Objective To use a simple bedside technique to verify the pathophysiological mechanism of pulmonary hypertension (PH) in different races. Method The Valsalva maneuver (VM) was performed in patients referred to a specialty PH clinic. The blood pressure response of patients to VM was in different fashions. The blood pressure (BP) was measured by using cuff and stethoscope. When the cuff was inflated to 15 mmHg above the systolic pressure, sound could be heard by auscultation during VM and when the cuff was deflated the sound disappeared over 3 heart beats which was considered as abnormal BP response, and less than 3 heart beats defined as normal BP response. The right heart catheterization in patients with PH as a part of the standard evaluation. Results This study included 84 patients with a mean age of (63 ± 16) years. Those with abnormal BP response to VM had higher pulmonary artery wedge pressure (PAWP) [(22.5±6.6) vs. (11.9±4.3) mmHg, P ＜0.0001] and lower pulmonary vascular resistance [(5.8 ± 4.0) vs. (8.1 ± 4.6 ) WU, P = 0.01]. Blood pressure response to VM did not correlate with mean pulmonary artery (PA) pressure [(46.2 ± 9.9) vs. (43.4 ±10.4) mmHg, P =0.20] or cardiac index (both 2.4 ± 0.6 L/min/m2). The abnormal BP response to VM had high sensitivity (89.4%), specificity (86.1%) and accuracy (86.9%) for determining PAWP＞ 15 mmHg.Conclusions BP response to Valsalva maneuver provides important information about left heart filling pressures in patients with PH.

ObjectiveTo investigate the independent risk factors of 30-day mortality of nontraumatic acute chest pain in emergency department so as to get non - traumatic acute chest pain risk score,MethodsThe clinical data of 532 patients with non - traumatic acute chest pain were reviewed.The independent risk factors of 30 - day mortality were identified after analysis of medical history,symptom and sign,laboratory findings by uuivariate analysis and logistic regression.Non- traumatic acute chest pain risk score was made as per the odds ratios of these risk factors. ResultsThe average age of the patients was (55.7 + 12.7 ) years,and 45 patients ( 8.4％ ) died after 30 days.In patients with non - traumatic acute chest pain,history of hypertension (OR:4.28; 95％ CI:1.59-11.55 ),prolonged chest pain (OR:1.1; 95％ CI:1.05-1.15),dyspnea (OR:6.61; 95％CI:2.40-18.10) and tachycardia (OR:1.02; 95％CI:1.00-1.04),high leucocyte count (OR:1.18; 95％CI:1.06-1.31) and D - Dimer ( OR:1.002; 95％ CI:1.001-1.002 ) predicted 30 - day mortality independently,whereas chest pain relieved by medicine (OR:0. 15; 95％ CI:0.04-0.65),high blood oxygen saturation (SaO2) (OR:0.89; 95％CI:0.83-0.98) and normal hematocrit (OR:0.92; 95％CI:0.86-0.99) were good markers to predict optimistic prognosis.Non - traumatic acute chest pain risk score was higher in 30 - day dead group than those in survival group significantly ( P ＜ 0.01 ),and mortality was significantly different between groups with various risk stratification (P ＜ 0. 01 ).Conclusions Clinical physician can predict 30 - day mortality and evaluate prognosis in patients with acute chest pain by using non - traumatic acute chest pain risk score quickly and effectively.

Objective To study the safety measures during perioperative period in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) , to minimize uvulopalatopharyngoplasty (UPPP) major complications. Methods The complications and other relative information of 1446 OSAHS patients treated with UPPP were analyzed. Complications of 1004 OSAHS patients adopted standardized management measures after 2004 and 442 OSAHS patients who performed UPPP before 2003 were compared. Results Among the 1446 cases of OSAHS surgery, there were 49 cases (3. 39% ) of difficult intubation; 8 cases (0.55%) intraoperative mild arrhythmia; 13 cases (0. 90%) of surgery dangerous situations after extubation; 19 cases (1. 31%) of intraoperative primary hemorrhage; 11 cases (0. 76%) of mild arrhythmia during the postoperative observation period; 21 cases (1.45%) of uncontrolled hypertension immediately after surgery; 32 cases of secondary hemorrhage a week after surgery. All complications were cured and no death occured. Compared with those operations before 2003, complications were significantly reduced with enforcement of standardized management of perioperative measures since 2004. The data had significant difference by χ2 test( P <0.05). Conclusions There are five key points during the periperative period of OSAHS surgery: preoperative examination, intubation, surgery, postoperative extubation, and postoperative care. Risk factors and complications could be prevented effectively in the above five important processes.

OBJECTIVETo observe the curative effect of porous tantalum rod and Gugutou Huaisiyu Capsule (GHC) for steroid-induced osteonecrosis of femoral head (SONFH).

METHODSA total 60 hips of 50 SONFH patients were randomly assigned to the treatment group and the control group according to grouping time, 25 in each group (30 hips). Patients in the control group were implanted with porous tantalum rod, while those in the treatment group additionally took GHC (5 pills each time, three time per day for 2 successive months; and then twice per day for 4 successive months). Then all patients were followed-up to observe Harris hip score. The curative effect and the femoral head survival time were assessed.

RESULTSA total of 49 patients (59 hips) were followed-up. The Harris hip score of the two groups at the final follow-up was significantly improved after treatment, with statistical difference when compared with before treatment (P < 0.01). Besides, it was higher in the treatment group than in the control group. The curative effect and the survival time were superior in the treatment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSPorous tantalum rod combined GHC got better effect in treating SONFH. It could significantly improve the function of affected hips and prolong the survival time of femoral head.
