To study the influence of individualized medication guidance based on an Short Messaging Service( SMS) platform on the medication compliance in the patients with diabetes. Methods: Totally 100 cases of diabetic patients from the outpa-tient section were randomly divided into two groups using a number method with 50 ones in each, namely odd number was in the obser-vation group and even number was in the control group. The observation group was given pharmaceutical guidance based on the SMS technology platform by pharmacists, and the control group was given telephone follow-up once a week to understand the medical situa-tion. At the beginning of the study and after three-month treatment, the medication compliance in the two groups was evaluated, and the control situation of blood glucose was also compared. Results:There was no significant difference in the medication compliance be-tween the two groups at the beginning (P>0. 05). After the 3-month treatment, the blood glucose and medication compliance between the two group had statistical significance (P<0. 01). Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.

BACKGROUND:Pneumonectomy, extracorporeal circulation, lung transplantation and pulmonary embolism can cause ischemia/reperfusion injury of lung tissue. Lung ischemia/reperfusion injury is an important factor of lung function disorders after lung transplantation. OBJECTIVE:To analyze the effect of ischemic postconditioning on rat models of lung ischemia/reperfusion injury. METHODS:Twenty-four male SD rats were randomly divided into sham, ischemia/reperfusion and ischemic postconditioning groups (n = 8 rats/group) to establish the lung ischemia/reperfusion injury model. The rats in the sham group were only subjected to separation of the hilum of left lung and pulmonary arteries and veins, without blocking. The rats in the ischemia/reperfusion group were subjected to another 2 hours of reperfusion after 1 hour of lung ischemia. The rats in the ischemic postconditioning group were first subjected to 30 seconds of lung ischemia and 30 seconds of reperfusion for three times, and then to 2 hours of reperfusion. After the experiment, the specimens of lung tissue were obtained to detect the wet/dry weight ratio of lung tissue, activities of superoxide dismutase, malondialdehyde and myeloperoxidase, the contentsof inflammatory cytokines tumor necrosis factor α, interleukin-1β and interleukin-6, and the histopathological changes of lung tissue were observed. RESULTS AND CONCLUSION:Compared with the sham group, the wet/dry weight ratio of lung tissue, activities of myeloperoxidase and myeloperoxidase, the levels of tumor necrosis factor α, interleukin-1β and interleukin-6 were significantly increased (P < 0.05) in the ischemia/reperfusion and ischemic postconditioning groups, however, the increase levels of these indices were not significant in the ischemic postconditioning group, and the contents and activities in the ischemic postconditioning group were al significantly decreased (P < 0.05) compared with those in the ischemia/reperfusion group. In the ischemia/reperfusion and ischemic postconditioning groups, the activity of superoxide dismutase was obviously lower than that in the sham group, however, the activity of superoxide dismutase in the ischemic postconditioning group was obviously higher than that in the ischemia/reperfusion group. Pathological examination showed that thickened alveolar wal, edema and a large amont of inflammatory cel infiltrations were observed in the lung tissue of rats in the ischemia/reperfusion group. The degrees of alveolar wal thickening and edema in the lung tissue of rats in the ischemic postconditioning group were mild compared with the ischemia/reperfusion group, and in addition, some inflammatory cels were infiltrated. The histopathological scores of lung tissue in the ischemic postconditioning group were lower than those in the ischemia/reperfusion group. These results suggest that ischemic postconditioning plays its protective role on rat models of ischemia/reperfusion injury by inhibiting inflammatory cel accumulation, oxygen free radical production and pro-inflammatory cytokine release after ischemia/reperfusion injury.

Objective To investigate the compliance with medical therapy in elderly patients with benign prostatic hyperplasia (BPH).Methods The BPH patients aged 66 to 93 treated with 5α-reductase inhibitor (finasteride) and/or α-blockers (tamsulosin,doxazosin or terazosin) were followed up for 6 months.The retrospective data,including international prostatic symptom score (IPSS),quality of life (QOL),maximum flow rate (Qmax),prostate volume (PV),the information of medical types,total number of days of medication supplied,discontinuation and switching of therapy,and adverse effects were collected and analyzed.Results In all 103 subjects,30 patients (29.1％) received α-blockers,25 patients (24.3％) received finasteride,and 48 patients (46.6％)received combination therapy.After a follow-up of 6 months,the medication possession ratio (MPR)was 0.89±0.23 with a good-compliance rate (MPR≥0.8),discontinuation rate and switching rate were 79.6％ (82 cases),5.8％ (6 cases) and 6.8％ (7 cases),respectively,while the efficacy rate,the adverse reaction rate,incidence of acute urinary retention (AUR) and incidence of BPH related operations were 73.8％ (76 cases),12.6％ (13 cases),15.5％ (16 cases) and 4.9％ (5 cases),separately.The MPR (0.90±0.24) and good-compliance rate (84.0％) in patients treated with finasteride were both greater than those with α-blockers (0.87 ± 0.25,76.7％) and combination therapy (0.89 ±0.22,79.2％),but with no significant difference.Compared with patients with badcompliance,the efficacy ratio of medical therapy was significant higher in patients with goodcompliance (81.7％ vs.42.9％),while the incidence of adverse effects and AUR were significant fewer (7.3％ vs.33.3％ and 9.8％ vs.38.1％).Conclusions Elderly patients received either monotherapy or combination therapy with finasteride and α-blockers have good-compliance,which might be associated with the good effect of medical therapy and fewer adverse effects.

BACKGROUND: Neuroglioma is easy to recur, the focus of infection in which is rich in new vessels. Different expression of vascular endothelial growth factor (VEGF) may be related with the pathologic changes and recurrence of tumor.OBJECTIVE: To analyze the characteristics of VEGF expression in recurrent brain glioma.DESIGN: Control test.SETTLNG: Department of Neurosurgery, West China Hospital of Sichuan University.PARTICIPANTS: Forty-four (22 pairs) samples of neurogliocytoma before and after the recurrence with complete clinical data were collected from143 paraffin embedded samples, which were obtained from the operation between June 1996 and June 2001 in West China Hospital and pathologically proved to be brain gliomas. Samples were collected separately from the first operation and first recurrence, in which 8 cases belonged to grade Ⅰ of Kernohan scale, 10 were grade Ⅱ , 14 were grade Ⅲ and 12 were grade Ⅳ. The enrolled samples were divided into two groups: primary group and recurrent group with 22 cases in each group.METHODS: The immunohistochemiscal method was adopted. First antibody was goat-anti-human VEGF (mono-antibody), and second antibody was rabbit-anti-goat with the working concentration of 1:50. The phosphate buffered solution (PBS) was taken as negative control for staining instead of first antibody. The protein expression of VEGF in brain gliomas of 44 cases before and after the recurrence were detected and the cross-check analysis was conducted by combing with pathologic grades. ① The buff grains in intracytoplasm were positive signals. ②MPLAS-500 media mix chromatic pathologic imaging and literal analytical system were used to detect the PU (positive unit) value and number of tumor cells.③95% were the critical value of PU value, and the positive cell rates were calculated respectively. ④Routine hematoxylin-eosin stain was used for pathologic grades (Kernohan). MAIN OUTCOME MEASURES: ① PU value and the intensity of VEGF expression in brain glioma samples before and after the recurrence. ②The pathologic grades of brain gliomas before and after the recurrence. RESULTS: ①The expression of VEGF in primary and recurrent groups of brain glioma: the primary group was 21.927 3±6.607 and the recurrent group was 33.054 5±6.684. ② Pathologic grades: In 8 cases of primary grade Ⅰ gliomas, there were 2 cases of grade Ⅱ in recurrence, 5 cases of grade Ⅲ in recurrence, 1 case of grade Ⅳ in recurrence. In 6 cases of primary grade Ⅱ gliomas, there were 2 cases of grade Ⅱ in recurrence, 1case of grade Ⅲ in recurrence, 3 cases of grade Ⅳ in recurrence. In 6eases of primary grade Ⅲ .gliomas, 2 cases of grade Ⅲ in recurrence, 4cases of grade Ⅳ in recurrence. In 2 cases of primary grade Ⅳ gliomas,there were 2 cases of grade Ⅳ in recurrence. ③ Differences in PU value of VEGF protein expressions and pathologic grades of brain glioma samples before and after recurrence in self-compared detection were remarkable (P＜0.05).CONCLUSION: The expression of VEGF in recurrent glioma is higher than primary glioma, and there is a worsening tendency in recurrent tumor and the high-expression of VEGF in glioma plays an important role in the recurrence.

Safety hospital centralized monitoring is one of the important methods for evaluating the medication safety of TCM injections in clinic.It is critical to warrant research quality by reasonable statistical analysis.However,universally accepted standards and guidelines for the statistical analysis of hospital centralized monitoring of TCM injections have not been issued so far,which would probably reduce the research quality of safety hospital centralized monitoring of TCM injections since the unreasonable use of statistical analysis methods.Combined with previous practical experience and understanding,we put forward the problems of statistical analysis of hospital centralized monitoring of TCM injections with the provision of some advice in this paper based on the analysis of the preceding studies,laying a foundation for the same kind of researches.

The launch of the clinical trial registry is a milestone event in the field of clinical research in the 21st century that has played an important role in safeguarding the openness,transparency,ethics,data sharing and process control of clinical research.The current clinical research registry is mainly aimed at clinical trial research with lack of professional registration system for security and other real events of observational study.In order to improve the level of clinical safety research,promote transparency and process quality control,we proactively proposed and established a registration platform for clinical safety research of traditional Chinese medicine.This paper made a brief introduction hereof.

According to the related requirements of safety reevaluation of TCM injections,hospital centralized monitoring of the safety of TCM injection was consecutively pressed ahead.Centralized security monitoring was a large-scale real world research involving numerous data acquisition,transmission,verification and analysis.The quality of data acquisition and data verification directly affected the authenticity and reliability of research data and results.Therefore,data management played a significant role in the safety monitoring of TCM injections.Based on the analysis of previous researches,this paper discussed the implementation content,links and the frequent problems and corresponding solutions of data management during the safety monitoring of TCM injections,combining with the experience in the implementation of projects.

The implementation process management plays a important role for the quality of centralized safety monitoring study of post-marketing Chinese medical injections.One of the critical link is hospital.Currently,there is no principle or specification for hospital choosing,number of monitoring points,data collection responsible part and forms of data collection as well.These issues caused uneven quality,huge differences in results and questioned conclusion.Based on the previous research experience,this paper focused on discussing the link of hospital where research data may be influenced,and proposed some suggestions.

The safety of TCM injection triggered attentions and hotspots in recent years in China.The centralized monitoring of TCM injection provided important evidence for analyzing the safety risk of TCM injections,recognizing adverse reactions and contraindications and perfecting the instructions.This study aimed at exploring the ethical problems on centralized monitoring.In this paper,we retrieved and screened the ethical issues of TCM injections over hospital centralized monitoring in China National Knowledge Infrastructure (CNKI,1979-Ju1.,2016).Issues over it were put forward and addressed.It is found that the current ethical issues related to hospital centralized monitoring lacks sufficient attentions,corresponding norms and requirements.Based on the ethical issues reflected from the literatures,suggestions should be pressed ahead with the ethical review of centralized surveillance,signing of informed consents,registration of research programs,data statistics and reporting stages,for the better protection of the rights and interests of subjects and improvement of research quality.
