggregation index was measured, and the fibrinogen level was measured by heating precipitation method. And the clinical efficacy was evaluated. Results After treatment, the total effective rate was 93.3％ (42/45) in the observation group and 77.8％ (35/45) in the control group, and there was significant difference between the two groups (Z=-3.164, P=0.002). After treatment, the score of angina pain (0.62 ± 0.05 vs. 1.17 ± 0.14, t=5.733) , the frequency of angina attack (3.62 ± 0.43 times/week vs. 5.02 ± 0.64 times/week, t=5.042), the duration of angina attack (3.17 ± 0.42 minutes/time vs. 4.06 ± 0.51 minutes/time, t=4.781) in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the levels of VEGF and NO in the observation group were significantly higher than those in the control group (t value was 5.892, 5.347, all Ps<0.05), and ET was significantly lower than that in the control group (t=4.926, P=0.037). After treatment, the whole blood viscosity, plasma viscosity, hematocrit, aggregation index and fibrinogen levels in the observation group were significantly lower than those in the control group (t values were 4.832, 4.233, 5.031, 4.136, 4.531, all Ps<0.05). Conclusions The application of Tongbi decoction can improve the endothelial function of patients with angina pectoris, adjust the hemorheological indexes and relieve the symptoms related to angina pectoris.

Objective To investigate the clinical value of 99Tcm-methoxyisobutylisonitrile (MIBI) double-phase imaging in differential diagnosis of bone lesions in tumor patients,which was indefinite in 99Tcm-methylene diphosphonate (MDP) bone imaging,and evaluate the correlation between 99Tcm-MIBI imaging and chemotherapy efficacy.Methods Fifty-two tumor patients (23 males,29 females,mean age 58 years) with bone isolated lesions(≤3) found by 99Tcm-MDP bone scintigraphy was enrolled from June 2014 to November 2015.Since the results of 99Tcm-MDP imaging were indefinite,99Tcm-MIBI double-phase (10 min and 30 min after injection of 99Tcm-MIBI) SPECT/CT imaging was then performed within 1 week.The final diagnosis was made according to results of more than two imaging modalities (CT,MRI,PET/CT) and/or follow-up (≥6 months).The diagnostic efficacy of 99Tcm-MIBI SPECT/CT imaging was calculated.The clinical dataof chemotherapy were also collected.Patients with bone metastasis were grouped as the treatment response.Retention index (RI) of metastatic lesions was calculated and compared between different groups using two-sample t test.The relationship between RI and chemotherapy efficacy was investigated by Spearman correlation analysis.Results A total of 12 benign lesions and 84 malignant lesions were eventually diagnosed.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and Youden index of 99Tcm-MIBI imaging were 96.43％(81/84),83.33％(10/12),97.59％(81/83),76.92％(10/13),and 0.80,respectively.The RI was statistically different between complete remission (CR)+partial remission (PR) group and stable disease (SD) + progressive disease (PD) group:-0.142± 0.036 vs-0.384± 0.067 (t =2.367,P＜0.05).The RI of 99Tcm-MIBI in bone metastases was positively correlated with the chemotherapy efficacy (rs =0.78,P＜0.01).Conclusions 99Tcm-MIBI imaging is helpful in differential diagnosis of bone lesions with indefinite diagnosis by 99Tcm-MDP bone imaging in tumor patients.99Tcm-MIBI RI of bone metastasis may predict the therapeutic response of chemotherapy efficacy.

OBJECTIVE:To provide reference for strengthening the safety of the combination use of CYP3A4 inhibitors with statins in clinical treatment. METHODS:30 cases per month(totally 300 cases)(the hospitalization time was more than 10 days) discharged from the cardiology department of a third-level class A hospital during Jan. to Oct. 2013 were selected randomly,and statistical analysis was made into general information of patients,whether to use statins and CYP3A4 inhibitor,and whether to monitor safety indicators of liver and kidney function and creatine kinase. RESULTS:Totally 291 patients were treated with statins with a total use rate of 97%,including 265 cases of atorvastatin and 11 cases of simvastatin. The CYP3A4 inhibitors were com-bined with amlodipine,diltiazem,verapammy,amiodarone,Ginkgo biloba leaf,fenofibrate and clarithromycin,etc.,and 162 (59%) patients were given the combination use of simvastatin or atorvastatin with CYP3A4 inhibitors. But the liver and kidney function,creatine kinase and other safety indicators were not monitored by laboratory examination during medication. CONCLU-SIONS:Atorvastatin and simvastatin are used commonly in patients with cardiovascular disease,and the combination use rate with CYP3A4 inhibitor is relatively higher and needs long-term medication,drug dosage should be limited according to the direction of instructions and the adverse reactions induced by drug interactions should be noticed to strengthen medication monitor and education for patients.

Objective To investigate the long-term curative effect of the radiotherapy combined uterine arterial interventional chemoembolization for cervical cancer.Methods Records of 632 patients with cervical cancer stage Ⅱ-Ⅳa proved by pathology in Lanzhou Command General Hospital from January 1st,1999 to August 31st.2009 were retrospective analysed.One hundrand and twenty-six cases of them were treated with radical radiothempy combined uterine arterial interventional chemoembolization(arterial chemoembolization+radiotherapy group).506 cases of them were treated with radical radiotherapy only (radiotherapy group);the evaluation of the late radiation injury was done,according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer(RTOG/EORTC)advanced radiation injury criteria.Prognosis and complications were compared between two groups,relative risk factors of radiothempy complications were identified by method of logistic regression.Results (1)Survival:the total survival mtes of 1-year,2-year,5-year and 8-year were 94.4%,82.3%,48.8%,29.1%,respectively.The survival rates of arterial chemoembolization+radiotherapy group were 96.0%.82.1%,37.2%,25.7%,while the survival rates of radiotherapy group were 94.1%,80.8%,51.1%,31.5%,in which there were significant differences between two groups (x2 = 0.009, P= 0.993; x2 =0. 158, P =0.691;X2 =11. 197,P=0. 001;x2 =9. 649,P =0.002). During the follow-up period, the rate of recurrence and metastasis in arterial chemoembolization + radiotherapy group were 77. 0% (97/126), while 73. 3% (371/ 506) in radiotherapy group ( x2 = 0. 705,P = 0. 401). (2) Radiotherapy complications and relative risk factors; the total incidence of tardive bladder injury higher than RTOG/EORTC stage II was 5.5% (35/632), while it was 11. l%(14/126)in arterial chemoembolization + radiotherapy group, 4.2% (21/506) in the radiotherapy group(x2 =9.344,P =0.002). The results of logistic regression showed that the uterine arterial interventional chemoembolization was relative risk factors of the tardive bladder injury ( x2 =6. 440, OR = 2. 869,P=0. 011). Conclusions Compared with the simple radiotherapy, there are a similar short-term survival rate and significant poor 5-year, 8-year survival rate in the patients treated with the uterine arterial interventional chemoembolization combined with radiotherapy, which also may be strong dangerous factor for the occurrence of tardive bladder injury. The results shown that the uterine arterial interventional chemoem bolization do not recommend to be routine adjuvant therapy for the radical radiotherapy of cervical cancer.
