With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

OBJECTIVETo evaluate the replication and encapsidation of HBV mutants with the truncated C gene.

METHODSThe HBV mutants with the truncated C gene were constructed by molecular cloning and PCR-based deletion in vitro. The replication and encapsidation of HBV mutants were investigated by Southern blotting, PCR and real-time fluorescence PCR respectively after transfecting the HBV mutants plasmid into HepG2 cells by using liposome.

RESULTSThe C-truncated HBV mutant vectors were constructed successfully and confirmed exactly by clone sequencing and enzymes digestion. The C-truncated HBV mutants were replication defective, however, all types of HBV DNA could be detected positive in the cytoplasm and supernatant after co-transfecting the C-truncated HBV mutants plasmid and the helper constructs into HepG2 cells. The C-truncated HBV mutants were proved to produce 3-40 folds more progeny DNA than that of the wild-type HBV by DNA quantitative assay.

CONCLUSIONThe C-truncated HBV mutants are replication-deficient and could not replicate and encapsulate in the hepatocytes when transfected solely, however, the progeny HBV-variant viruses are encapsidated more effectively to secrete into supernatant when co-transfected with the helper construct which lacks part of 5 prime-proximal HBV RNA packaging signal Epsilon.

OBJECTIVETo investigate the efficacy and toxicity of neoadjuvant chemotherapy with paclitaxel and carboplatin or cisplatin for patients with locally advanced cervical cancer.

METHODSA total of 70 patients with locally advanced cervical cancer were treated with neoadjuvant chemotherapy with paclitaxel and carboplatin or cisplatin in our department from July 2007 to May 2010. The stage distribution among the patients included 45 stage IB2, 21 stage IIa, and 4 stage IIb. Of the 70 patients, 6 were G1, 26 were G2, 32 were G3, and the rest 6 patients were not histologically classified. Sixty-five patients had squamous cell carcinoma, 3 had adenocarcinoma, and 2 patients had adenosquamous cell carcinoma. The clinicopathological parameters were analyzed, and their impact on tumor response were investigated.

RESULTSOf the 70 patients, 14 (20.0%) showed a complete response, 37 (52.9%) had a partial response to chemotherapy, making an overall response rate of 72.9%. Sixty-eight (95.7%) patients underwent surgery, and among them 12 (17.1%) pathological CR were identified. Eleven (16.2%) patients were found to have lymph node metastasis after surgery. Response rates of stage Ib2 and IIa patients were 73.7% and 52.3%, respectively, P<0.05. Patients with SCC exhibited a better response rate than patients with adenocarcinoma and adenosquamous cell carcinoma (73.8% vs. 60.0%). Initial tumor volume, histological classification and cycles of neoadjuvant chemotherapy were not significantly correlated with the response rate.

CONCLUSIONPaclitaxel and carboplatin or cisplatin regimen is a promising therapy with definite short-term efficacy, can improve the resection rate with tolerable side effects, and is an applicable option of treatment for patients with locally advanced cervical cancer in the neoadjuvant setting.

OBJECTIVETo further understand the clinical features of non-gastric mucosa-associated lymphoid tissue (MALT) lymphoma and investigate its suitable treatment.

METHODSA retrospective survey of 57 non-gastric MATL lymphoma patients pathologically confirmed in our hospital from 1999 to 2011.

RESULTSThe median age was 58 years (range 14-86 years). Common presenting sites of non-gastric MALT lymphoma included lungs and upper respiratory tract (17 patients, 29.8%), intestinal tracts (16 patients,28.1%), orbital and ocular adnexal (7 patients, 12.3%), and salivary glands (8 patients, 14.0%). Stage Ⅰ-Ⅱdisease presented in 35 patients (61.4%), stage Ⅲ-Ⅳ disease in 22 patients (38.6%). A total of 26 patients had nodal involvement and 7 patients multiple organ involvement. Regimens included surgery alone, chemotherapy alone, surgery followed by chemotherapy or chemoradiotherapy. The complete response (CR) rate was 66.0% and the overall response rate 85.7%. At a median follow-up of 52 months, the 5-year overall survival (OS) and the 5-year progression free survival (PFS) were 91.6% and 77.7%, respectively. The 5-year survival rate of surgery, chemotherapy, surgery+chemotherapy, surgery + chemotherapy + radiotherapy groups were 87.5%, 100.0%, 90.2% and 100.0%, respectively, without significant differences. The 5-year PFS of the four groups were 62.3%, 80.0%, 90.2% and 75.0% respectively.

CONCLUSIONNon-gastric MALT lymphoma is characterized by disseminated onset, favorable response to treatments and good outcomes. There is no statistically significant difference in the overall survival of the various treatments. But the recurrence rate of surgery alone is relatively high (22.3%).

Objective To study the epidemic tendency of emerging influenza A (H1N1) in mainland China, and to explore the different patterns of spread on the disease under the following contexts: (1) To stop the temperature screening program at the border areas of the country; (2)To stop measures of prevention and control on those identified cases and their close contacts; (3) To strengthen programs for the foreign immigrants on 'home quarantine'. Methods Under relevant parameters and information on the transmission link from different reference data, the patterns of influenza spread were simulated by Monte Carlo method. Results The temperature screening on border could inhibit the transmission of influenza A (H1N1) to some extent, so that after 3 months the cumulative number of cases will be reduced by 21.5% (1718 cases) and transmission speed of influenza A (H1N1) in mainland China will be delayed by about 4 days. Furthermore, taking positive measures of prevention and control could efficiently slow down the epidemic, so that after 3 months the cumulative number of cases will be reduced by 93.4%(about 90 thousand cases) and it would be delayed by about 15 days if influenza A (H1N1) spreads to the whole country. In addition, if the immigrants were able to practise quarantine measures consciously by themselves at home the effect of prevention and control against influenza A(H1N1) would be more significant. If 30%, 60% and 90% of immigrants would take quarantine measures home consciously, after 3 months the cumulative number of cases will be reduced by about 15% (about 940 cases), 34% (about 2230 cases) and 64% (about 4180 cases), respectively. Also, influenza A (H1N1) spreads to the whole country will be delayed by about 4 days, 10 days and 25 days, respectively. It is difficult to curb fully the development of the epidemic by taking existing control measures, and influenza A (H1N1) may spread to almost all provinces after about 3 months. Conclusion The effects of existing prevention and control measures were objectively assessed and the results showed the necessity and effectiveness of these measures against the transmission of influenza A (H1N1) , in the mainland of China.

OBJECTIVETo evaluate the clinical utility of capsule endoscopy in diagnosing small bowel disease.

METHODSA retrospective review of 155 cases undergone capsule endoscopy examinations from September 2002 to March 2007 in our hospital were performed. Gastric and small bowel transit time, patient tolerability, number of complete and incomplete examinations, and examination findings were evaluated.

RESULTSA total of 155 cases were reviewed, and 159 times of capsule endoscopy examination were finished. Of the 155 patients, 97 suffered from obscure gastrointestinal bleeding, 42 abdominal pain, 6 abdominal discomfort, 4 diarrhea, and 6 body check. The capsule endoscopy examination for the entire small bowel were finished in 93.1%(148/159)cases. All the patients had no discomfortable feeling during the examinations. The capsule endoscopy remained in the stomach for an average of 65.5 min(1 to 335 min). The mean transit time in the small bowel was 282.2 min(45 to 524 min). The diagnostic yield of capsule endoscopy was 78.6%(125/159). Vasculopathy was present in 43.4% patients, enteritis in 28.3%, submucous knot in 10.1%, diverticulum of small intestine in 8.2%, and small intestine tumor in 5.7%. Other findings consisted of polyposis of small intestine, foreign objects and parasite. The diagnostic yield of obscure gastrointestinal bleeding by capsule endoscopy was 89.7%, and of abdominal pain was 73.8%.

CONCLUSIONSCapsule endoscopy is safe and well tolerated. Capsule endoscopy is a valuable diagnostic tool in the evaluation of occult small bowel disease, especially for obscure gastrointestinal bleeding.
