OBJECTIVE:To control the drug quality risk in drug withdrawal links of hospital pharmacy,and provide reference for the application of quality risk management(QRM)in hospital pharmacy. METHODS:Drug QRM was developed in drug with-drawal links through risk identification,risk assessment,risk control,risk assessment and other steps. Using the incidence of risk factors and reusable rate of withdrawal drug as indexes,related data of before(Jul.-Dec. 2015)and after(Jan.-Jun. 2016)devel-oping QRM in our hospital were compared to evaluate the effect of drug QRM. RESULTS:Determining whether specific storage drugs kept the required storage conditions,whether the numbers of withdrawal drugs counted to minimal packaging and other 5 fac-tors were high-risk factors(the risk score of each factor>4 points);control measures were taken separately for high risk factors, then high-risk factors were reduced to acceptable levels(risk score<4 points). After developing QRM,the incidence of risk factors were reduced than before(reduce 1.35%-6.19%),reusable rate of withdrawal drug was increased(98.64% vs. 86.32%)(all P<0.05). CONCLUSIONS:Developing QRM in drug withdrawal links of hospital pharmacy can reduce the drug quality risk.

AIM: To determine the aqueous, vitreous, serum levels of pigment epithelium-derived factor (PEDF)and vascular endothelial growth factor(VEGF)in patients with proliferative diabetic retinopathy(PDR), and to speculate on the source of the change in concentration and to discuss its clinical significance.METHODS:Forty-one eyes withproliferative diabetic retinopathy were included in the study, 16 of which were complicated by neovascularization of iris (NVI).Twenty-one eyes with idiopathic macular hole (MH)were as controls. The aqueous, vitreous, serum levels of PEDF and VEGF of all the groups were determined with ELISA. PEDF, VEGF and the levels in the three groups were compared with analysis of variance (ANOVA). The PEDF, VEGF concentrations in aqueous,vitreous and serum were analyzed with Pearson correlation test,and the correlation of PEDF and VEGF levels was also analyzed with Pearson correlation test.RESULTS:The aqueous levels of PEDF decreased significantly in sequence in groups of control, PDR without NVI, PDR with NVI. VEGF levels increased coordinately. The similar findings existed in vitreous samples. The PEDF,VEGF levels in aqueous were not correlated significantly with those in serum,but correlated positively with those in vitreous. The intraocular levels of PEDF had a negative correlation to those of VEGF.CONCLUSION:The reduction of intraocular PEDF level and elevation of intraocular VEGF level may play an important role in the occurrence and progression of PDR. In the development of PDR, the PEDF,VEGF levels in aqueous may be mainly effected by local pathological changes, as anti-angiogenic and pro-angiogenic factors, their unbalanced intraocular distribution may promote the angiogenesis of the iris and retina.

Objective To evaluate the clinical application value of amniotic membrane transplantation in the treatment of intrauterine adhesions.Methods Totally 48 intrauterine adhesions patients of infertility were treated with amniotic membrane transplantation from January to December 2013 in our hospital.They were divided into mild adhesion in 11 cases (group A),moderate adhesion in 17 cases (group B),and severe adhesive group in 20cases (group C) by American Fertility Association.They were treated with amniotic membrane transplantation and estrogen/progesterone sequential treatment after operation.Clinical effect and feasibility of each group were analyzed.Results There was statistical significance in the endometrium thickness after 3 months (P ＜ 0.05).The menstruation of all patients with mild and moderate intrauterine adhesion (IUA) was improved,and the menstrual improvement rate in patients with severe intrauterine adhesions was 90％.IUA cure rate of groups A,B,and C were different after 3 months of surgery,[groupA100％ (11/11),group B 94.1％ (16/17),group C70％ (14/20),x2 =6.73,P ＜0.01],The cure rate of group A was significantly higher than that of group C (x2 =4.00,P ＜ 0.05),although the cure rate of group B was higher than that of group A,but the difference was not statistically significant (P ＞ 0.05).Conclusions The cure rate of amniotic membrane transplantation combined with estrogen in the treatment of intrauterine adhesions was high.It could promote the recovery of the endometrium and improve the recovery of menstruation.There was no transplantation rejection and safety.It also had the advantages of easy drawing materials,simple operation,and can be applied to clinical application and promotion.

Objective:This study has two objectives. One is to detect the methylation status of reversion-inducing cysteine-rich protein with Kazal motifs (RECK, a new tumor suppressor gene) gene promoter in primary laryngeal squamous cell carcinoma and nor-mal laryngeal mucosa. The other is to analyze the correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma. Methods:Methylation-specific polymerase chain reaction was used to detect the RECK gene methylation of 70 specimens of laryngeal squamous cell carcinoma and 15 normal tissues of laryngeal mucosa. The patients underwent six cycles of ra-diotherapy and were followed-up for 5 years. The correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma was analyzed. Results: After six cycles of radiotherapy, 47 patients (67.14%) showed sensitivity and 23 (32.86%) showed tolerance to radiotherapy. The methylation level of the RECK gene was lower in the radiation-sensitive group than in the nonradiation-sensitive group (P<0.05). The methylation level of the RECK gene was lower in the remission group than in the non-remission group. RECK gene methylation could increase the risk of cancer by approximately 5.010 times (OR=5.010, 95%CI:1.616-15.533). Conclusion:RECK gene promoter methylation in human laryngeal squamous cell carcinoma is an early event that is correlated with the patient's sensitivity to radiotherapy. Thus, the patient's sensitivity to radiation can be predicted by detecting the meth-ylation status of the RECK gene promoter.

Based on the clinical application of ERA (easy resilient attachment), the construction of two kinds of ERA were introduced including outside-crown-EAR and root-EAR. The clinical operation and attention of EAR application were demonstrated by clinical cases.

Objective To investigate the mastery of clinical students' doctor-patient communi-cation skills and to assess the teaching effectiveness about the doctor-patient communication, and then propose some improvement ideas. Methods We conducted a study in students of clinical medicine of Nanjing Medical University in Grade 2009, using Objective Structured Clinical Examination (OSCE) after internship, which included graduation assessment of doctor-patient communication skills. Then we analyzed the doctor-patient communication skills and related scores of students trained in different clinical medical programs. Results The average score of doctor-patient communication skills of 549 students was (82.72±4.23), of which, the average score of 329 five-year students of clinical medicine was (81.88±4.23) and the average score of seven-year students was (83.96±3.91) in. The average score of seven-year students of clinical medicine was significantly higher than five-year students (P=0.000). Moreover, there was a significant positive correlation between the total score of OSCE and the score of doctor-patient communication skills in both five-year and seven-year students of clinical medicine (five year program students' score correlation coefficient was 0.520, P=0.000;seven year pro-gram students' score correlation coefficient 0.416, P=0.000). Conclusion The teaching effectiveness of doctor-patient communication has proved to be quite effective, and it is definitely of great significance in improving clinical students' doctor-patient communication skills. The score of the assessment of the doctor-patient communication reflects not only the training effectiveness of the communication skills, but also the comprehensive capacity.
