Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.

Objective To investigate the effect of rivaroxaban on prevention from deep venous thrombosis after hip replacement surgery .Methods 80 patients with lower limb parallel arthroplasty were randomly divided into observation group and control group from January 2014 to January 2015.40 cases in each group.Control group was given aspirin treatment, observation group was given rivaroxaban treatment, indicators changes were followed up and recorded.Results PT, APTT values of observation group one week after treatment were (35.79 ±2.16),(15.84 ±2.11) s, which were better than control group (45.64 ±2.12),(18.72 ±2.02) s (P<0.05).TT, D-dimer of observation group(13.48 ±2.10)s,(2.34 ±0.33)g/L after a week were better,than control group (16.38 ±1.79)s, (1.42 ±0.21)g/L (P<0.05) respectively.Conclusion Effect of rivaroxaban in prevent deep venous thrombosis after hip replacement surgery is exact without obvious adverses reaction, it is worthy of further research and application.

Objective To understand the clinical profiles of arthritis after human parvovirus B19(B19) infection.Methods Four cases were described and the clinical and laboratory characteristics were analyzed. Results The median onset age of the 4 patients(2 females and 2 males)was 34 years old.Typical clinical manifestations included joint symptoms,flu-like malaise and erythematous rash.Anti-Bl9 IgM antibodies were all positive in 4 patients.B19 DNA was detected in blood samples of 3.Other types of arthritis were excluded. No relapses were noticed after followed-up of 1～3 years.Conclusion The Anti-B19 lgM and B19 DNA should be detected in patients suffer from arthritis with unknown origin.

By analysis on existing problems of the classification, the suggestions were put forward to provide a reference for improving the classification of medical devices.

Objective To investigate the value of ultrasonography in evaluating the femoral artery thrombosis in rabbit. Methods Thrombosis was induced by external application with 10% ferric chloride and transient femoral artery-occlusion with bulldog clamp in twenty New-Zealand rabbits. The thrombosis was monitored by both Doppler flowmeter and ultrasonography. The histopathological result was used as the golden standard. The consistency of the above two results with the golden standard was analyzed. Results Thirty-two femoral arteries thrombosis were produced successfully. There was high consistency between the results of ultrasonic evaluation and histopathological examination (Kappa = 0. 720, P ＜ 0. 001 ), and moderate consistency between the results of Doppler flowmeter evaluation and histopathological examination (Kappa = 0. 546, P ＜0. 001 ). Within the thirty-two femoral arteries thrombosis, there were nineteen arteries with occlusive thrombus examined by histopathological means. Both the results of Doppler flowmeter and ultrasonography were highly consistent with the results of histopathological examination (Kappa = 0. 800 and 0.798 respectively, P ＜ 0. 001 ). Conclusions There is high consistency between the results of ultrasonic evaluation and histopathological examination for the common femoral artery thrombosis in rabbit.In the non-occlusive thrombus diagnosing,ultrasonography is better than Doppler flowmeter.

Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

Objective To investigate the clinical curative result of the new method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation.Methods From March 2006 to October 2012,21 patients (15 male,6 female) with chronic peroneal tendon subluxation via a novel method of postermedial deepen of the fibular groove.In this group:Ⅰ grade 5 cases;Ⅱ grade 9 cases;Ⅲ grade 5 cases;Ⅳ grade 2 cases.All patients were followed up for at least 24 months.The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score and visual analogue score (VAS) were used to evaluate the clinical outcomes.Operation time,time to heal and complications were also recorded.Results The average operation time was 50 minutes (30-70 minutes).The blood loss was 30-60 ml,average 40 ml.All incisions healed after operation,no case of incision infection,skin necrosis and sural nerve,vascular injuryed.Mean AOFAS score was significantly increased from (55.2±7.1) preoperative to (93.6±5.6) postoperative.15 patients with excellent,good for 1 cases.The excellent and good rate was 100％ (16/16).VAS score by an average of (5.3±2.1) points down to (1.2±1.1) points postperative.All the patients can wear normal shoes postoperative,waking with normal gait.No patients had peroneal tendon tenosynovitis,tendon adhesion,fracture of lateral malleolus and other serious complications,no dislocation recurrent,strength of the peroneal muscle returns to normal.Conclusion The novel method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation was safe and effective for ankle instability with a relatively short time.
