Objective To investigate the clinical effect of methotrexate combined with dilatation and curettage on the treatment of cesarean section scar pregnancy and the effect on HCG (chorionic gonadotropin). Methods 130 cases with cesarean section scar pregnancy admitted in Taizhou hospital from January 2016 to March 2017 were randomly divided into two groups. The control group wasreceived dilatation and curettage. The study group was given methotrexate combined with dilatation and curettage.The effect and the influence to HCG in the two groups were compared. Results The effective rate in the study group was significantly higher than that in the control group (P<0.05). There was no significant difference in HCG level between the two groups before treatment. The levels of HCG in the study group were significantly lower than that in the control group (P<0.05). Conclusion Methotrexate combined with curettage on the treatment of cesarean scar pregnancy, can improve the therapeutic effect, reduce postoperative bleeding and hospitalization time, reduce the level of HCG.

Objective To investigate integrated status of community inpatients with type 2 diabetes mellitus.Methods 240 cases of type 2 diabetic patients in the Zhangjiagang Aoyang Hospital were included in the study from May 1,2007 to Dec 31,2008.A uniform questionnaire was applicated.Gender,disease duration,age,academic qualifications,occupation,education,height,weight,waist circumference,hip,relevant medical history and so on were collected.Results The onset age of inpatients with type 2 diabetes was (48.91 ± 12.38),onset age of male was(46.32 ±12.08),which was significantly lower than female (52.42 ± 11.97) (P ＜ 0.01).The onset age female and male proportion also had significant differences,age onset of male was in advance.The average body mass index was (24 ±3.47)kg/m2,most of the inpatients were workers and farmers,the level of education was primary and secondary.Multiple regression analysis hints,risk factor of onset age is the family history of diabetes,the history of hypertension,male,low academic qualifications.Percentage of newly diagnosed patients was 28.3％,about one-third in patients were with the metabolic syndrome,hyperlipidemia,high blood pressure,fatty liver.Conclusions Education level of the inpatients was lowe in the community,so strengthening diabetes education was required.The persons in the commuities who were male,or with the family history of diabetes,with high blood pressure history were of the communities require for early screening of diabetes mellitus,so the occurrence and development of diabetes woule be controlled.

Objective To investigate the clinical application and manifestation of dynamic contrastenhanced MRI (DCE-MRI) in differentiating true progession from pseudoprogression in patients with gliobastomas.Methods Twenty five glioma patients were treated with postoperative concurrent chemoradiotherapy and enrolled in this study.All patients were underwent DCE-MRI using a 1.5T scanner.Fifteen patients were confimmed by secondary pathology or clinical and imaging follow-up of patients with gliomas true progession (TP),10 patients were pseudoprogress (PP).Nonparametric Mann-Whitney test was used to compare perfusion parameters between two groups (TP and PP),were used for receiver operating characteristic (ROC) curve analysis to clear if these parameters can be the indicators to differentiate true progession from pseudoprogression.Results Ktrans (volume transfer constant),Ve (fractional volume of extravascular extracellular) values between TP and PP glioma groups were statistically significant,K and Ve values were significantly higher in the TP group than in the PP group (P ＜ 0.05).The areas under the ROC curve are 0.990 and 0.847,respectively.Kep (efflux rate constant) value,Vp (fractional volume of plasma) value in the identification of glioma TP group and PP group was not statistically significant (P ＞ 0.05).Conclusions DCE-MRI can be used to identify glioma TP and PP,Ktrans value and Ve value have clinical significance.

Objective To explore a new surgical method and its effect in repairing secondary nasal deformity of unilateral cleft lip.Methods Sixty-two patients with secondary unilateral lip and nasal deformity were treated with asymmetric butterfly incision combined with vestibular V-Y advance flap,and the subjective and objective indicators after operation were observed.Results All incisions healed with primary healing and all cases were followed up for 3-12 months.Fifty-eight cases got symmetric nostril and alar,the sum of absolute value of the nostril differences between both sides ＜ 3 mm.Two cases got symmetric nostril and alar,but the sum of absolute value of the nostril differences between both sides was 3.5 mm and 4.2 mm respectively.The alar relapsed again in 2 cases and the results were not satisfied,the sum of absolute value of the nostril differences between both sides ＞ 5 mm.Conclusions The method of using the asymmetric butterfly incision combined with vestibular V-Y mucosa flap can reset the skin,cartilages and mucosa to the anatomic position effectively.

OBJECTIVETo detect the mutation sites of exons 2, 20, 11A and 11B in Chinese patients with breast cancer.

METHODSA total of 86 patients with breast cancer without blood relationship were randomly selected. Polymerase chain reaction (PCR) and double-strand DNA direct sequencing were applied.

RESULTSNo mutations, especially deletions were found in exons 2, 20 and 11 with carefully checking the sequencing results, although they were reported frequently in Europe populations with breast cancer. We found one polymorphism in exon 11, with high frequency, and in the test of chi-square, the frequencies of two alleles had no significant difference between the patients and controls.

CONCLUSIONThe above results suggest this SNP may not be associated with the breast cancer in Chinese population, and indicates that the gene sequence of what we have studied doesn't account much for occurrence of the breast cancer in the population of China.

Objective:To investigate the quality issues of community home care service in Beijing.Methods:A study on quality of community home care service was conducted from March to May in 2021 in six urban districts of Beijing, and 10 community health service centers were selected as study sites by purpose sampling method. The quality issues of home care service were studied by observing the process of 17 home care services, interviewing medical staff and reviewing relevant medical documents.Results:The study extracted 3 structural quality problems and 6 process quality problems of home care service. The structural quality problems included unclear service scheduling and insufficient qualification of the personnel; lacking special transportations; and lacking home health service standards in some centers. The process quality problems included incomplete material preparation, wearing jewelry during medical procedures, no physical check-up before procedures, not strictly following the aseptic principle in the operation, not properly disposing medical wastes, wrong or missing filling of medical documents.Conclusions:There are some problems in the implementation of community home care service in Beijing, such as insufficient medical personnel and material resources, unclear service scheduling, lack of unified medical service standards, and insufficient quality management. Therefore, these problems should corrected to ensure the quality of community home care services in Beijing.

Patient medication safety is a global concern. Patient participation in the medication process can effectively reduce the occurrence of medication errors. Assessing the patient′s ability to participate in medication safety is conducive to identify problems in the participation process; therefore, to provide reference for corresponding intervention measures and further improve patient participation ability. This article introduces the currently used measurement tools of patient participation in medication safety, and provides reference for improving measurement index system in China.

Objective:To explore the effect of patient engagement on medication safety for patients with chronic disease through a systematic review.Methods:Relevant randomized controlled trials of patient engagement on medication safety were searched from PubMed, EMBASE, The Cochrane Library, CNKI, Wanfang and VIP database. The literature was screened according to inclusion and exclusion criteria, and data extraction and literature quality evaluation was conducted on the selected literature.Results:A total of 15 eligible studies was included. Most of the studies occurred in outpatient and home settings, and the subjects were patients with chronic diseases. Patient engagement strategies can be divided into three categories: (1) patient engagement in medical decision-making; (2) patient engagement in medication adjustment; (3) patient engagement in medication management. The outcomes of medication safety included medication adherence, medication knowledge, medication beliefs, adverse events and medication errors. Intervention strategies for patients to actively engage in medication safety significantly improved patients′ medication knowledge and beliefs, but did not improve medication adherence of patients.Conclusion:Promoting patient active engagement is an effective intervention measure to improve patients ′ perception of medication safety. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.

Objective:To discuss the method for establishing the rat models of irritable bowel syndrome(IBS)by chronic water avoidance stress(WAS)method,and to evaluate its feasibility.Methods:Thirty male Wistar rats were randomly divided into control group(n=10)and model group(n=20).The rats in model group were induced by WAS method for 1 h everyday,lasting for 10 consecutive days;the rats in control group underwent no interventions.After modeling,the general conditions and body weights of the rats in two groups were observed and recorded.The elevated plus maze(EPM)test was used to detect the percentages of the number of open arm entries(OE)and the time spent in open arms(OT)of the rats in two groups;the abdominal withdrawal reflex(AWR)test was used to assess the visceral sensitivity of the rats in two groups;electrocardiography was used to detect the heart rate variability(HRV)of the rats in two groups;electromyography(EMG)of the external oblique muscle was used to detect the colorectal pain sensitivity thresholds of the rats in two groups;multi-channel physiological signal recorder was used to monitor the slow wave frequency of the colon of the rats in two groups.Results:There were no death rats in both groups during the modeling period.After modeling,the rats in model group exhibited poor mental status,reduced spontaneous activity,hypoactivity,disordered and dull fur,irritability,and unclean anal areas;whereas,the rats in control group showed no significant changes in the mental state,spontaneous activity,fur,and perianal area.Compared with control group,the body weight of the rats in model group was significantly decreased(P<0.05).The EPM test results showed that compared with control group,the OE percentage and OT percentage of the rats in model group were significantly decreased(P<0.01).The AWR test results showed that 12 rats in model group scored≥3 points,indicating that the successful rate in creating the visceral pain models was 60%.Compared with control group,the low frequency(LF)signals and the ratio of LF/high frequency(HF)of the rats in model group were significantly increased(P<0.01),and the HF was significantly decreased(P<0.05).The EMG results showed that compared with control group,the coloretal pain sensitivity threshold of the colon of the rats in model group was significantly decreased(P<0.01),and the slow wave frequency of the colon was significantly increased(P<0.01).Conclusion:The WAS method for establishing the rat model of IBS effectively demonstrates the changes in behavior and mental state,increased the visceral sensitivity,accelerated colonic slow wave frequency,and autonomic nervous system imbalance;the WAS method can serve as an effective modeling approach for observing and evaluating the related drugs and interventions on treatment of IBS.
