Objective To study the clinical efficacy and adverse reactions of the preoperative neo-adjuvant chemotherapy with oxaliplatin plus fluorouracil and calcium folinate (FOLFOX) in the treatment of advanced gastric carcinoma that was difficult to undergo radical operation. Methods We enrolled 16 patients with advanced gastric carcinomas that were unable to undergo radical operation admitted to our hospital from April 2008 to October 2009. The neo-adjuvant chemotherapy regimen was oxaliplatin 130 mg/m~2 for first one, fluorouracil 500 mg/m~2 and calcium folinate 200 mg/m~2 from first day to fifth day,and one treatment course was three weeks and the patients underwent two courses.The changes of the primary lesion and the adverse reactions of the patients were observed. Results Carcinomas of 13 patients were degraded after the treatment, of which, 11 patients underwent radical resections after 4-6 weeks after operation.There were two cases of complete remission (CR) , 10 cases of partial remission (PR), three cases of stable disease(SD) and one case of progress disease(PD) , and the total effective rate was 75.0% (12/16). Adverse reactions included bone marrow suppression, diarrhea, nausea and vomiting and paresthesia, which were relieved after appropriate symptomatic treatment. Conclusions Neoadjuvant chemotherapy with FOLFOX can improve the resection rate of the advanced gastric carcinoma that is unable to undergo radical resection, and the patients' tolerability to this regimen is favorable.Thus, the regimen is worthy of generalizing.

Genuine medicinal materials with special characteristics of Traditional Chinese Medicine (TCM), is recognized as high quality medicine. Both ancient records and modern research considered that the origin is an important reason for the formation of genuine medicinal materials. However, blindly transplanting of genuine medicinal materials has led to the quality decline and counterfeit medicines appeared in production or sale progress, which may increase the risk of accidents in TCM. Frequent accidents emerged in Chinese herbal affects its export. What's more, it is a great threat to the medication safety in TCM clinical. There is an urgent need to implement traceability systems of TCM, which could provide convenient information record and traceability of TCM circulation. This paper reviews a variety of technical methods for genuine medicinal materials traceability, and proposed the establishment of genuine medicinal materials traceability system based on two-dimensional code and network database.

AlM:To evaluate the clinical efficacy of intravitreal injection of ranibizumab combined with macular grid photocoagulation for diabetic macular edema ( DME) .METHODS:Totally 60 eyes ( 60 patients ) with DME were randomly divided into 2 groups: 30 eyes of simple injection group underwent intravitreal injection of ranibizumab, and 30 eyes of combined treatment group underwent intravitreal injection of ranibizumab and macular grid photocoagulation 1wk later. The best corrected visual acuity ( BCVA ) , central macular thickness ( CMT ) measured by optical coherence tomography ( OCT ) and postoperative complications were observed.
RESULTS:ln simple injection group, the BCVA after operation were separately 0. 390 ± 0. 075 (4wk), 0. 367 ± 0. 088 (8wk) and 0. 319 ± 0. 064 (12wk), the CMT after operation were separately 221. 63 ± 112. 34μm (4wk), 337. 73±99. 56μm (8wk) and 432. 92 ± 100. 46μm (12wk), which were much better than pre-operation. But during follow-up, the BCVA presented down trend and the CMT was on the rise slowly. ln combined treatment group, the BCVA after operation were separately 0. 385 ± 0. 036 (4wk), 0.382±0.079 (8wk) and 0.377±0.097 (12wk),the CMT after operation were separately 249. 77 ± 106. 55μm (4wk), 270. 40 ± 92. 88μm (8wk) and 275. 84 ± 97. 34μm (12wk ), which were satisfactory and steady during follow-up, better than simple injection group (P<0. 05).CONCLUSlON:lntravitreal injection of ranibizumab can effectively improve visual acuity and decrease central foveal thickness for patients with DME, combining with macular grid photocoagulation can ensure therapeutic effects steady and permanent.

OBJECTIVE:To provide the scientific evidence and reference for improving medical reform. METHODS:Based on background ofSanming Medical Reform,self-designed questionnaires were used to investigate the cognition and satisfaction of local patients. The results of investigation were analyzed statistically. RESULTS:A total of 275 paper questionnaires were sent out and all were collected;345 electronic questionnaires were sent out by Wechat and all collected. Among 620 questionnaires,372 valid questionnaires were collected with effective rate of 60.00%. More patients(31.45%)thought the cost of treatment decreased, and less (22.31%) thought the cost increased. The proportion of high-income people who thought cost reduced was significantly higher than the proportion of low-income people (P=0.018). 27.42% of patients believed shortage of drugs,and tertiary hospi-tals were more prone to drug shortage than other medical institutions(P=0.062). The patients'satisfaction with medical staff and healthcare reform were both high(86.56% and 79.03%),but the satisfaction of rural patients was lower than that of urban patients (P=0.051). Understanding of patients onSanming Medical Reformwas in low level. Only 20.70% of the patients fully under-stood or generally understood ofSanming Medical Reform. The patients who thought the skills of medical staff were improved (40.32%)were more than those who thought the skills of medical staff were reduced(5.91%). CONCLUSIONS:Most patients are satisfied withSanming Medical Reform,and agree the achievements;but some problems are not solved,such as the shortage of some drugs,lack of grass-roots medical personnel,not understand medical policy.

Objective:To study the causes of misdiagnosis of patients with POEMS syndrome and to discuss the clues for its early diagnosis.Methods:The clinical and laboratory data of 26 inpatients with POEMS syndrome,who were treated in Changhai hospital over the last decade,were retrospectively analyzed.Results:The misdiagnosis rate of our group was 100%. The misdiagnosis was made in(3.31?0.97)hospitals and in(3.31?0.93)clinical departments;the misdiagnosis period was (19.42?10.86)months and it had been misdiagnosed as 18 other diseases.The initial symptoms included polyneuropathy in 21 (80.8%)cases,edema of lower extremity in 22(84.6%)cases,and body weight loss in 8(30.8%)cases.The typical clinical symptoms included polyneuropathy in 26(100%)cases and organomegaly in 24(92.3%).Two cases had newly-identified uterine hypertrophy,one had adrenal gland hypertrophy,and one had gastric wall thickening mimicking advanced gastric cancer.Hypothyroidism,impotence,skin pigmentation and sclerosis occurred in 76.9%(20/26),60%(6/10),92.3%(24/ 26)and 65.4%(17/26)cases,respectively.Monoclonal plasma cell proliferation was documented in 18(81.8%);M proteins were positive in 14(63.6%)cases by serum immunofixation,and only 2(9.1%)cases also positive by serum protein electrophoresis.One patient was positive of M protein by urine immunofixation and one had abnormal infiltration of plasma cells in the gastric wall.Lymph node biopsy were performed in 8 patients and 3 were found to have Castleman disease;the other 5 cases had lymphocyte infiltration,with 3 complicated with plasma cell proliferation.Nerve biopsy in 4 cases all revealed axonal degeneration and one patient complicated with demyelination.Bone marrow biopsy in 5 cases revealed plasmacytosis in 2 cases and myeloma in one.Excessive radioactivity resorption was found in 10 of the 16 cases(62.5%)and abnormal plasma cells were detected in 2 cases by bone aspiration guided by radioisotope bone scan.Conclusion:Misdiagnosis of POEMS syndrome is very common.Polyneuropathy,edema of lower extremity and body weight loss are the common early symptoms of POEMS syndrome. Early diagnosis can be made by having an intimate knowledge of the progression of the disease and by detecting M protein through various approaches.
