Scoliosis surgery includes fusion and non-fusion techniques.Fusion technique includes posterior fusion technique and video-assisted anterior thoracoscopic fusion.Non-fusion technique is suitable for children patients with growing potential of the spine.It includes growing rod,vertical expandable prosthetic titanium rib(VEPTR),U-shape screw,and multi-vertebral wedged osteotomy(for severely rigid scoliosis).Short term outcome from these techniques has been encouraging,but medium and long term outcomes are still need investigation.

The metabolic syndrome is a complex disorder of several metabolic abnormalities,which represents a risk factor of type 2 diabetes mellitus and cardiovascular diseases.Insulin resistance seems to play a significant role in pathoyenesis of metabolic syndrome.Many issues concerning definition,pathophysiology and optimal treatment of metabolic syndrome are reviewed in this article.

Objective: To prepare exenatide-loaded poly (lactic-co-glycolicacid)(PLGA) microspheres and to evaluate their release behavior in vitro. Methods: Exenatide-loaded PLGA microspheres were prepared by W/O/O method using PLGA as vectors. An HPLC approach was established to determine the content and in vitro cumulative release. The physicochemical characteristics of microspheres, including the mean diameter, morphology, drug entrapment efficiency and loading efficiency, were evaluated. Results: The prepared microspheres were well-shaped, with a mean diameter of (51.2±1.97) μm. The drug loading was (4.50±0.13)% and the encapsulation efficiency was (96.5±2.68)%. The first day burst release was (13.19 ± 1.39)% and the in vitro 28-day-cumulative-release was (88.6 ± 0.73)%. Conclusion: The W/O/O method is stable, controllable, and repeatable for preparing exenatide-loaded microspheres using biodegradable polymers PLGA as the vector; the microspheres yield a one-month continuous release and have a bright future in treatment of diabetes mellitus.

Nucleotide binding oligomerization domain (NOD)-like receptor protein 3, NLRP3) inflammasomes regulate the secretion of caspase-1, interleukin-18 (IL-18), IL-1β, and other cytokines, and participates in aging. In recent years, it has been found that NLRP3 inflammasomes are abnormally activated in aging heart and vessels, and inhibition of NLRP3 inflammasomes can alleviate heart aging and vascular aging. This review summarizes the research of NLRP3 inflammasome in heart and vascular aging, and the related drugs to promote the discovery of the mechanism of NLRP3 inflammasome in heart and vascular aging and the development of related drugs.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To study the MR imaging appearances in a series of patients with stages T1N0M0 and T2N0M0 peripheral cholangiocarcinoma of the liver and to differentiate these tumors from hepatic metastases and from other solitary necrotic nodules.Methods A retrospective analysis was carried out on MR examinations of 26 patients with histologically confirmed choangiocarcinoma.The imaging findings were compared with those of 2 non-choangiocarcinoma groups including 23 patients with metastasis and 29 patients with solitary necrotic nodules confirmed with surgery,biopsy or follow-up imagings.Statistical analysis included Chi-square test or Fisher's exact test and the use of receiver operating characteristic (ROC) curves.Results Peripheral choangiocarcinomas in stages T1N0M0 and T2N0M0 were less than or equal to 3 cm in diameter (10 patients,≤2 cm and 16 patients,2 cm).Common findings for cholangiocarcinoma were defined margins (n =22,85％),slightly high signal on T2W1 (n =23,88％),patchy enhancement (n =20,77％),“fill-in” enhancement from periphery toward the center (n =21,81％) and diffuse hypointensity at the periphery and center of tumor (n =9,35％).There were significant differences (P ＜ 0.05) between the choangiocarcinoma group and the non-cholangiocarcinoma group in the above imaging findings.The area under the curve (Az) for differentiating peripheral cholangiocarcinoma was 0.896 ± 0.037,sensitivity was 84.6％,and specificity was 86.5％.Conclusions Our data indicated that MRI features of peripheral cholangiocarcinoma in stages T1N0M0 and T2N0M0 could be determined.MR imaging,when combined with clinical and biochemical data,provided reliable information to diagnose peripheral cholangiocarcinoma.

As a member of PARP superfamily, PARP3 shares a high homology with PARP1 and PARP2, which are all DNA-dependent enzymes that are catalytically activated by DNA strand breaks.Compared to PARP1 and PARP2, PARP3 exerted some special properties in tissue expression pattern and biological function.The evidence has shown that PARP3 could be activated by DNA double strand breaks and special DNA single strand breaks and synthesize mono(ADP-ribose) (MAR) covalently attached to target proteins including itself.PARP3 plays an important role in DNA double strand breaks, DNA single strand breaks, activation of PARP1 and development of nervous system.It has been reported that PARP3 is associated with glioma and breast cancers.In this review, PARP3 structure, activation mechanism, biological function and its relationship with diseases will be presented.

500 thousands people died from gastric cancer in China over 2015,shortage of clinical medicines and therapeutic methods is one of the reasons for the high mortality.Tumor immunotherapy is the hottest area of research over the past decade,whose success in hematological malignancies makes people raised their confidence to “cure” cancer.In recent years,gastric cancer immunotherapy research has made some achievements,while clinical outcomes still need improvement.In this paper, the progress of clinical research of common immunotherapeutic drugs and methods in several fields of gastric cancer research are reviewed to discuss the development prospects of immunotherapy for gastric cancer .

Objective: To observe the clinical therapeutic effects of acupuncture at the bony clefts in combination with tuina therapy in the treatment of sprains and strains of minor joints at the four extremities. Methods: Ninety cases of sprains and strains of minor joints at four extremities [including metacarpophalangeal (metatarsophalangeal)joints] were divided randomly into three groups by the consulting order. Acupuncture group, in which 30 cases were treated by acupuncture at the bony clefts; tuina group, in which 30 cases were treated by tuina therapy; and observation group, in which 30 cases were treated by acupuncture at the bony clefts and tuina therapy. The treatment was given 6 times a week as one course of treatments, and the therapeutic effects were observed after 2 courses of treatments. Results: The cure rates of the observation group, the acupuncture group and the tuina group reached 50.0%, 20.0% and 16.7% respectively, and the total effective rates reached 93.4%, 70.0% and 73.3% respectively. There were statistical significance between the observation group and the acupuncture and tuina groups (P<0.05); while there was not a statistical difference between the acupuncture group and the tuina group. It was indicated that the therapeutic effect of the observation group was better than that of the acupuncture group and the tuina group. Conclusion: Acupuncture at the bony clefts in combination with tuina therapy is quite effective in the treatment of sprains and strains of metacarpophalangeal (metatarsophalangeal) joints.
