OBJECTIVETo invesitigate the clinical effects of percutaneous closed reduction and cannulated screw internal fixation combined with external fixation in the treatment of unstable pelvic fractures.

METHODSFrom April 2006 to May 2009,29 patients with pelvic fractures of rotatory instability were treated with closed reduction and screw internal fixation combined with external fixation. There were 19 males and 10 females with an average age of 31 years old (ranged from 19 to 53 years). Based on the Tile classification,17 cases were type CI and 12 case were type C2. Tornetta standard and Majeed score were used to evaluated the clinical effect after operation.

RESULTSAll patients were followed up from 10 to 24 months with an average of 16 months. There were no nerve injuries and other organ injuries, only one case of infection was found and it was cured with wound dressing. Time of fracture union was from 14 to 18 weeks with the mean of 16.2 weeks. No loosening, slippage or breakage of the screw were found. According to the Tornetta standards,14 cases obtained excellent results, 10 good, 4 fair and 1 poor. The Majeed score was 87.2 ± 11.3, 16 cases got excellent results, 9 good and 4 fair.

CONCLUSIONClosed reduction and screw internal fixation combined with external fixation is an effective way to treat unstable pelvic fractures with Tile type C1 and Tile type C2.

Physical training induces beneficial adaptations,but long excessive exercise may lead to severe damage to the skeletal muscles,liver,heart,kidneys and immune functions. Over the past few decades,health scholars have been searching for natural components that can prevent or improve the damage induced by hyperkinesis. The mechanisms of organ damage induced by long overtraining include immunosuppression,metabolism disorder,hormone disturbance,oxidative damage, etc. Natural poly-saccharides have interventional effects on these injuries,possibly by improving immunity,regulating metabolism and ameliorating free radical damage.

OBJECTIVETo investigate the possible mechanism of the electroacupuncture for improvement of learning and memory in rats of Alzheimer's disease (AD).

METHODSSixty Wistar rats were randomly divided into a normal group, a normal saline group, a model group, a western medication group and an electroacupuncture group, 12 rats in each group. The AD rat model was established by injecting Streptozocin (STZ) into lateral cerebral ventricle, except the rats in the normal saline group injecting Normal Saline with the same dose and in normal group with no injection. The western medication group was treated with intragastric administration of Memantine, and in the electroacupuncture group, the electroacupuncture was given at "Baihui" (GV 20), "Dazhui" (CV 14), "Taixi" (KI 3), "Shenshu" (BL 23), "Zusanli" (ST 36), once each day, 7 days for a course, and lasted for 4 courses. The other three groups were fed in routine way and without any treatment. The learning and memory ability was assessed by Morris water maze and the expression of Abeta positive cells of the hippocampus and superoxide dismutase (SOD) activity were determined by immunohistochemistry and visible spectrophotometer colorimetry.

RESULTSCompared with the normal group and the normal saline group, the Abeta protein expression was significantly increased in the model group (both P < 0.01), and the SOD activity was obviously decreased (both P < 0.01). After treatment, as compared with the model group, the Abeta protein expression was significantly decreased (both P < 0.01), and the SOD activity was obviously increased (both P < 0.01) in the electroacupuncture group and western medication group.

CONCLUSIONElectroacupuncture treatment can reduce the Abeta protein expression and increase the SOD activity of the hippocampus so as to improve learning and memory ability in the AD rats.

OBJECTIVETo study the influence of neuro-psychological factors on the effect of acupuncture in the treatment of Bell's palsy and the overall prognosis in patients.

METHODSFifty patients with Bell's palsy were randomized into the treatment group and the control group, and they were treated with manipulated and non-manipulated acupuncture, respectively. Scorings by subjective perceptive scale of acupuncture, Cartel personality test, and Hamilton Anxiety Scale were performed and the curative effect was assessed according House-Brackmann grading standards.

RESULTSThe total effective rate of acupuncture was 78.0% (39/50), and that of manipulated acupuncture was better than that of non-manipulated acupuncture [89.2% (25/28) vs. 63.6% (14/22), P < 0.01]. Visual analogue scoring for perception of "Deqi", evaluated either by patients or by doctors, showed that the scores was higher in the treatment group than in the control group (P < 0.01). Cartel personality test (16PF) found that patients with personality factors of sociability, intellectuality, excitability, braveness, and independence were capable of getting "Deqi" more easily, there existed a significant correlation between personality factors and curative effect. By Hamilton Anxiety Scale scoring, 92.0% (46/50) of the patients were found being in an anxiety state, and the efficacy of treatment was negatively correlated with the degree of anxiety (r = -0.9491, P < 0.05).

CONCLUSIONNeuro-psychological factors put great influence on the efficacy of treatment for Bell's palsy, multiple measures, such as drug-therapy, acupuncture, psychological intervention, rehabilitation therapy, etc., should be taken in combination for improving patients' prognosis.

Objective To investigate the endoscopic findings and treatment of gastrointestinal neu-roendocrine neoplasms.Methods Endoscopic manifestation and treatment were analyzed retrospectively in 72 patients who were diagnosed as having gastrointestinal neuroendocrine neoplasms by endoscopy and pathol-ogy from May 2011 to December 2014.Results In 72 patients of gastrointestinal NEN,rectum was most commonly involved (48 patients,66.7%),followed by the stomach (16 patients,22.2%),duodenum, esophagus and the ileocecal valve.There were certain features in rectal neuroendocrine neoplasms under endoscopy,mostly manifested by submucosal tumors.But gastric,esophageal,and small intestine NEN man-ifestations showed various forms,without specific typical features,and easy to be misdiagnosed.Some patients diagnosed as having NEN G1 or G2 underwent EMR,ESD or laparoscopy combined with endoscopy resection.Patients diagnosed as having NEN G2 or neuroendocrine carcinoma by pathology received surgical resection,chemotherapy or palliative treatment.All 50 patients underwent endoscopic treatment successful-ly.Perforation occurred in one duodenal bulbar G1 patient during ESD.No bleeding occurred during and after the operation.All patients after treatment were followed up for 15.6 +13.2 months on average with no recurrence or metastasis.Conclusion Manifestations of gastrointestinal neuroendocrine neoplasms vary under endoscopy.Some tumors that locate in mucosa or submucosa with diameter less than 1cm can be resec-ted through EMR or ESD.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.
