ABSTRACT

Ethnic medicine is an important part of traditional Chinese medicine, which has encountered many problems in the development process, such as the lack of effective inheritance of valuable experience and practice, weak basic research and lack of talents, serious destruction of ethnic medicine resources, uneven quality of medicinal materials, weak intellectual property protection, etc. To sum up, these seriously restrict the development of ethnic medicine. Here, the authors propose some corresponding suggestions according to these problems. Firstly, we should try our best to protect and mine relevant professional books for promoting national medicine culture, establish complete system of national and local standards, strengthen the construction of standardized planting bases and germplasm resource banks, build a well-known brand of ethnic medicine and give full play to the leading role of the brand. Secondly, we should strengthen basic research on ethnic medicine and build an integrated system of production-study-research. By integrating the strength of culture, scientific research, talents and industry, this paper hopes to promote the vigorous development of ethnic medicine.

ABSTRACT

A cognitive magnetic resonance imaging (MRI)-targeted prostate biopsy conducted by an experienced clinician enhances the detection rate of (high-grade) prostate cancer; however, this method is less successful in the hands of inexperienced surgeons. Therefore, an alternative method of conducting a cognitive MRI-targeted biopsy that can be successfully performed by the inexperienced clinicians should be developed. Ninety-six males suspected of prostate cancer were analyzed using systematic biopsy and cognitive MRI-targeted biopsy based on our novel three-dimensional matrix positioning method. Typically, the core principle of the latter procedure was to put the MRI and ultrasound images into the same virtual coordinate system. Afterward, the targeted biopsy was transformed to target a coordinate for the suspected lesion in the MRI. Subsequently, patients were assessed for the presence/absence of prostate cancer or high-grade prostate cancer. According to our results, the overall detection rate of prostate cancer was 70.8% (68/96), and the detection rate of high-grade prostate cancer was 56.3% (54/96). Specifically, the detection rate of prostate cancer by systematic biopsy was 54.2% (52/96) and that by targeted biopsy was 59.4% (57/96; P = 0.560). Clearly, the combined application of targeted biopsy could remarkably increase the detection rates of prostate cancer (P = 0.025) and high-grade prostate cancer (P = 0.009). Taken together, the findings of this study suggest that the combination of systematic biopsy with our three-dimensional matrix positioning-driven cognitive-targeted biopsy is superior to systematic biopsy in detecting prostate cancer and high-grade prostate cancer.

ABSTRACT

BACKGROUND@#The role of local treatment in oligometastatic prostate cancer (PCa) is gaining interest with the oligometastases hypothesis proposed and the improvement of various surgical methods and techniques. This study aimed to compare the short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy (RALP) for oligometastatic prostate cancer (OPC) vs. localized PCa using propensity score matching.@*METHODS@#Totally 508 consecutive patients underwent RALP as a first-line treatment. The patients were divided into two groups according to oligometastatic state: the OPC group (n = 41) or the localized PCa group (n = 467). Oligometastatic disease was defined as the presence of two or fewer suspicious lesions. The association between the oligometastatic state and therapeutic outcomes of RALP was evaluated, including biochemical recurrence (BCR) and overall survival (OS). A Cox proportional hazards model was used to assess the possible risk factors for BCR.@*RESULTS@#Totally 41 pairs of patients were matched. The median operative time, the median blood loss, the overall positive surgical margin rate, the median post-operative hospital stays, and the post-operative urinary continence recovery rate between the two groups showed no statistical significance. The 4-year BCR survival rates of the OPC group and localized PCa group were 56.7% and 60.8%, respectively, without a significant difference (P = 0.804). The 5-year OS rates were 96.3% and 100%, respectively (P = 0.326). Additionally, the results of Cox regression showed that oligometastatic state was not an independent risk factor for BCR (P = 0.682).@*CONCLUSIONS@#Our findings supported the safety and effectiveness of RALP in OPC. Additionally, oligometastatic state and sites did not have an adverse effect on BCR independently.

ABSTRACT

Objective To observe the curative effect,failure pattern and treatment-related toxicities of elective nodal irradiation (ENI) and involved field irradiation (IFI) in patients with thoracic esophageal squamous cell carcinoma treated with radical radiotherapy, and determine the reasonable target delineation of radiotherapy. Methods Using prospective randomized controlled design, a total of 86 patients with thoracic esophageal squamous cell carcinoma were randomly allocated to two groups:ENI group(n=39)and IFI group(n=47).Both groups received concurrent chemoradiotherapy.In ENI group,the high-risk lymphatic drainage area received prophylactic irradiation on the basis of IFI group.After the treatment, all patients were followed up for 3~33 months.The median follow-up period was 15 months.The short-term effective rate, one year survival rate, progression free survival rate and the local control rate of two groups were calculated. The survival curve was drawn by the Kaplan-Meier method,and the survival rate was compared using the Log-rank method.Meanwhile, the treatment failure pattern and incidence of adverse reactions were analyzed in the two groups. Results There was no significant difference in effective rate between ENI group and IFI group (92.3% vs. 95.7%,χ 2=0.460, P>0.05). The one-year survival rates were 66.7% and 68.1% for the two groups,respectively.The progression-free survival rates were 56.4% and 53.2% respectively.The local control rates were 92.3% and 87.5% respectively,with no statistical difference(P>0.05). The median survival time was 15 months at the end of the follow-up for group ENI and group IFI, and there was no significant difference in survival rate between two groups(Log-rank χ2=1.520,P=0.218).There were 35 cases with treatment failure in all 86 patients, of which 17 cases were in group ENI and 18 cases in group IFI. The regional failure rates were 35.9% and 27.7% in ENI and IFI groups respectively,distant metastasis rates were 20.5% and 14.9% respectively,in-field failure rates were 30.8% and 23.4% respectively, and out-of-field failure rates were 4.3% and 5.1% respectively, which showed no significant differences (P>0.05). There were no significant differences in side effects, the incidence of bone marrow suppression,gastrointestinal reactions,radiation esophagitis and radiation-induced lung injury between two groups (P>0.05). Conclusion ENI shows similar recent efficacy, failure patterns, adverse reactions and prognosis with IFI for thoracic esophageal squamous cell carcinoma patients receiving radical radiotherapy. So IFI treatment is recommended to minimize the exposure dosage of normal tissue.

ABSTRACT

Objective To research the monoclonal antibody KMP1 inhibited bladder cancer EJ cell lines growth and metastasis in vivo by bioluminescence imaging. Methods Immunohistochemistry was used to determine the KMP1 binding to EJ and EJ-GFP cell lines. The xenograft tumor cell growth and distribution were measured by vernier calipers and dynamic in vivo fluorescence imaging. Immunohistochemistry and H&E counterstaining researched the feature of the xenograft tumor. Results Cell growth curves of EJ and EJ-GFP cells were similar. EJ-GFP had a green fluorescence. In EJ-GFP nude mouse tumor model, the addition of KMP1 significantly inhibited tumor growth and extended the average life span of nude mice. Both EJ and EJ-GFP cells can bind to KMP1,and the weight of transplanted tumors in the KMP1 treatment group was significantly lower than that of the mIgG control group (P<0.001).Conclusion KMP1 has a promising antitumor effect in vivo. It might be valuable for development as a promising targeted agent for bladder cancer.

ABSTRACT

Objective To validate the value of MRI and ultrasound three-dimensional matrix positioning technique in transperineal targeted prostate biopsy so as to improve the positive rate of prostate biopsy. Methods A total of 15 patients received transperineal targeted prostate biopsy using MRI and ultrasound three-dimensional matrix positioning technique + traditional systemic prostate biopsy from Feb. 2015 to Jun. 2015 in Changhai Hospital, Second Military Medical University. The 15 patients met the following criteria:(1) at least one negative prostate biopsy; (2) had the indications for performing re-biopsy; and (3) MRI showed suspected sites of prostate cancer (the PI-RADS scores were 4-5). Before biopsy, all the MRI images were reconstructed and the three-dimensional coordinates(X, Y, Z axis) were confirmed. After general anesthesia, systemic prostate biopsy was performed under the guidance of transrectal ultrasound. Then the transrectal ultrasound-guided biopsy was carried out according to the location in previous MRI images, which were located by the three-dimensional coordinates (X, Y, Z axis). Results Fourteen (93. 3%) of the 15 patients were finally confirmed with prostate cancer, with 13 (86. 7%) being positive only in targeted biopsy, and 6 (40. 0%) being positive only in systemic biopsy. There was only 1 (6. 7%) whose targeted biopsy result was negative and systemic biopsy result was positive, and there were 8 cases (53. 3%) with positive targeted biopsy but negative systemic biopsy. Only 1 case (6. 7%) was negative in both targeted biopsy and systemic prostate biopsy. There was significant difference in positive rates between the targeted biopsy and systemic biopsy (P=0. 002). Conclusion Transperineal targeted prostate biopsy with MRI and ultrasound three-dimensional matrix positioning technique can accurately locate and target puncture the suspected site of prostate cancer in MRI images, and it has a higher diagnostic efficiency especially for the sites which are relatively easy to be missed by systemic prostate biopsy, but its performance still needs further large sample studies.

ABSTRACT

Objective To explore the teaching method for transrectal ultrasound guided prostate biopsy, so as to shorten the learning curve and reduce the complications during the study period. Methods Six residents of urology, who had 2-3 years experience of urology and had no experience in transrectal ultrasound biopsy, were randomly divided into two groups: experimental group and control group (n = 3). All the members were trained to perform transrectal ultrasound-guided 12 needle biopsy of the prostate. The experimental group received the modularized step-by-step training mode; and the control group received the traditional method, which included operation teaching and independent operation of the whole process. Fourteen days later, all the members were tested for manipulation and surveyed by questionnaires on the training. Results All the 3 residents in the experimental group were capable to perform the operation successfully after 14 days, while only 1 resident in the control group can do t smoothly. The questionnaire survey showed that, all the 3 residents in the experimental group thought that the training procedure was easy and interesting, and they were not nervous during the operation. In the control group, only 1 resident felt t was easy, and the other 2 felt t was difficult and boring, and they were liable to be nervous and forgetful in clinical practice. Conclusion The modularized step-by-step training mode can greatly improve the learning efficiency of training for transrectal ultrasound guided prostate biopsy, making the learning process simple and interesting.

ABSTRACT

<p><b>BACKGROUND</b>Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. Pulmonary rehabilitation (PR) is an established intervention for the management of patients with COPD. Exercise training is an important part of PR, and its effectiveness in patients with COPD is well established. However, alternative methods of PR training such as Daoyin have not been appropriately studied. Hence, alternative forms of exercise training that require less exercise equipment and no specific training place should be evaluated. This paper describes the study protocol of a clinical trial that aims to determine if pulmonary Daoyin training will improve the exercise capacity and psychosocial function of patients with COPD in China.</p><p><b>METHODS AND DESIGN</b>A multicenter, randomized, controlled trial will be conducted. A total of 464 patients meeting the inclusion criteria will be enrolled into this study with 232 patients in each of the trial group and the control group. Based on patient education, patients in the trial group will receive pulmonary Daoyin and continue with their usual therapy for three months. In the control group, patients will continue with their usual therapy. The primary outcome measures are exercise capacity assessed by the six-minute walking distance test and lung function. Secondary outcomes include dyspnea and quality of life. Measurements will be taken at baseline (month 0) and after the study period (month 3).</p><p><b>DISCUSSION</b>It is hypothesized that pulmonary Daoyin will have beneficial effects in improving exercise capacity and psychosocial function of patients with stable COPD, and will provide an alternative form of exercise training that is accessible for the large number of people with COPD.</p><p><b>TRIAL REGISTRATION</b>This trial has been registered in ClinicalTrials.gov. The identifier is NCT01482000.</p>

ABSTRACT

Background and Objectives: Stroke is the most common neurological disease in China and regulation of lipid levels is important for secondary prevention. This study aimed to investigate the practice of lipid lowering agents immediately after and one month following ischemic stroke in China, and to determine the factors affecting the practice. Methods: A total of 857 patients with acute ischemic stroke were enrolled from 11 hospitals in the Qingdao area, Northern China. Data pertaining to the patients’ demographic, clinical data, and treatment before and after the stroke were recorded. Univariate and multivariate logistic regression analyses were used to determine the factors associated with the treatment at two time points: at the acute stage and at one month follow-up. Results: The frequency of lipid lowering therapy was 50.3% (431/857) at acute stage and 41.5% (306/738) at one month. Lipid lowering therapy at acute stage was independently and positively associated with a history of hyperlipidemia((P=0.002, OR (95%CI): 3.784 (1.610-8.898)) and excess alcohol consumption (P=0.005, OR (95%CI): 1.928 (1.214-3.062)), partial anterior circulation infarct classifi cation (P=0.000, OR (95%CI): 1.974 (1.370-2.767)), and low-density lipoprotein levels ((P=0.000, OR (95%CI): 1.426 (1.170-1.739)). Lipid lowering therapy at one month follow-up was independently and positively associated with lipid lowering therapy at acute stage ((P=0.000, OR (95%CI): 18.275 (11.476- 29.101)), and negatively with the Modifi ed Rankin Scale ≥4 at follow-up ((P=0.030, OR (95%CI): 0.568 (0.341-0.948)). Conclusions: Lipid lowering therapy was found to be used in about half of patients during acute and early secondary prevention of ischemic stroke in the Qingdao area of Northern China. There should be more education efforts to the health care professionals and public to increase its use.

ABSTRACT

Objective To describe the prevalence and risk factors of hepatitis C virus (HCV) occurred in Henan province,at the end of 2011.Methods Five villages round Maqiao township,including 5187 residents,were selected for the study.Five-milliliter-blood was drawn from every one of the interviewee.Clinical data including age,gender and anti-HCV antibody was recorded.Patients with positive antibodies against HCV were tested for HCV RNA.Results A total number of 5187 people from five villages were studied,with age span from 1 to 97.The average age was 48 years and the sex ratio was 1 ∶ 1.34.The anti-HCV result showed that the prevalence was 2.27%,with 1-9 age group the lowest ( 1.55% ) and the ≥50 year-olds the highest (4.93%).Different villages seemed to have significant differences on the prevalence of HCV,with the highest as 8.68% and the lowest as 0.55%.Under risk factors analysis and distance-infection rates linear regression analysis,data showed that the prevalence might have correlated to the behavior of a certain family-run clinic.Results from multivariate analysis indicated that factors as intravenous dropping,intravenous injection and the use of surgery/endoscope were associated with the HCV infection in this village.Conclusion Although the public health care system had been developed for more than ten years,iatrogenic infection was yet responsible for the infection of HCV patients in the rural areas of China that called for further attention paid to the system.
