OBJECTIVE:To understand the availability and affordability of essential medicines in Nanjing after implementing national essential medicine system,and to provide evidence for formulating and completing related policy. METHODS:With inves-tigation subjects of 6 classes of diseases with high incidence,WHO/HAI standard survey method was adopted to select 24 essential medicines and investigate and evaluate the availability and affordability of them in governmental health institutions and social retail pharmacies in Nanjing. RESULTS:Availability of essential medicines in community health service centers in Nanjing was lower than governmental hospitals and social retail pharmacies,and availability of lowest price generic drugs (LPGs) was much higher than original brand drugs (OBs);affordability was totally good,however,there were large gap in the affordability between OBs and LPGs,the affordability of OBs was relatively poor. CONCLUSIONS:The national essential medicine system has made some progress in Nanjing,but worse than expected. It is suggested to update and adjust the essential medicine list based on the clinical medication requirement,guarantee the equipment of essential medicines in medical and health institutions,popularize the knowl-edge about essential medicines,properly adjust the price of original brand drugs and ease the treatment burden.

Objective To explore the expression of mismatch repair gene (MMR) (MLH1,MSH2,PMS2 and MSH6) in endometrioid adenocarcinoma,and to analyze its clinical pathological significance.Methods Inmunohistochemical EnVision method was used to detect the expressions of DNA mismatch repair proteins (MLH1,MSH2,PMS2 and MSH6) in 101 cases of endometrial adenocarcinoma.The phenotypes of tumor microsatellite instability (MSI) and microsatellite stable were determined,and its relationship with onset age,differentiation,depth of myometrial invasion,lymphatic metastasis and prognosis of tumor were analyzed.Results There were 67 cases of hysterectomy and 34 cases of endometrial biopsy in 101 cases of endometrial adenocarcinoma.52 cases of surgical specimens and 14 cases of biopsy specimens were included in 66 cases that had complete follow-up data.Rates of negative expression were as follows:MLH1 31.6 ％ (32/101),MSH228.7 ％ (29/101),PMS2 16.8 ％ (17/101),MSH6 8.9 ％ (9/101).MSI phenotype 53.5 ％ (54/101),MSS phenotype 46.5 ％ (47/101).Univariate analysis showed that prognoses of MSI-L&MSS group (34 cases) were better than those of MSI-H group (18 cases) in hysterectomy organization (P =0.041).The differences between depth of myometrial invasion,degree of differentiation,age and prognosis of endometrial adenocarcinoma were statistically significant (P ＜0.05).Cox multivariate analysis showed that differences between depth of myometrial invasion,age and prognosis of endometrial adenocarcinoma were statistically significant (P =0.034,P =0.009),while there was no significant difference between MSI-L&MSS group and MSI-H group in prognosis (P ＞ 0.05).Conclusions MSI is one of the molecular events that occur in the endometrioid adenocarcinoma.Age and depth of tumor invasion are independent prognostic factors of endometrioid adenocarcinoma.In view of inconsistency between univariate analysis and multivariate analysis,whether MSI can be used as deterministic accordance for endometrioid adenocarcinoma prognostic evaluation requires further verification.
