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 investigate the early influences of laser photocoagulation on retinal function in diabetic retinopathy(DR). Methods The multifocal electroretinograms (MERG) of 30 eyes with DR (phase Ⅲ～Ⅳ) were tested with visual evoked response image system IV before,and the 3 rd day and the 7 th day after laser photocoagulation. Results Three days after photocoagulation, the latency of N1 prolonged in the central macula 5? area and superionasal quadrant.The response densities of N1,P1 and N2 markedly reduced, and most significant changes occurred in the central macula 5? area and then in the central 10?area. There were also differences in the changes of the amplitude of N1 and P1 in different quadrants .The changes of visual acuity were positively related to the decrease of amplitudes of N1,P1 and N2 in the macula. Conclusion The reduction of response densities in MERG reveals functional damage in diabetic retina occurring early after photocoagulation.The functional damage in macula induced indirectly by photocoagulation may explain the reduction of visual acuity after panretinal photocoagulation in some degree.

Objective To investigate the early effects of intervention with tanakan on retinal function in diabetic retinopathy(DR) after laser photocoagulation. Methods Prospective random controlled study was performed on 60 Patients (60 eyes) from 23 to 69 years old with DR(phase Ⅲ～Ⅳ). The multifocal electroretinograms (MERG) were tested with VERIS Ⅳ before , the 3rd day and the 7th day after photocoagulation. Results No significant differences were found in the latencies and response densities of N1,P1 and N2 between the two groups before photocoagulation. Compared with that before photocoagulation, three days after photocoagulation the latencies in tanakan group had no significant change. The response densities of N1,P1 and N2 reduced and the changes were much smaller than that in control. Three days after photocoagulation ,the response densities of P1 and N2 in the central macula 5? area were much higher and the latencies of P1 and N2 were significantly shorter than that in control group. There were no significant differences in the response densities in the 7th day and the differences in the latencies between two groups still existed. Conclusion Tanakan may be effective in preventing the retina from damage of retinal photocoagulation in some degree in DR.

Objective To investigate the methylation status of the promoter of RASSF2A gene in the tissues of cervical cancer and its impacts in tumorigenesis.Methods Methylation-specific PCR (MSP) and RT-PCR techniques were applied to detect methylation status of RASSF2A gene promoter region and RASSF2A expression in tissues of 62 cervical cancer and 30 normal cervical specimens,respectively.Results Methylation frequency of RASSF2A gene in cancer tissue was higher than that in normal tissue (53.2 ％ vs 13.3 ％,P ＜ 0.05).The mRNA expression of RASSF2A in cancer tissue were less than those in normal tissue significantly (0.254 3 ±0.102 7 vs 0.623 4 ± 0.063 8,t =0.932,P ＜ 0.05).The mRNA expressed of RASSF2A gene was lower in methylated promoter group than that in unmethylated promoter group in cancer tissue samples significantly (0.118 2 ± 0.035 2 vs 0.301 2 ± 0.076 4,t =0.481,P ＜ 0.05).Conclusion Hypermethylation of RASSF2A gene in promoter region,which lead to the loss of RASSF2A gene expression,might play an important role in tumorigenesis of cervical cancer.

OBJECTIVETo compare the efficacy differences in the treatment of somatoform pain disorder between resuscitation and tranquilization acupuncture technique and oral administration of deanxit.

METHODSForty cases of somatoform pain disorder (complicated with mild and moderate depression) were randomized into an acupuncture group and a western medication group, 20 cases in each one. In the acupuncture group. acupuncture was applied to Shenting (GV 24). Shuigou (V 26). Sishencong (EX HN I) to Baihui ((V 20) (penetrating technique). Feng-chi (GB 20). etc. The treatment was given once every day. 6 times a week. In the western medication group. the anti depression drug. deanxit was prescribed for oral administration, 1 tablet in every morning and lunchtime each day. In 8 weeks of continuous treatment, the visual analogue scale (VAS) and Hamilton depression scale 17 items (HAMD) were used to evaluate the efficacy in the patients of the two groups, the adverse reactions were observed and the recurrence rate was followed up in 3 months.

RESULTSAfter treatment. VAS and HIIAMD scores were all apparently reduced as compared with those before treatment in the patients of the two groups (all P<0.05). The reducing amplitude of VAS score in the acupuncture group was greater than that in the western medication group (P<0.05) and that of HAM) score was not different significantly as compared with that in the western mnedica tion group (P > 0.05). There was no adverse reaction in the acupuncture group and were 3 cases as dizziness, trembling. dry mouth and constipation in the western medication group. The curative and remarkably effective rate was 50.0 (10(20)) in the acupuncture group, better than 15.0% (3/20) in the western medication group (P<0.05). The recurrence rate was 10.0 (2/20) in the acupuncture group. lower than 35.0% (7/20) in the western medication group (P<0.05).

CONCLUSIONThe resuscitation and tranquilization acupuncture technique achieves the definite efficacy on somatoform pain disorder, relieves depression symptoms of patients, especially pain and reduces adverse reactions and recurrence rate. The effects of this therapy are advanced as compared with deanxit.

Objective To detect the relationship between CAG repeat in IT15 gene and clinical manifestations of Huntington's disease (HD).Methods Non-denaturing polyacrylamide gel electro- phoresis method was used to detect CAG repeat.Clinical manifestations were scored by UHDRS and MMSE. Results Genotypes of IT15 were heterozygous in all 29 HD patients.CAG repeat in the HD chromosome, being 42—62,13—28 in normal chromosome,was inversely correlated with age of onset (r=-0.539,P

OBJECTIVE: To compare the effects of bupivacaine, lidocaine and saline injections in alleviating post tonsillectomy pain. METHOD: We recruited 60 patients into the study. All subjects were randomly allocated into 3 groups. Group 1 received 0.9% sodium chloride (saline group), group 2 received 0.25% bupivacaine (bupivacaine group) and group 3 received 2% lidocaine (lidocaine group), infiltrated around each tonsil. Pain was evaluated with McGrath's face scale. RESULT: The postoperative pain scores at 2 and 6 hours were similar among the groups (P>0.05). The pain scores in the bupivacaine group were lower than those in the saline group at 12 h (P<0.05). The pain scores in the bupivacaine and lidocaine groups were significantly lower than those in the saline group from 18 to 24 hours until day 7 (P<0.05). There was no difference between the bupivacaine and lidocaine groups (P> 0.05). CONCLUSION Local infiltration of bupivacaine is a relatively and safe effective method and is equivalent to use of lidocaine for post tonsillectomy pain.
