Pancreatic endocrine tumors (PETs) are very rare and are divided into functional and nonfunctional tumors.Their clinical manifestations vary,and imaging diagnosis easily led to missing diagnosis and misdiagnosis for PETs.With the development of MRI technology,especially application of fat suppression techniques,diffusion weighted imaging (DWI) and dynamic enhanced magnetic resonance imaging (DEMRI) are of great value on imaging diagnosis and differential diagnosis for PETs.The clinical data of 13 patients with PETs who were admitted to the Central Hospital of Enshi Autonomous Prefecture from June 2007 to December 2011 were retrospectively analyzed,and their MRI imaging features were studied.The diagnostic values of MRI,especially DWI and DEMRI for PETs were investigated.

Objective To investigate clinical significance of plasma D-dimer (D-D),fibrinogen (FIB) and fibrin/fibrinogen degradation product (FDP) in patients with chronic obstructive pulmonary disease (COPD).Methods The level of plasma D-D,FIB and FDP in 150 patients with COPD and 80 healthy persons were detected,and compared.Results The level of plasma D-D,FIB and FDP in COPD patients were significantly higher than those in healthy persons[(2.16 ± 0.61) mg/L vs.(0.55 ± 0.04) mg/L,(5.88 ± 1.52) g/L vs.(3.12 ± 0.35) g/L,(7.18 ± 1.63) mg/L vs.(3.62 ± 1.55) mg/L],there were significant differences (P ＜ 0.01).Conclusion Monitoring the level of plasma D-D,FIB and FDP in COPD patients can provide reliable basis in hypercoagulable state and primary and secondary hyperfibrinolysis.

Heroin addicts were treated with acupuncture, Chinese herbs, and acupuncture plus Chinese herbs respectively, their effects were compared with that of Western medicine.The scores of withdrawal symptoms were observed continuously for 20 days. The effect of acupuncture was better than that of Western medicine 48 hours after the withdrawal treatment (P＜ 0.05), and better than that of other three methods 72 hours after the withdrawal treatment, (P ＜ 0.01). Acupuncture, Chinese herbs, and acupuncture plus Chinese herbs have the detoxification effects of varying degrees, in particular acupuncture' effect was the best. But all the therapies could not completely improve the withdrawal symptoms in the first 3 days of treatment, and acupuncture plus Chinese herbs had no synergetic effect in treating withdrawal symptoms.

Objective To evaluate mortality associated with simultaneous bilateral or staged bilateral TKA, and better understand the risks involved in the simultaneous versus staged bilateral procedures.Methods A systematic review was conducted, following an a priori protocol, according to the methods recommended by the Cochrane Musculoskeletal Group in the Cochrane Collaboration. Eligible studies were identified in PubMed (1990-2010), OVID MEDLINE (1990-2010), and the Cochrane library, concerning postoperative complications of bilateral or staged bilateral total knee arthroplasty. All of the English-language abstracts were obtained, and retrieval words including bilateral total knee arthroplasty, staged total knee arthroplasty, and total knee arthroplasty, etc. An extensive analysis was then performed to identify articles fulfilling the inclusion criteria for the study. The details of the reported data were extracted and evaluated by two reviewers independently. Data analyses were conducted with Stata 10.0. Results Six studies met our inclusion criteria for review. The combined results showed that the prevalence of mortality[OR=2.925, 95% CI (2.352, 3.638)], mortality 30 days postoperatively[OR=5.078, 95% CI (2.192, 1 1.763)]and mortality in 70 years or older patients[OR=4.087, 95% CI (1.947, 8.582)]were statistically higher in the population that had undergone simultaneous TKA compared with staged TKA. Conclusion Compared with staged bilateral TKA, simultaneous bilateral TKA might carries a higher potential risk of postoperative mortality. Patients should be aware of this information when deciding whether to proceed with simultaneous bilateral TKA. Further well-designed and large-scale randomized controlled trials are required to confirm these findings.

Objective To observe the effects of Fuyanshu Capsule on phenol mucilage-induced endometritis rats and the possible anti-inflammation mechanism of the therapeutic effects.Methods Chronic endometritis in rats was induced by injection of phenol mucilage suspension into the uterus.Sixty female SD rats were randomly divided into 6 groups,namely,sham-operation group (distilled water,10mL/kg),model group,Jinji capsule group (0.65 g/kg),and Fuyanshu Capsule groups (1.8 g/kg,0.9 g/kg and 0.45 g/kg).After the rats were treated 28 days with corresponding medicine by intragastric administration,the pathology of the endometrium and changes of tumor necrosis factor α(TNF-α)and interleukin-2 (IL-2)levels were detected to evaluate the effects of Fuyanshu Capsule. Results Fuyanshu Capsule (1.8 g/kg and 0.9 g/kg)ameliorated the body weight reduction caused by endometritis in rats.Fuyanshu Capsule (1.8 g/kg,0.9 g/kg and 0.45 g/kg)reduced the ratio of the swelling uterus and ovaries to body weight of the rats.It ameliorated obviously the hyperplasia,necrosis and degeneration of endometrial epithelia and infiltration of inflammatory cells.The capsule (1.8 g/kg)decreased the serum IL-2 level in the rats with phenol mucilage-induced endometritis. Conclusion The anti-inflammatory effect of Fuyanshu Capsule on chronic endometritis induced by phenol mucilage in rats may be related to the decrease of IL-2 level.

Objective To investigate the expression of insulin-like growth factor 2 receptor(IGF-2R)induced by hypoxia and serum deprivation(H/SD)in cultured neonatal rat cardiomyocytes in vitro.Methods Cultured neonatal rat cardiomyocytes were randomly divided into control group and H/SD group.Expression of IGF-2R mRNA was measured by RT-PCR and real time RT-PCR.Level of IGF-2R protein was measured by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,the expression of IGF-2R mRNA increased significantly (P ＜0.01)in cardiomyocytes cultured in H/SD condition for 12 h and 24 h,and IGF-2R protein was upregulated in cardiomyocytes cultured in H/SD condition for 24 h(P ＜0.05).Conclusion H/SD may induce IGF-2R expression,and IGF-2R may potentially explain the mechanism of cardiomyocyte damage induced by ischemia.

Objective To observe the clinical effect of the club exercise designed ourselves on the prevention of should-hand syndromeafter stroke. Methods 100 stroke patients in early stage, whose motor function of upper limb were lower than Grade Ⅲ evaluated byBrunnstrom assessment and without shoulder pain and swelling of hand, were randomly divided into control group (n=50) and observationgroup (n=50). All of them received routine rehabilitation therapy, and the observation group received club exercise in addition. The incidenceof shoulder pain, the active range of motion of shoulder, the motor function of upper limb and activities of daily living (ADL) of 2groups were evaluated before and 2 courses (60 d) after treatment. Results There was no statistical difference between 2 groups before thetreatment (P>0.05). After 2-course treatment, the incidence of shoulder pain was significantly lower in the observation group than in the controlgroup (P<0.001), the active range of motion of shoulder, motor function of upper limb and ADL were significantly better in the observationgroup than in the control group (P<0.001). Conclusion The club exercise can prevent the pain of shoulder joint, increase the activerange of motion of shoulder joint and improve the motor function of upper limb and ADL in patients after stroke.

Objective To explore the effect of acupuncture on stroke patients in hemiplagic spasm period.Methods63 stroke patients in hemiplagic spasm period were randomly divided into the electro-acupuncture group(n=31) and control group(n=32).All patients of two groups received routine rehabilitation training,but those of the electro-acupuncture group were added with electro-acupuncture at "Zusanli"(ST36).The composite spasticity scale(CSS) score,H/Mmax and muscular compliance of two groups before and after treatment were observed and compared.ResultsThe CSS scores and H/Mmax and grading gastrocnemius muscular compliance of the electro-acupuncture group were superior to that of the control group(P<0.05～0.01).ConclusionAcupuncture can decrease muscular tension and increase motor function of stroke patients in hemiplagic spasm period.
