Objective To analyze the MRI imaging feature and the clinical feature of pituicytoma. Methods The clinical data and imaging feature of 10 patients with pituicytoma who were proved histologically were retrospectively studied. Visual disturbances disorder and headache were the main complaints of all patients. One patient had sexual function decline. All patients were given the examination of MRI and showed saddle area were occupied. Results Most of pituicytoma was circular or oval morphologically. Pituicytoma located at suprasellar region in 4 patients, in the sellar in 2 patients and over the sellar region in 4 patients.In them, cystic change occured in 1 patient. In most of the cases, the tumor showed isointensity on T1WI, isointensity or slightly hyperintensity on T2WI. After injection of contrast medium, the tumor showed homogeneous enhancement in early stage. Pathological markers:S-100, and vimenlin indicated 100%positive;glial fibrillary acidic protein(GFAP), synaptophysin (SYN) and epithelial membrane antigen(EMA) indicated 50% positive. Six patients′serum endocrine function test:the levels of serum total triiodothyronine (TT3), total thyroxine (TT4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (FSH), luteinizing hormone (LH) had different degrees of reduction in 4 patients, and these index were normal in 2 patients. Conclusions On MRI, pituicytoma has certain characteristics which might help clinical diagnosis combined with the clinical manifestation and endocrine function tests.

The in vitro cell culture experiment was conducted to study the effect of Danqi Piantan capsule (DPC) and DPC dislodge the antelope horn with artificial bezoar double (DPCBD) on nerve regeneration and blood vessel regeneration and preliminarily investigate the possibility of substituting antelope horn in DPC with artificial bezoar. In this experiment, rats were randomly divided into 5 groups: the blank serum control group, the model group, DPC groups (0.306 g x kg(-1) x d(-1), the same below), DPC remove of antelope horn (DPCRA) groups and DPCBD groups. Brain microvascular endothelial cells cultured in vitro (BMEC), astrocytes and neural stem cells (NSC) were co-cultured to simulate neurovascular unit, label neurons with microtubule associated protein III (β-tubulin III) antibody and lable astrocytes with glial fibrillary acidicprotein (GFAP). ELISA was used for the detection of the content of BMEC lactate dehydrogenase instrument method (LDH), the inverted phase contrastmicroscope was adopted to observe the formation of BMEC tube like structure, the number of leukocytes and leukocytes adherent to BMEC were counted under the microscope, the expression levels of β-tubulin III and the ratio of GFAP positive cells was detected with inimmunofluorescence, and RT-PCR method was used to detect NGF, BDNF, VEGF and VEGFr-2 mRNA. According to the result, compared with the model group, both DPC and DPCBD can reduce LDH leakage, promote the formation of BMEC tube like structure, inhibit leukocytes and their adhesion to BMEC, increase the β-tubulin III positive cell differentiation proportion (P < 0. 01), reduce the proportion of GFAP positive cells (P < 0.01), increase the expressions of co-cultured NGF, VEGF, BDNF and VEGFr-2 mRNA to a certain extent, with the most significant difference on NGF and VEGF mRNA expressions (P < 0.05) and the same efficacy in both groups. DPCRA groups showed less impact on all indexes than that of DPCBD and DPC groups. The same efficacy of DPCBD and DPC on nerve regeneration and angiogenesis suggested that antelope horn in DPC can be substituted by artificial bezoar.

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 evaluate the hearing function of pilots under physical examination for modification to equipment of high performance aircraft,using pure tone audiometry(PTA) and distortion product otoacoustic emission(DPOAE).Methods Analyzed were all the results of PTA and DPOAE of 75 pilots (150 ears) which accepted physical examination for modification to equipment of high performance aircraft in our department from March 2008 to February 2009.75 cases were divided into two groups according to their flight time.The difference between these two groups was studied.Results According to the Equipments of Physical Constitution for Flying Persons of Air force,PLA,all 75 pilots passed the ENT assessments as being qualified for flying.Of all 150 ears,abnormal DPOAEs were obviously higher than that of abnormal PTA tests.128 ears had normal PTA results.92 ears had normal DPOAE results.36 ears (27.6&) showed abnormal DPOAEs at one or more frequencies,especially at 1,3 and 4 kHz.22 ears had abnormal PTA results.20 ears had noticeable V or U shaped thresholds at 3 kHz and/or 4 kHz.The DPOAE amplitudes showed similar curves.The other two ears showed depressions at all frequencies,in both PTA and DPOAE tests.No statistically significant difference was found between the two groups in DPOAE.But statistical difference was found in DPOAE at 4 kHz compared with other frequencies.No statistically significant differences were found between the two groups in DPOAE amplitudes at 1,2,3 and 4 kHz.but at 6 and 8 kHz.Conclusion The application of DPOAE test helped find pilots who were on the early stage of noise-induced hearing loss.These pilots were the most important objects for us to follow up.

Objective To evaluate the potential activity ofSaccharomyces boulardii as an adjuvant to triple therapy for Helicobacter pylori infection,so as to forecast the probable effectiveness of Saccharomyces boulardii in the eradication of Helicobacter pylori and the adverse reaction.Methods A total of 120 patients who received gastroscopy and tested positive for Helicobacter pylori infection were divided into standard triple therapy group and Saccharomyces boulardii group with 60 cases each by random digits table method.Patients were randomized to receive one week standard triple therapy,supplemented with Saccharomyces boulardii in Saccharomyces boulardii group.Saccharomyces boulardii was taken 500 mg per day for one week.All adverse reactions were recorded during the treatment period.13C or 14C urea breath test was performed at four weeks after the end of triple therapy to evaluate the situation of Helicobacter pylori eradication.Results Helicobacter pylori eradication rate in Saccharomyces boulardii group was higher than that in standard triple therapy group [80.00％ (48/60) vs.73.33％ (44/60)],but there was no significant difference (P =0.542).Five adverse reactions including epigastric discomfort,nausea,diarrhea,taste disorder and liver injury were recorded during the treatment period.The incidence of adverse reactions such as epigastric discomfort and diarrhea in Saccharomyces boulardii group was significantly lower than that in standard triple therapy group [13.33％ (8/60)vs.43.33％(26/60),3.33％(2/60) vs.26.67％(16/60)],and there was significant difference (P ＜ 0.05).Conclusion Saccharomyces boulardii as an adjuvant to triple therapy can not improve Helicobacter pylori eradication rate,but can decrease the incidence of adverse reactions during the treatment period and improve the complicance of Helicobacter pylori eradication treatment.

To study the protective effect of Danqi Piantan capsule ( DPC) and its antelope horn substitution (DPCAS) on the cerebral ischemia, in order to preliminary study the possibility of replacing antelope horn with artificial bezoar. In this study, the left middle cerebral artery occlusion (MCAO) was adopted. Totally 150 SD rats were randomly divided into 5 groups: the sham operation group, the model group, the Danqi Piantan capsule (DPC) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn (DPCRA) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn and with double artificial bezoar (DPCDB) group (0.246 g x kg(-1) x d(-1)). The MCAO model was prepared 1 h later after the administration on the 5th day. At 24 h after the operation, the inner canthus blood was collected to determine the serum superoxide dismutase (SOD) activity and the endothelin (ET) content. At 72 h after the operation, the cerebral infarct size and the cerebral index were determined by TTC-staining. The fluorescent quantitative PCR method was used to detect brain Bcl-2, Caspase-3, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions. The mmunohistochemical method was used to detect ICAM-1, IL-1β, TNF-α, IL-6 expressions in ischemic penumbra. According to the results, compared with the model group, DPCDB and DPC groups showed almost consistent results, indicating both of the two group can significantly improved cerebral infarction index and cerebral index (P < 0.05), increase the serum SOD activity (P < 0.05), decrease the serum ET level and Caspase-3 expression, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions in brain tissues (P < 0.05) and expressions of ICAM-1, IL-1,6, TNF-α, IL-6 positive cells in ischemic penumbra (P < 0.05) and increase the Bcl-2 expression (P < 0.05). The DPCRA group showed much lower impacts on indexes than DPCDB and DPC groups. This suggests that DPCDB and DPC reveal similar efficacies and antelope horn in Danqi Piantan capsule can be substitutes by artificial bezoar.
