Objective To explore the safety of fat reduction treated by non invasive focused ultrasound.Methods A randomized double-blind and negative control clinical trial was carried out on the excess fat of 40 subjects' abdomen by a JCS-01 non-invasive focused ultrasound device.Subjects received treatments with the device on day 1 and day 7.Observations on the area treated and inquiries on feelings were conducted during treatments.Before the first treatment and 14 days after the treatment,laboratory examinations were performed,including liver function,blood lipid tests,etc.Results 40 subjects participated in the trial and 36 subjects (18 each in both treatment and control groups) accomplished 2 times of treatments,all followed-up and laboratory examinations.During the process of treatments,4 subjects in the experimental group complained about feelings of tepidity or pricking.One subject on blood test of triglyceride showed slightly higher than her early normal result,which fell to the normal level at reexamination.Conclusions Subjects treated by non-invasive focused ultrasound at the area of no more than 500 cm2 every time and at an interval of 6 days manifest little changes on the blood test results,with slightly local reactions but no complaints during follow-up.

Objective cyclin D1 gene plays a significant role in regulating cell cycle progression.Suppression of cyclin D1 protcin expression can effect on cellular proliferation,distribution of cell cycle and apoptosis.This study was to determine whether this effect also existed in chronic leukemia ceil line K562 by inhibiting the expression of cyclin D1 protein through RNA interference in vetro.Methods Plasmid vectors expressing small hairpin RNA (shRNA) targeting at cyclin D1 gene were constructed and transfected into K562 cells by chitosan,cyclin D1 protein was examined by using Western blot analysis.Inhibition of cellular proliferation was evaluated hy soft agar colony formation assay.The cell cycle and apoptosis were determined by flow cytometry.Results Expression of cyclin D1 protein was markedly down-regulated and capability of colony formation was suppressed after transfection with pshRNA-419 and pshRNA-575 at 48h.Down-regulation of cyclin D1 protein could effect on distribution of cell cycle arrested at G_0/G_1 phase and markedly induce apoptosis of K562 cells.But there had no above biological effects ob- served after transfection with blank vector and control vector of m-pshRNA-790.Conclusion Down-regulation of cyclin D1 expression can inhibit growth of K562 cells,and effect on distribution of cell cycle arrested at G_0/G_1 phase.The primary results suggest that cyclin D1 gene might serve as an effective target for the treatment of leukemia.

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously associated with higher 1-, 2-, and 3-year overall survival rates (OR1-year=3.98, 95% CI 2.87-5.51, P<0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P<0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P<0.00001) than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone (OR=13.86, 95% CI 8.04-23.89, P<0.00001). And there was a significant difference in local recurrence rate between two different kinds of treatment (OR=0.24, 95%CI 0.14-0.44, P<0.00001). Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy. TACE-plus-RFA treatment was associated with a higher response rate (RR) than the TACE-alone treatment (OR=3.90, 95% CI=2.37-6.42, P<0.00001). TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease (SD) rate (OR=0.38, 95% CI=0.11-1.26, P=0.11). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.

AIM: To retrospectively analyze selection of operation, surgery effect, complications and treatment methods of super high myopia combined with rhegmatogenous retinal detachment( RRD) .
METHODS:A total of 47 cases(47 eyes) with the super high myopia patients combined with RRD who accepted scleral buckling of external pressure, vitrectomy combined silicone oil filling, or intravitreous gas injection were chosen in our hospital from Jan. 1, 2011 to Jan. 1, 2016. Best corrected visual acuity ( BCVA), intraocular pressure, retinal reattached rate, closure rate of holes and the postoperative complications of patients in half year were analyzed.
RESULTS:Half a year postoperation, BCVA of twenty-four cases underwent vitrectomy combined silicone oil filling were improving(71%), and eight cases with scleral buckling surgery were enhanced ( 73%) . Statistical test showed the surgical treatment could significantly improve patients'eyesight, especially PPV with silicone oil, but the BCVA of patients with scleral buckling of external pressure in this study had no obvious significance according to the rank sum test. Compare with other surgery, pars plana vitrectomy( PPV ) combined silicone oil filling had more complications, such as high intraocular pressure and diplopia.
CONCLUSION: The therapy of super high myopia patients with rhegmatogenous retinal detachment need many years' clinical experience, surgical skill of clinician and according to the number, the shape and the site of the retinal holes and area of detached retina, they need to choose the right means of surgery, and timely deal with postoperative complications, in order to improve the patients' postoperative retina, reset rate and visual function.

Diabetic retinopathy(DR), one of the most common retinal vascular disease, is one of the causes of blindness for people over the age of 50.In the early stage of DR, microvascular cells are damaged, expand, start to leak, form micro hemangioma, then show occlusion, and non-perfusion area come into being, eventually form new blood vessels because of ischemia and hypoxia of retina.Illness develop into proliferative diabetic retinopathy(PDR).With the aggravation of the disease, PDR can cause the formation of fibrovascular membrane, the more serious fibrillation of epiretinal membrane, resulting in traction retinal detachment(tRD).Present studies suggest that aquaporins, the essential component of new blood vessels, including aquaporin 1 and aquaporin 4, play a significant pole in the development of diabetic retinopathy, causing the destruction of blood retinal barrier, inducing retinal edema, even macular edema, and participating in the formation of retinal angiogenesis.

OBJECTIVETo reveal the quality variation of polysaccharides, triterpenoids and proteins in spores and fruiting bodies of Ganoderma lucidum from producing areas, different varieties, harvesting parts and periods, and wall-breaking treatments.

METHODSpores and fruiting bodies from varieties of Longzhi No. 1 and Hunong No. 1 were collected as test samples, together with wall-broken spores sold in domestic main producing areas. The anthrone-sulfuric acid colorimetric method was used to determine the content of total polysaccharides. The vanillin-glacial acetic acid-perchloric acid colorimetric method was used to determine the content of total triterpenoids. The Lowry method was used to determine the content of total proteins.

RESULTThe content ranges of total polysaccharides, total triterpenoids, and total proteins from 6 domestic main producing areas were 0.40% - 2.25%, 1.36%-3.15% and 0.74% -1.91% respectively. The content ranges of total polysaccharides, triterpenoids, and proteins in the fruiting bodies from 2 varieties cultured in Zhejiang were 0.25% -1.42%, 0.44% -1.42% and 1.82% -3.67% respectively. In addition, the ranges of samples from wall-unbroken spores were 0.41% - 0.91%, 0.09% - 0.12%, 0.78% - 0.90% respectively and wall-broken spores are 1.03% - 2.25%, 1.89% - 3.15%, 0.96% - 1.04% respectively.

CONCLUSIONThere are significant differences in the contents of main chemical ingredients of wall-broken G. lucidum spores saled in the markets. The samples from Zhejiang contain high content of total polysaccharides and triterpenoids, and samples from Fujian contains more proteins. Between the 2 major varieties cultured in Zhejiang, Longzhi No. 1 contains higher content of triterpenoids, but Hunong No. 1 has more polysaccharides. Contents of triterpenoids and polysaccharides from wall-broken spores are much higher than those of fruiting bodies. The stipes from fruiting bodies contains more polysaccharides than those of the pileus, while the triterpenoids contents are higher in the pileus than stipes. The pileus and stipes collected in the second year contain higher content of polysaccharides than the first year's samples, but the contents of triterpenoids are lower. Wall-breaking treatment would significantly improve the extraction and dissolution rate of total triterpenoids and polysaccharides.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.
