BACKGROUND:Periprosthetic femoral fracture is a severe complication after total hip arthroplasty. More than 85% belongs to Vancouver B2 and B3 fractures, and the operation is difficult. OBJECTIVE:To explore the clinical effect of Cable-Ready fast system and biotype long-stem prosthesis and its effect on the recovery of joint function in patients with Vancouver B2 and B3 type periprosthetic femoral fractures after total hip arthroplasty. METHODS: A total of 60 patients receiving total hip arthroplasty suffered from Vancouver B2 and B3 type periprosthetic femoral fractures in the Huanggang Central Hospital from September 2011 to September 2012. They were equaly divided into control and observation groups according to different fixation methods. Patients in the control group were treated by ordinary steel wire cerclage fixation combined with uncemented long-stem prosthesis; those in the observation group were treated by Cable-Ready fast system combined with fast uncemented long-stem prosthesis. RESULTS AND CONCLUSION:The average operation time, the time of hospitalization and fracture healing time were shorter in the observation group than in the control group. Moreover, the intraoperative blood loss was less in the observation group than in the control group. After 1 year of folow-up, Harris hip score was higher in the observation group compared with pre-treatment (t=3.174 9,P=0.002 6), and significantly higher than the control group (t=2.479 8,P=0.015 4). The excelent and good rate of Harris hip score was significantly higher in the observation group than in the control group (χ2=11.294 5,P=0.002 6). The total incidence of complications was significantly lower in the observation group than in the control group (χ2=8.139 7,P=0.04 2). These data indicate that Cable-Ready fast system combined with uncemented long-stem prosthesis in the treatment of Vancouver B2 and B3 periprosthetic femoral fractures after total hip arthroplasty has smal injury, less postoperative complications and better recovery of hip function after operation.

Objective To investigate the clinical features of divergence paralysis improve the diagnostic and therapeutic ability,and evaluate the effect of surgical and non-surgical treatment.Methods It was a retrospective case series study.11 cases with complete data,diagnosed and treated as divergence paralysis in Tianjin Eye Hospital from September 2014 to January 2016,were summarized.The observation items included general date,neurologica consultation,comprehensive eye examination,and the eye position and movement,deviation degree,binocular vision,AC / A,diplopia examination of pre-treatment and post-treatment.The patients were followed up from 3 months to 1.5 yeas,averaged 6.9 months.Results In our study,1 patient was MillerFisher syndrome,3 cases had a history of hypertension,and 1 case had the history of intaking sleeping pills for about 3 months.The rest of the patients denied the nervous system disease,cardiovascular disease and other medical history.All patients complained about uncrossed diplopia only at distance.All of the 11 patients had a sudden onset of their symptoms.Each patient was examined by same neurologist,meanwhile MRI or CT were performed.All the results showed normal.All patients had refractive error.The angle of esotropia for distance of 5 meters was from + 25 △ to + 55 △ and was from + 8 △ to + 40△ for near(33 cm)before treatment while changed into-4△ ～ + 12△ for distance (5m) and to-8△ ～ +8△ for near (33 cm) after treatment.The ratio of AC / A ranged from 1.3 to 4.0,with an average of 2.6.Conclusion The clinical characteristics of divergence paralysis are a greater angle of esotropia and ipsilateral diplopia.Lateral rectns resection and non-surgical treatment have better effects on the improvement of diplopia and esotropia.

OBJECTIVETo investigate the effect of plasma neuropeptide Y (NPY), neurotensin (NT) and their relationships on the diurnal rhythm of BP and target organ damage for essential hypertension.

METHODSAmbulatory BP monitoring (ABPM) for 24 hours was performed in ninety patients with essential hypertension and thirty healthy subjects. The patients were divided into two groups: 55 dippers and 35 non-dippers according to the ABPM results. Plasma NPY and NT levels in subjects were measured at 8:00, 16:00 and 2:00 o'clock by using radioimmunoassay method. Target organ functions were measured.

RESULTSThe plasma NPY level was higher and NT was lower in patients with hypertension those in normal controls (P < 0.001). Compared with dippers, non-dippers had a higher NPY and a lower NT plasma levels, especially appearing at 2:00 o'clock. The patients with left ventricular hypertrophy, stroke or kidney damage had a higher NPY and a lower NT levels compares with those without target organ damage.

CONCLUSIONThe changes in plasma NPY and NT may contribute to disturbance of the diurnal rhythm of blood pressure in patients with essential hypertension, especially in those with target organ damages, which may serve as a pathophysiologic mechanism for target organ damages in hypertension.
