OBJECTIVE:To provide reference for further improving negotiation mechanism of drug medical insurance in Chi-na. METHODS:Questionnaire investigation was conducted among the medical insurance agency and pharmaceutical company staff who participated in drug medical insurance negotiation in Jiangsu province,Jiangxi province,Qingdao,Chengdu. Their business fa-miliarity and recognition of the negotiating mechanism were also investigated. The descriptive analysis,independent sample t test and other methods were adopted to analyze the data statistically. RESULTS:A total of 70 questionnaires were distributed and 68 val-id questionnaires were collected with effective recovery rate of 97.14%. Respondents included 21 staff members of medical insur-ance agencies and 47 of pharmaceutical companies. In terms of business familiarity,the average score of respondents in all aspects was greater than 3(4 points system),the lowest score wasmanagement of the implementation of drug negotiation projects. There were statistical significances in scores of 3 items between 2 parties in the negotiation(P<0.05):basic principles of the drug negotiation process should be followednegotiation objectives in the substantive negotiation process total score of busi-ness familiarity. The scores of respondents in pharmaceutical companies were higher than those of health insurance agencies. In the recognition of the negotiating mechanism,average score of each survey item was ≥4(5 points system)in the recognition of the overall effect of the negotiation mechanism except forwhich is conducive to maintaining the price system of pharmaceutical com-panies. The average score of all aspects of preparation of the negotiations,substantive negotiation,implementation of the negotia-tion agreement and negotiation project's supervision and evaluation was >4 except forpatients taking drugs is quick and easy. There was no statistical significance between 2 types of respondents in all aspects of overall effect of the negotiation mechanism, preparation of the negotiations and negotiation project's supervision and evaluation(P>0.05). But in the recognition of the substan-tive negotiation,there was statistically significance between 2 types of respondents innegotiations between the two sides in an equal,cooperative,harmonious atmosphere(P<0.05). Healthcare agencies'respondents had higher scores than pharmaceutical companies'ones. And in the recognition of the implementation of the negotiation agreement,there was statistical significance be-tween 2 types of respondents in theafter the agreement entered into force,the medical insurance agency will be strictly in accor-dance with the agreementandfund pay to pharmaceutical companies timely and reasonable(P≤0.05). Healthcare agencies're-spondents have higher scores for than pharmaceutical companies'ones. CONCLUSIONS:The current drug medical insurance nego-tiation mechanism shows good overall effect and runs smoothly. But there are still some shortages,such as collected information the preparation stage is not sufficient;the procedures of patients taking the drug is complicated;negotiating parties do not have equal status;the fund is not paid to the pharmaceutical enterprise timely;evaluation is not perfect.

Objective To investigate the prevention and treatment effects of Compound Kushen Injection on acute radiation esophagitis. Methods Eighty-two eligible patients with esophageal cancer were randomly divided into the treatment group (41 cases) and the control group (41 cases). All the patients received radiotherapy. Throughout the course of radiotherapy, patients in the treatment group received Compound Kushen Injection, and patients in the control group received Kangfuxin Liquid. Occurrence time and level of radiation esophagitis, and dosage of painkillers were observed. Results Different degrees of acute esophageal toxicity were observed in the two groups. The occurrence rate of high level (degree III and degree IV) acute radiation esophagitis was 7.3%(3/41) in the treatment group, and 31.7%(13/41) in the control group. There was significant difference between the two groups (P<0.05). The dosage of the analgesic drug (Fentanyl Transdermal System) in the treatment group was far less than the controlled group (P<0.001). Conclusion Compound Kushen Injection could decrease the incidence rate of acute radiation esophagitis, and reduce the high-level esophagitis and the dosage of the analgesic drug, which can help the completion of radiation.

Objective To observe analgesia effect of morphine hydrochloride and hydromorphone hydrochloride in patients after transurethral resection of prostate. Methods Patients after transurethral resection of the prostate (TURP) were randomly divided into 2 groups, morphine hydrochloride group (n=45) and hydromorphone hydrochloride group (n=47). Analgesia, sedation efficacy and adverse reactions were evaluated at 6 and 24 h after they received epidural postoperative analgesia by using VAS score and Ramsay score. Results In 6 h, hydromorphone hydrochloride group had a better pain tolerance and feeling than morphine hydrochloride group (P<0.05) [(2.9±0.3) score vs.(1.3±0.2) score, (2.4±0.3) score vs. (0.9±0.2) score].However, in 6-12 h, the results were on the contrary (P<0.05) [(3.4±0.3) score vs.(5.4±0.3) score, (3.3±0.2) score vs. (5.7±0.4) score].After 24 h, there was no difference between the two groups (P>0.05).There were no differences in adverse reactions between the two groups ( P>0. 05 ) . Conclusion Hydromorphone has a better effect than morphine in epidural analgesia in 6 h.

Objective:To investigate the clinical value of Octreotide plus Ulinastatin in the treatment of severe acute pancreatitis(SAP)in elderly patients.Methods:From May 2016 to February 2019, 124 elderly SAP patients admitted to the gastroenterology department of our hospital were enrolled and divided into the combination therapy group and the control group, with 62 patients in each group.The combination therapy group was treated with Octreotide and Ulinastatin, while the control group was treated with Octreotide alone.Serum leukocyte count, C-reactive protein(CRP), interleukin(IL)-6, tumor necrosis factor(TNF)-α and amylase levels were monitored before and 1, 3, 5, 7 and 14 days after treatment by automated biochemical analysis and enzyme-linked immunosorbent assays.The pain grade scale, APACHE-Ⅱ score and efficacy evaluation were analyzed for the two groups 7 days after treatment.The time to oral refeeding and length of hospitalization were compared between the two groups, and related complications during the treatment were recorded.Complications and the recurrence of pancreatitis within 1 year were followed up in both groups.Results:There was no statistically significant difference in serum white blood cell count, CRP, amylase, IL-6 and TNF-α levels between the two groups before treatment(all P>0.05). Serum white blood cell count, CRP and TNF-α levels had significant differences( t=3.735, 2.851 and -2.147, P=0.036, 0.029 and 0.043)and serum amylase and IL-6 levels had no significant difference( P>0.05)between the two groups 3 days after treatment.All the above parameters had significant differences between the two groups 7 days after treatment( t=3.624, 2.918, -2.166, 2.684 and -2.593, P=0.023, 0.011, <0.001, 0.015 and <0.001). Serum amylase, IL-6 and TNF-α levels had significant differences( t=-3.515, 4.627 and -3.189, all P<0.001)and serum white blood cell count and CRP had no significant difference(all P>0.05)between the two groups 14 days after treatment.There were significant differences in visual analogue scale(VAS)and APACHE-Ⅱ score between the two groups 7 days after treatment( t=-2.346 and -3.245, P=0.021 and 0.002). On the 7th day after treatment, the effectiveness rate was 79.0%(49/62)in the combination therapy group and 61.3%(38/62)in the control group, with a significant difference between the two groups( χ2=4.661, P=0.031). Compared with the control group, time to oral refeeding and hospitalization length were shorter in the combination therapy group than in the control group(6.72±1.87 d vs.7.65±1.69 d, 11.23±2.98 d vs.13.85±3.42 d, t=-2.868 and -4.565, both P<0.05). There were significant differences in the incidences of infectious pancreatic necrosis, gastrointestinal adverse reactions and organ failure between the combination therapy group and the control group(11.3% or 7/62 vs.25.8% or 16/62, 43.5% or 27/62 vs.21.0% or 13/62, 1.6% or 1/62 vs.11.3% or 7/62, χ2=4.324, 7.233 and 4.810, P=0.038, 0.007 and 0.028). There were significant differences in mean length of time without complications and recurrence between the combined group and the control group(10.25±3.26 months vs.8.72±3.73 months, 10.69±2.51 months vs.9.62±2.92 months, Log Rank χ2=7.463 and 4.589, P=0.006 and 0.032). Conclusions:Octreotide combined with Ulinastatin can effectively alleviate local symptoms, slow clinical progression, reduce the risk of complications, decrease the recurrence rate and promote early recovery in elderly SAP patients.

This study aimed to construct recombinant adenovirus expressing Epstein-Barr nuclear antigen 1 (EBNA1) against nasopharyngeal carcinoma (NPC). The C-terminal region fragment of the ebna1 gene of Epstein-Barr virus was amplified from the standard strain B95-8 by polymerase chain reaction (PCR). The gene fragment was inserted into the pDC316 shuttle plasmid using the EcoRI and BgIII restriction enzyme sites. The pDC316-ebna1 shuttle plasmid and pBHG helper plasmid were cotransfected into HEK293 cells after sequencing. The soluble protein was extracted from HEK293 cells, which caused apparent cytopathic effects. The transcription and expression of the ebna1 gene were confirmed using flow cytometry and Western blotting. rAd-ebna1 titers were measured by the TCID50. rAd-ebna1 was injected into BALB/c mice at a dose of 2 x 10(8) VP per mouse, EBNA1 epitope-specific responses were measured at 1st, 2nd, 4th and 8th weeks post-immunization. The target fragment of ebna1 (939 bp) was obtained by PCR, and was in consensus with the sequence from the standard strain B95-8. Cytopathic effects were observed after the pDC316-ebna1 shuttle plasmid and pBHG helper plasmid were cotransfected into HEK293 cells. rAd-ebna1 was successfully recombined in HEK293 cells. EBNA1 protein was detected in HEK293 cells, rAd-ebna1 titers reached 10(8) TCID50/mL. Specific responses to CD4+ epitopes of EBNA1 were detected in the immunized mice. In conclusion, rAd-ebna1 was successfully constructed and induced specific responses to CD4+ epitopes of EBNA1 in immunized mice.

OBJECTIVETo explore the application value of the high-frequency ultrasound examination of the normal adult sciatic nerve.

METHODSThe high frequency ultrasound was used to examine 60 cases ,a total of 120 normal adult sciatic nerve (28 males and 32 females ranging in age from 19 to 38 years old, averaged 23.8 years old). The age between men and women, height and weight showed no significant difference. The cross-sectional scanning and longitudinal scanning, if necessary, Panoramic Imaging were conducted. The cross section area of sciatic nerve was measured at the hip line, the middle of the thigh, the edge of the popliteal fossa, and the relationship betwen the sciatic nerve and surrounding muscle group was observed in each cross-section. Probe was rotated 90 degree to display the long axis of sciatic nerve, to get the longitudinal section along the long axis from top to bottom. So the sciatic nerve in the vertical axis and the surrouunding muscles was displayed by above method combined with panoramic imaging. The data of coss-sectional area of sciatic nerve were obtained at the central of hip line, the middle of the thigh, the edge of the popliteal fossa, and then were divided into different groups by gender and sides to do statistical analysis.

RESULTSThe applicatic nerve in thigh can be clearly displayed by high-frequency ultrasound in this group of 60 people with 120 nerves, but low display rate of sciatic nerve in hip, approximatley 31.4% (21/66). The longitudinal section of the sciatic nerve displayed as the banded isoechoic or slightly hyperechoic, parallel partial hyperechoic line could be seen in it; in the cross-section, it showed a clear edge of the sieve-like isoechoic or slightly hyperechnie, which could be oval ,trapezoidal, triangular and irregular in shape; the sciatic nerve bad visible passive movement and shape change when muscle contracted. There were statistically significant differences of cross-sectional area of sciatic nerves at the hip line ,the middle of thigh and edge of the popliteal fossa between 56 sciatic nerves in 28 males and 64 sciatic nerves in 32 females (P< 0.05); but there were no significant differences between left and right sides (P>0.05).

CONCLUSIONHigh frequency ultrasound can be used as the first choice of the sciatic nerve when an imaging method preferred.

Objective To observe the therapeutic effectiveness and safety of autologous peripheral blood stem cell transplantation (APBSCT) for poor-risk non-Hodgkin lymphoma (NHL). Methods Ten patients with poor-prognosis NHL were enrolled from October 2003 to October 2008 in our institute. Ten patients were treated by APBSCT with CY+TBI conditioning regimen (Two patients of them were treated by Double-APBSCT with MEC conditioning regimen). Results Hematopoietic reconstitution was observed in all patients.The time of neutrophil count ≥0.5×109L and platelet≥20×109/L were at day 10 (range: 7-14) and day 16 (range: 10-37), respectively. All patients achieved complete remission (CR) after transplantation. Severe toxicity and transplant related mortality were not observed. After a median follow-up of 24 (10-84) months,seven cases were in event-free survival and three cases relapsed. One of three relapsed patients died from progression of disease, the other was still alive after treatment. Conclusion APBSCT in the treatment of patients with poor-prognosis NHL is a safe, convenient and efficient treatment.
