The DNA fragments of ag85b、esat-6、hsp65、mpb64 and ag85b-esat-6、hsp65-esat-6、mpb64-esat-6 were amplified by PCR and SOE technique.These seven fragments were inserted into pCDNA3.1(+)vector to construct recombinant plasmids pCA、pCE6、pCH、pCM、pCAE、pCHE and pCME.The seven plasmids were transfected into SP2/0 cell in vitro to detect the expression of target genes.BALB/c mice were intramuscularly vaccinated with the seven plasmids and the control vector pCDNA3.1(+)and PBS respectively.The serum antibodies and the spleen lymphocyte proliferation(SLP)and secreted IFN～? of spleen were tested.The results of indirect ELISA showed the levels of antibodies in all recombinant plasmids groups were significantly higher than the two control groups(P

PURPOSE: X-ray film over responds to low-energy photons in relative photon beam dosimetry because its sensor is based on silver bromide crystals, which are high-Z molecules. This over-response becomes a significant problem in clinical photon beam dosimetry particularly in regions outside the penumbra. In intensity modulated radiation therapy (IMRT), the radiation field is characterized by multiple small fields and their outside-penumbra regions. Therefore, in order to use film dosimetry for IMRT, the nature the source of the over-response in its radiation field need to be known. This study is aimed to verify and possibly improve film dosimetry for IMRT. MATERIALS AND METHODS: Modulated beams were constructed by a combination of five or seven different static radiation fields using 6 MeV X-rays. In order to verify film dosimetry, we used X-ray film and an ion chamber were used to measure the dose profiles at various depths in a phantom. In addition, in order to reduce the over-response, 0.01 inch thick lead filters were placed on both sides of the film. RESULTS: The measured dose profiles showed a film over-response at the outside-penumbra and low dose regions. The error increased with depths and approached 15% at a maximum for the field size of 15X15 cm(2) at 10 cm depth. The use of filters reduced the error to 3%, but caused an under-response of the dose in a perpendicular set-up. CONCLUSIONS: This study demonstrated that film dosimetry for IMRT involves sources of error due to its over-response to low-energy photons. The use of filers can enhance the accuracy in film dosimetry for IMRT. In this regard, the use of optimal filter conditions is recommended.

Malignant mixed mullerian tumor (MMMT) is rare and has pathologically carcinoma and sarcoma components. Among them, primary peritoneal MMMTs are extremely rare, and their proper treatment and prognosis are not well-known. We experienced a case of primary peritoneal origin MMMT, so we report it with a brief review of the literatures.

The goal of the immunologic maneuvering for organ transplantation may be the donor specific immune tolerance rather than non-specific immunosuppression. Although DST is one of the most extensively studied methods for donor specific immune hyporesponsiveness, it is not widely used in recent years because of possible sensitization and overall improvement of graft survival without DST. Several human and animal studies showed that -24h DST with concomitant cyclosporine administration improved graft survival. -24 DST may not induce adverse sensitization that preclude subsequent transplantation and the procedure is simple and does not delay the operation in living donor transplantation. Between Feb. 1994 and Jan. 1997, 33 patients received 100-200ml of fresh whole blood from the kidney donor 1 day before transplantation. Twenty donors were living related and 13 donors were non- related. Mean age was 40(22-52). Two patients was diabetic. All but one received primary allograft. Cyclosporine and prednisolone were the primary immunosuppressants that started 2-3 days before transplantation. Acute rejection occurred in 11 recipients(33.3%). Acute rejection tended to occur earlier. Eight of 11 first episodes were within 3 days post- transplant, which were all recovered by either steroid pulse or OKT3. Mean follow up was 35 months. Two patients died with functioning graft. Three-year graft survival rate was 93.9%. There was no immunologic graft loss. We conclude that -24h DST may be a valuable option of immune modulation for renal transplantation with no demonstrable adverse reaction. It's beneficial effect needs to be confirmed by a larger controlled study.

BACKGROUND: Multiple studies have reported that allografts are acceptable alternatives to autografts for anterior cruciate ligament (ACL) reconstructions. Our clinical practice allows patient involvement in graft decision-making. This study examined the patients' preference for graft selection and the factors affecting their decision. METHODS: Patients scheduled to undergo an ACL reconstruction surgery (n = 129) at a university medical center in Korea were enrolled in this study. Information leaflets with graft descriptions were provided prior to hospital admission, and the patients were allowed to choose one of two surgical graft types. The patients were asked to complete a questionnaire that reflected their decision-making processes, and the patients' trends and factors affecting their choice of graft were analyzed based on their responses. RESULTS: Most patients (54.3%) selected autografts for the ACL reconstruction. The surgeon's explanation was the most important factor affecting the final patient decision followed by the information derived from Internet searches. Patients who derived the majority of their understanding of the graft types from the Internet chose allografts at significantly higher rates. CONCLUSIONS: Patient graft selection is a reasonable way of designating the type of surgical procedure. Most patients selected autografts for their ACL reconstruction. However, patients who performed significant Internet-based research tended to prefer allografts.

OBJECTIVE: To provide clinical information for the best diagnosis and treatment of primary malignant cervical lymphoma based on the information obtained from these cases. METHODS: Between 1989 and 2006, six women with primary malignant cervical lymphoma were diagnosed and treated at our institution. Data were obtained from their medical records and were retrospectively analyzed. RESULTS: The mean patient age at the time of diagnosis was 63 (range 19-74). The chief complaint was vaginal bleeding in five women and the voiding difficulty for one woman. five of six patient had the cervical lesions (erosion and tumoral mass), while the other was non specific cervical findings. The Papanicolaou test was performed on three women, one of whom was HSIL. All six patients were confirmed with cervical lymphoma through the pathologic diagnosis. Surgical treatment (radical hysterectomy with bilateral salpingo- oophorectomy, pelvic lymph node dissection, and para-aortic lymph node dissection) was performed in one case, simple hysterectomy with complementary chemotherapy in two, and chemotherapy in one. Two patients refused treatment. Among four patients treated, one experienced recurrence in an ovary and the others have remained in remission. CONCLUSION: Primary malignant cervical lymphoma is a rare malignancy. Physicians can miss early detection of this disease because of its 'silent' symptoms and very low incidence. The accumulated data regarding this tumor can make it easy to detect at an early stage, thereby allowing it to be successfully treated. Further studies should be conducted to obtain further information regarding the cervical lymphoma.

OBJECTIVETo survey the reporting quality of traditional Chinese medicine (TCM) case reports published in recent years and understand the common problems. The assessment results would lay the foundation for the development of recommendations for case report in Chinese medicine.

METHODSThis survey determined the reporting quality of cases with Chinese herbal decoction, Chinese proprietary medicine, acupuncture, moxibustion and other traditional therapies published in 20 core medical journals of China by searching the China Academic Journals Full-text Database from 2006 to 2010. Fifty survey items in 16 domains were used to determine the reporting quality. One point was assigned to each item (Yes=1 point; No=0 point), and total score was 50 points. The domain of treatment was assessed independently, ranging from 2 to 9 items for different TCM interventions.

RESULTSThe total of 1,858 case reports, covering 3,417 cases were included to analyze from 13 out of 20 core medical journals of China. There were 74.8% of them did not identify the nature of study in title, while 73.9% did not comprise an abstract. Incomplete reporting was found in discussions/ comment, and only 38.9% had made recommendations or take-away messages. Figures and tables were infrequently used. Three cases cited the full names of patients, but without declaring that any consent was obtained. Over 90% reported the symptoms and signs of TCM, and characteristics on tongue and pulse, but less than 50% did mention other medical history and diagnostic rationale. More than 90% treatments of the included cases were herbal decoction, with clear reporting on the ingredients and dosages. However, the reporting rate of the dosages of each ingredient was just 48.4%. Almost none reported the quality control of crude herbs, manufacturers and lot numbers of herbal proprietary medicine. Besides, advices and precautions on diet, emotions and living were rare to be illustrated.

CONCLUSIONSystematic reporting recommendations are urged to develop for improving the contents and format of case reports in TCM.

Case reports are valuable clinical evidence in traditional Chinese medicine (TCM). However, the general reporting quality is suboptimal. A working group comprising 20 members was set up to develop systematic recommendations on case report in Chinese medicine (CARC). The working group (CARC group) developed a primary checklist based on reviewing the general reporting quality of case reports in TCM and thorough internal discussion. Two-round consensus process had been carried out among clinical experts, evidence-based medicine methodologists, medical journal editors and clinical practitioners with designated questionnaire embedded with the primary checklist. In total, 118 participants from 17 provinces of China and Korea completed the questionnaires. Their feedback was analyzed and discussed by the CARC group. The checklist was amended accordingly, and the final version, comprising 16-item, is presented here. Under the framework of CARC recommendations, the reporting quality of case reports in TCM can be improved.

Vasoactive intestinal peptide(VIP) is a 28-amino acid peptide, which may cause secretory diarrhea by stimulating the production of adenylate cyclase. Neuroendocrine tumors, secreting vasoactive intestinal peptide (VIP), are almost always of a pancreatic in origin. However, a pheochromocytoma may produce several neuropeptides, containing VIP, as they are considered to be neuroendocrine tumors. A 57-year-old woman, who presented with chronic watery diarrhea, hypokalemia, weight loss and a left adrenal mass, is described. Histologically, the tumor was diagnosed as a pheoch-romocytoma, with ganglioneuronal differentiation, and was histochemically confirmed to produce a vasoactive intestinal polypeptide. A left adrenal VIP-producing pheochromocytoma was successfully resected. After surgery, her diarrhea subsided and the electrolytes, affected neuroendocrine hormone levels, blood pressure and blood sugar level were normalized.

Malaria remains a serious public health problem in Shandong Province, China; therefore, it is important to explore the characteristics of the current malaria prevalence situation in the province. In this study, data of malaria cases reported in Shandong during 2012-2014 were analyzed, and Plasmodium species were confirmed by smear microscopy and nested-PCR. A total of 374 malaria cases were reported, 80.8% of which were reported from 6 prefectures. Of all cases, P. falciparum was dominant (81.3%), followed by P. vivax (11.8%); P. ovale and P. malariae together accounted for 6.4% of cases. Notably, for the first time since 2012, no indigenous case had been reported in Shandong Province, a situation that continued through 2014. Total 95.2% of cases were imported from Africa. The ratio of male/female was 92.5:1, and 96.8% of cases occurred in people 20-54 years of age. Farmers or laborers represented 77.5% of cases. No significant trends of monthly pattern were found in the reported cases. All patients were in good condition after treatment, except for 3 who died. These results indicate that imported malaria has increased significantly since 2012 in Shandong Province, especially for P. falciparum, and there is an emergence of species diversity.
