Objective To analyse the treatment results of proximal humerus fracture in over sixty-years-old patients. Methods From January 1999 to January 2003, 32 cases suffered from fractures of the proximal humerus were studied, which involved 13 males (mean age 73.2 years, range 60-88 years), and 19 females (mean age 75.5 years, range 60-94 years). There were 22 cases (65.7%) with two-part fractures, among them, 68.1% was surgical neck fracture. 3 cases with two-part and 1 with three-part fracture were treated conservatively because of either their poor health condition or their refusal to operation. The other 28 patients were operated. According to the Neer classification, through the statistic and analysis for the method and outcome, all the cases were evaluated in term of the American UCLA scale system. Results 25 of the 28 operated patients were available at the final follow-up, the mean period was 1.5 years with a range of 1 to 3 years. All the fractures had united. 5 patients with healing time more than 3 months were those fractures classified as three or four-part, which needed the tension-band fixation. All the patients complained with joint stiffness in different degree, 6 of the patients with three or four-part remained with sustaining shoulder contracture. According to the UCLA, the good-excellent rate was 81.2% in the two-part fractures, and only 33.3% in the three or four-part fractures. Conclusion The treatment methods of proximal humerus fracture in aged patients should be selected according to individual condition. The tension band fixation is a good choice for those who can't accept the joint replacement, though the outcome after the four-part fractures fixation is less satisfactory. Joint contracture and humeral head necrosis may be the common complications among the patients rated as three or four-part fractures. After operation, early and complete rehabilitation are closely related to the treatment results.

Objective: To explore influence of nursing health education on morning blood pressure surge (MBPS) fluctuations in aged patients with hypertension.Methods: A total of 100 outpatients and inpatients with non-dipper hypertension, who haven't been treated, were selected from Apr 2011 to Sep 2015.According to random number table method, patients were randomly and equally divided into routine treatment group and health education group (received nursing health education based on routine treatment group), both groups were treated for four weeks.MBPS, trough/peak(T/P) ratio and smoothness index (SI) were measured and compared between two groups after treatment.Results: Compared with routine treatment group after four-week treatment, there were significant reductions in systolic blood pressure (SBP) morning surge[(46.95±5.17) mmHg vs.(42.21±5.19) mmHg]and diastolic blood pressure (DBP) morning surge[(16.31±3.23) mmHg vs.(14.21±3.58) mmHg], and significant rise in SBP T/P[(59.22±6.65)% vs.(70.11±6.41)%], DBP T/P[(50.91±5.04)% vs.(56.97±5.12)%], SBP SI[(1.19±0.13) vs.(1.42±0.12)]and DBP SI[(1.11±0.09) vs.(1.29±0.08)]in health education group, P<0.05 all.Conclusion: Health education can effectively improve blood pressure fluctuations and may likely improve prognosis in patients with non-dipper hypertension, which is worth extending.

Objective To investigate the treatment effect of the proximal humeral internal locking system (PHIL()S) on the elderly patients with displaced proximal humeral fractures.MethodsFrom Feb 2004 to Mar 2007, 36 patients (mean age: 72.2 years) with proximal humeral fractures were treated with PHILOS plate fixation which included 14 cases with 2-part, 17 cases with three-part and 5 cases with four-part fractures according to Neer classification.Operation time,intraoperative blood loss, blood transfusion, perioperative complications and function evaluation of the operated shoulder joint were calculated with 14.5 months follow-up at average.Results The average operation time and blood loss were (61.5± 11.6) min and ( 165.2±91.2) ml, respectively. 1 case with accidents of blood vessel and 1 case with pneumonia were found without neurovascular injuries. All fractures were radiographically healed in an average of 3-5 months.No necrosis of humeral head appeared and 30 (83.3％) cases were excellent or good according to Neer scoring system. Two part fracture and early operation ( within 3 days after operation) might improve the postoperative function of shoulder joint, but the patient's age, gender and ASA score were not statistically with Neer score.Conclusions PHILOS plate fixation is a suitable procedure for displaced proximal humeral fractures via stable fixation and early rehabilitation, especially for elderly patients combined with osteoporosis.

Background: Sorafenib and sunitinib are widely used as first-line targeted therapy for metastatic renal cell carcinoma (mRCC) in China. This study aimed to compare the efficacy, safety, and quality of life (QoL) in Chinese mRCC patients treated with sorafenib and sunitinib as first-line therapy. Methods: Clinical data of patients with mRCC who received sorafenib (400 mg twice daily; 4 weeks) or sunitinib (50 mg twice daily; on a schedule of 4 weeks on treatment followed by 2 weeks off) were retrieved. Primary outcomes were overall survival (OS), progression-free survival (PFS), adverse events (AEs), and QoL (SF-36 scores), and secondary outcomes were associations of clinical characteristics with QoL. Results: Medical records of 184 patients (110 in the sorafenib group and 74 in the sunitinib group) were reviewed. PFS and OS were comparable between the sorafenib and sunitinib groups (bothP > 0.05). The occurrence rates of leukocytopenia, thrombocytopenia, and hypothyroidism were higher in the sunitinib group (36.5％ vs. 10.9％, P < 0.001; 40.5％ vs. 10.9％,P < 0.001; 17.6％ vs. 3.6％,P= 0.001), and that of diarrhea was higher in the sorafenib group (62.7％ vs. 35.2％,P < 0.001). There was no significant difference in SF-36 scores between the two groups. Multivariate analysis indicated that role-physical and bodily pain scores were associated with the occurrence rate of grade 3 or 4 AEs (P= 0.017 and 0.005). Conclusions: Sorafenib has comparable efficacy and lower toxicity profile than sunitinib as first-line therapy for mRCC. Both agents showed no significant impact on QoL of patients.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.
