Objective To investigate the clinical efficacy, the toxicity and side reactions of interventional chemoembolization with FOLFOX4 regimen through both hepatic artery and superior mesenteric artery, i.e. dual access technique, in treating primary hepatocellular carcinoma. Methods Between November 2010 and March 2013 at authors’ hospital, a total of 21 patients with advanced primary hepatocellular carcinoma (the study group) were treated with FOLFOX4 regimen by using dual access interventional technique. FOLFOX4 regimen included hepatic arterial infusion of 5-fluorouracil 400 mg/m2, hepatic arterial chemoembolization with iodipin and oxaliplatin 85 mg/m 2, intravenous administration of calcium folinate 200 mg/m2 IV on the first and second day, trans-superior mesenteric artery continuous infusion (lasting for 22 hours) of 5 -Fuorouracil 600 mg/m2 on the first and second day. During the same period other 21 patients with primary hepatocellular carcinoma were selected (used as the control group) to receive conventional hepatic arterial chemoembolization. In both groups, the treatment was repeated after 4-6 weeks. The therapeutic effect and the toxicity and side reactions were evaluated after the second treatment. Results The effective rate for the study group and the control group was 61.9% and 28.6% respectively, and the median survival time for the study group and the control group was 14.7 months and 9.4 months respectively. The differences in the effective rate and the median survival time between the two groups were statistically significant (P = 0.030 and P = 0.034). The occurrence of toxicity and side reactions, such as digestive tract reactions and the damage of liver function, in the study group were strikingly lower than those in the control group. Conclusion Through dual approach of hepatic artery and superior mesenteric artery catheterization, interventional chemoembolization with FOLFOX4 regimen is outstandingly effective for primary hepatocellular carcinoma, meanwhile, the side effects are very slight.

Objective To explore the effect of sling exercise therapy (SET) for improving the balance and walking ability of patients with incomplete paraplegia.Methods The 37 patients were randomly divided into two groups:19 patients in the observation group and 18 cases in the control group.Both groups were given conventional rehabilitation training,including bridge training on the mat,kneeling position training,sit-stand training and orthosis walking training.The observation group was additionally provided with sling exercise therapy with multi-point,muhi axis sling suspension supine,prone with a neutral lumbar spine,supine with pelvic elevation and in a lateral position like an arch.Before the treatment and 6 weeks after the treatment,trunk control tests (TCTs) were administered.The Berg balance scale (BBS) and Holden's walking function classification were used to assess the subjects' balance and walking ability.Results There were no significant differences in the two groups' average TCT and BBS scores before the treatment.After 6 weeks of treatment the average scores of both groups had increased significantly,with a significantly bigger increase observed in the observation group.After the treatment,the average Holden classification of the observation group was significantly superior to that of the control group.Conclusion SET in addition to conventional rehabilitation training can significantly improve the balance and walking ability of patients with incomplete paraplegia.It is worthy of application in clinical practice.

Objective To investigate the relationship of triglycerides/high-density lipoprotein (TG/HDL C) ratio with coronary heart disease (CHD) and its severity.Methods 158 patients with CHD were enrolled in this study.Patients were divided into 4 groups according to the selective coronary arteriography:the control group,single-vessel CHD group,double-vessel CHD group,multiple-vessel CHD group.The relationship between multiple risk factors and CHD was analyzed by stepwise multiple regression.The severity of coronary artery stenosis was analyzed by Gensini scoring system.Results TG/HDL-C ratio was elevated in patients with coronary artery stenosis as compared with the control group [(1.8±1.0) vs.(1.7±1.4),t=2.68,P＜0.05].TG/HDL-C ratio was elevated along with the severity of CHD.TG/HDL-C ratio was elevated in multiple-vessel C HD group as compared with the control group by ANOVA analysis (P＜0.05).Stepwise multiple regression showed that multiple-vessel CHD was positive related with total cholesterol (TC),LDL-C and TG/HDL-C ratio (β value:0.326,0.339,0.158,respectively,all P＜0.05).Conclusions TG/HDL C ratio is related with multiple vessel CHD,but it does not have more clinical significances than other indicators.

Malignant pheochromocytomas are rare tumors that arise from chromaffin tissue, and the diagnostic criterion of malig-nancy is based on the development of metastases. In the case a patient suffers the tumor with liver, lung and bone metastases. However, the test results of tumor markers, gastroscopy, chest and abdominal CT, and PET-CT examination are hard to make a definite diagnosis. The patient was finally diagnosed with malignant pheochromocytoma with liver, lung and bone metastases following the needle biopsy of liver and underwent the excision of a right adrenal pheochromocytoma. Therapeutic standard for the malignant pheochromocytomas is not available so far. It is reported that chemotherapeutic CVD regimen (cyclophosphamide, vincristine, and daecarbazine) and suni-tinib may be effectual in the alike cases. The patient received two cycles of CVD and one cycle of sunitinib, nevertheless, slow progres-sion of the disease remained after the treatment. The results of multi-disciplinary treatment have suggested that 131I-MIBG may just be a choice for this patient.

Objective:To observe any effect of combining motor imagery therapy (MIT) with repeated transcranial magnetic stimulation (rTMS) for improving upper limb motor functioning after a stroke.Methods:Ninety stroke survivors were randomly divided into a control group, an MIT group and a combination group, each of 30. All received conventional rehabilitation therapy, while the MIT group additionally received MIT and the combination group received the MIT along with 1Hz rTMS applied over the M1 region of the contralateral cortex. Before and after 4 weeks of treatment, everyone′s upper limb functioning was quantified using the Fugl-Meyer assessment scale (FMA) and the Hong Kong version of the hemiplegia upper limb function test (FTHUE-HK). Motor evoked potentials (MEPs), cortical latency (CL) and central motor conduction time (CMCT) were also recorded.Results:After the treatment the average FMA and FTHUE-HK scores of all three groups had improved significantly. The average CL and CMCT were significantly shortened. Compared with the control group, the average upper limb FMA score and FTHUE-HK scores of the treatment group were significantly higher. The combination group showed a significant improvement in its average MEP cortical latency and CMCT values.Conclusions:MIT therapy alone can improve the upper limb motor functioning of stroke survivors, but it is more effective in combination with rTMS.

A retrospective study was conducted on one patient with postmenopausal hyperandrogenism. The postmenopausal female patient was found with significant hyperandrogenism ( total testosterone 6. 4 nmol/ L) and hirsutism, with normal adrenal androgen ( dehydroepiandrosterone-sulfate ) level. Computed tomography and ultrasound did not detect any ovarian and adrenal mass. Positron emission tomography revealed without high metabolic region, either. Ovarian and adrenal vein catheterization did not reveal any positive result. Obviously, ovary-derived hyperandrogenism was highly suspected, but the patient still refused any surgical exploration. After a trial of a single dose of gonadotropin releasing hormone analogue(GnRHa) triptorelin, increased testosterone level returned to normal along with decreasing level of gonadotropin. Multiple doses were needed for maintenance of testosterone at normal level with the intervals of 2 ～ 12 months. This response to the treatment was consistent with that of gonadotropin dependent hyperandrogenism.

Mammography has played an essential role in the screening and treatment of breast cancer. However, the application of X-rays will also increase the risks of breast cancer while improving its detection rate. Moreover, the risks will increase with an increase in the radiation dose. Since the glandular tissue in breasts is sensitive to radiation, the evaluation of the average glandular dose (AGD) in mammography has attracted considerable international attention. Compared to relatively mature dosimetric studies on traditional two-dimension mammography and digital breast tomosynthesis, the method for the dose evaluation of the new cone beam CT for breasts are still subjected to research. This paper reviews and explores the current status of studies on the assessment method and relevant influencing factors of AGD under different types of mammography equipment.

We think that all the methods of puncturing into the skin to prevent and treat diseases are belong to acupuncture science. In spite of its basic theory of meridian and acupoint, anatomy and physiology have been important parts of modern acupuncture science. "Dry needling", however, is limited to trigger point theory. As for the positions, acupuncture is applied mainly at acupoints, involving in skin, muscles, tendons, vessels and nerves; while "dry needling" is used mostly at muscles. The needles of acupuncture are in various lengths and diameters and its manipulations are abundant, including the traditional skills and the achievements of modern science and technology research, such as electroacupuncture. It is different from the "dry needling" with the single tool and manipulation. Thus, acupuncture is suitable for a large range of syndromes, but "dry needling" is mainly for fascia muscularis pain and other related disorders. The acupuncturists need to embrace Chinese and western medicine, which is more rigorous than the training for "dry needling" practitioners. Based on the above reasons, we consider "dry needling" as part of acupuncture science, and it is a method during the modern development of traditional acupuncture.

Objective: To compare the efficacy of intra-articular injection of autologous platelet-rich plasma (PRP) with that of sodium hyaluronate for patients with knee osteoarthritis (KOA). Methods: Fifty KOA patients were randomly divided into a PRP group (n=25) and a sodium hyaluronate group (n=25). Those in the PRP group were injected intra-articularly with 5 ml of autologous PRP every 2 weeks for 6 consecutive weeks, while the sodium hyaluronate group was given intra-articular injections of 2 ml of sodium hyaluronate once a week for 6 weeks. Both groups performed isokinetic strength training three times a week for 6 weeks. Before as well as 6 weeks, 3 months, 6 months and 12 months after the treatment, both groups were followed and evaluated using the Western Ontario and McMaster University osteoarthritis index (WOMAC). A Biodex System 4 isometric muscle strength testing system was used to evaluate the knees′ peak torque (PT) in flexion and extension, total power (TW), and average power (AP). Results: Before the treatment there were no significant differences in pain, stiffness or average WOMAC score between the two groups. Afterward significant improvement was observed in the pain, stiffness and WOMAC scores of both groups. Compared with the sodium hyaluronate group, significantly greater decreases in the average WOMAC pain score were observed in the PRP group after the different intervals. That was also true of the average stiffness scores and the overall average WOMAC scores after 6 and 12 months. The flexor and extensor PT, TW and AP at the angular velocities of 60°/s and 90°/s also improved significantly in both groups after 6 weeks and 12 months, with the improvement of the PRP group significantly greater than that in the control group at the same time points. Conclusion Intra-articular injection of either autologous PRP or sodium hyaluronate can effectively alleviate the clinical symptoms of KOA when combined with isokinetic strength training. However, PRP is the more effective. Its use is worthy of clinical application and promotion.
