OBJECTIVETo investigate the clinical effects of close reduction and minimally invasive percutaneous plate osteosynthesis in treating proximal humerus fractures in the aged.

METHODSFrom February 2012 to December 2013,39 patients with proximal humerus fractures were treated with minimally invasive percutaneous plate osteosynthesis (MIPPO group, 21 cases) and open reduction internal fixation (ORIF group, 18 cases). Including 17 males and 22 females in the study, and aged from 67 to 88 years old with an average of (71.8 ± 5.2) years old. In MIPPO group, there were 11 males and 10 females with an average age of (70.0 ± 5.3) years old;and in ORIF group, there were 10 males and 8 females with an average age of (72.0 ± 4.2) years old. Operation time, blood loss during operation, fracture healing time and postoperative complications were recorded. The functions of the shoulder joints were assessed according to Constant-Murley score at final follow-up.

RESULTSAll the patients were followed up from 11 to 27 months with an average of 18.1 months. The mean blood loss of the MIPPO group was (176.0 ± 57.4) ml,while the ORIF group was (356.0 ± 66.9) ml (t = 7.22,P = 0.01). The operation time of the MIPPO group was (47.4 ± 14.9) min, while the ORIF group was (92.7 ± 15.8) min (t = 0.79, P = 0.03). Fracture healing time in the MIPPO group and ORIF group was (17.6 ± 5.8), ( 21.7 ± 4.9) weeks, respectively (P < 0.05). The mean Constant-Murley score at final follow-up was 89.7 ± 14.5 in MIPPO group, and 81.8 ± 13.2 in ORIF group (P < 0.05).

CONCLUSIONMIPPO has advantages of little trauma, less blood loss, rapid recovery, less vascular damage and so on and can effectively treat the proximal humerus fracture in the aged.

Objective To study the changes of portal vein pressure before and after interventional embolization with α-cyanoacrylate alkyl and their clinical significance. Methods Thirty five patients with esophageal-gastric variceal bleeding were included. Esophageal-gastric fundal varices were embolized with e-cyanoacrylate alkyl in 35 patients, and 10 of them were treated with combination of partial splenic emblization. Portal pressure was measured directly before and after interventional embolization. The patients were followed up for 3-18 months. The changes of the liver functions and complications after the embolization were observed. Results All bleeding were controlled successfully. The main portal pressure in those who received variceal embolization only increased significantly from (32.54±5.23) cm H2O (1 cm H2O=0. 098 kPa) to (37.45±5. 11) cm H2O; superior mesenteric vein pressure increased from (31.46±4.35) cmH2O to (34.33±4.68)cm H2O; and the level of serum albumin raised from (30.45±5.78) g/L to (34.57±6.84) g/L 3 weeks after embolization. Whereas the main portal pressure in those who received both variceal and partial splenic embolizations, decreased significantly from (32. 68±4. 89) cm H2O to (28. 70±4. 58) cm H2O; superior mesenteric vein pressure decreased from (31.46±4.35) cm H2O to (28.03±4.12) cm H2O; and splenic vein pressure decreased from (32.89±4.79) cm H2O to (28.81±5. 12) cm H2O.Conclusions Esophageal-gastric variceal embolization is effective for varieeal bleeding. The increase of main portal pressure after embolization may be benefit for liver function, while the rise of superior mesenteric vein pressure may increase the risk of portal hypertensive gastrointestinal re-bleeding.Esophageal-gastric variceal embolization combined with partial splenic embolization may reduce the incidence of portal hypertension and gastrointestinal re-bleeding, but will increase the risk of ascites.

Objective To investigate safety and efficiency of anti-coagulation therapy in patients with high-risk of bleeding and multiple organ dysfunction syndrome (MODS) during continuous veno-venous hemofiltration (CVVH). Meth-ods Forty patients with high-risk bleeding MODS during CVVH in our hospital were divided into heparin-free group (A group) and low-dose heparin group (B group). Blood coagulation function, platelets counts, blood urea nitrogen, serum creati-nine, PaO2/FIO2 and Apache Ⅱ scores in two groups were tracked before treatment and 24 h, 48 h after treatment. Filter lifespan, median ventilation time, ICU admission time and bleeding complications were observed. Results (1)There was significant difference in levels of blood urea nitrogen, serum creatinine, PaO2/FIO2 and ApacheⅡscores at 24 h, 48 h after treatment between in low-dose heparin group and those in heparin-free group (P＜0.05). (2)Levels of activated partial thromboplastin time(APTT), thrombin time (TT) were prolonged. Platelets count were significantly lower at 24 h after treat-ment than that before treatment in low-dose heparin group. Levels of APTT, TT and platelets count had no changes with pro-longed time of CVVH therapy.(3)Average ventilation time, ICU admission time were obviously shorter in low-dose heparin group than that in heparin-free group. Filter lifespan was significant longer in low-dose heparin group than that in heparin-free group, (P＜0.05).(4)Bleeding in skin and mucosa was observed in 1 case in low-dose heparin group without other se-vere bleeding complications. Conclusion The results of monocentric study show that low dose of heparin ensure smooth op-eration of CVVH in patients with MODS and high-risk bleeding. The clinical application is safe and efficient.
