Objective To study the effect of quercetin on proliferation and expression of P38MAPK and HMGB1 protein in neonatal rat cardiac fibroblasts induced by TNF-α.Methods Purified cardiac fibroblasts were obtained by trypsin digestion and differential adherence method.The proliferation of cardiac fibroblasts was detected by MTT assay.The expression of P38MAPK and HMGB1 protein was detected by Western blot.Results Quercetin had no effect on the proliferation of cardiac fibroblasts in the basal state but inhibited the proliferation of cardiac fibroblasts induced by TNF-α,and the A value of each group was increased with the increase of quereetin concentration(P<0.05).The exspression of P38MAPK、HMGB1 were decresed with the icrease of quercetin.Conclusion Quercetin may inhibit the proliferation of cardiac fibroblasts induced by TNF-α.The mechanism may be inhibit the expression of HMGB1 through P38MAPK signaling pathway.

OBJECTIVETo investigate the long-term clinical effects of modified double Endobutton technique for the treatment of acromioclavicular joint dislocations of Tossy type III.
METHODSA retrospective study was done in 42 patients with acromioclavicular joint dislocations of Tossy type III treated with modified double Endobutton technique from December 2008 to December 2010. There were 24 males and 18 females, ranging in age from 21 to 56 years old (averaged, 32.5 years old). All the patients were treated with open reduction, coracoclavicular ligament reconstruction using double Endobutton technique, and repair of acromioclavicular ligament. The Karlsson system was used to evaluate therapeutic effects. The distance from coracoid to clavicle was measured to evaluate reduction loss.
RESULTSAll the patients were followed up, and the duration ranged from 2.0 to 3.2 years (averaged,2.4 years). According to Karlsson system, 32 patients got an A degree and 10 patients got a B degree at three months post-operatively; 26 patients got an A degree and 16 patients got a B degree at the latest follow-up; 6 patients got an A degree at 3 months after operation lowered to B degree at the latest follow-up. The coracoid-clavicle distance increased from (26.91 +/- 0.91) mm at 3 months after operation to (27.41 +/- 1.10) mm at the latest follow-up. Te patients treated with over-reduction during operation or with heavy physical labour work after operation had obvious widened coracoid-clavicle distance. Bone absorption was found around the plate in most cases, mainly in the clavicular side.
CONCLUSIONTreatment for acromioclavicular joint dislocations of Tossy type III with modified double Endobutton technique has satisfactory early clinical results. But with time passing, loss of reduction and bone absorption around the plate could be observed, and clinical outcomes of some cases downgrade during the long-term follow-up.

Clinical practice teaching is the deepening and continuity of school education , which is an important part of medical education. This paper aims to analyze the current situation and problems as to the teaching management during clinical training of full-time clinical major students, and put forward the corresponding countermeasures . The clinical practice teaching management and the clinical intern training quality can be significantly improved by establishing normative practice teaching management sys-tem, innovating teaching management mechanism, and correct treatment of the contradiction between clin-ical practice, employment and taking part in the entrance exams for postgraduate schools.

Objective To investigate the efficacy of the combination of improved intramedullary VSD drainage and contained antibiotics bone graft to treat chronic tubular bones osteomyelitis.Methods From March,2011 to December,2013,our department have total of 40 patients with chronic tubular bones osteomyelitis.Twenty cases (group A) treat with one-stage osteomyelitis debridement cortical bone slotted,contained antibiotic bone and autologous bone implants and wound repair.Twenty cases (group B) treat with improved intramedullary VSD drainage 3-5 days temporarily after osteomyelitis debridement cortical bone slotted,then contained antibiotic bone and autologous bone implants and wound repair.A retrospective comparison of two groups of an average residence time of wound drainage postoperative,bone bed bacterial culture positive rate,average healing time,the average time of hospital stay,the average bone healing time,and recurrence rate of osteomyelitis.Statistical analysis with T test was used for above independent parametric.Results The two groups were followed-up for 6-24 months,independent samples t-test was used for two groups in the wound healing time,bone healing time,the drainage tube removal time and the length of hospital stay,in group A bone bed bacteria culture positive rate was 40%,group B was 5%,group A infection relapse has 2 cases,1 case was debridement cured,1 case was amputation,and the recurrence rate of 10%.Group B without infection recurrence,and the recurrence rate of 0% ; The healing time and hospital stay of intramedullary drainage surgery patients (18.05 ± 2.74 d and 22.65 ± 2.80 d,respectively,in group B) was significantly less than one-stage surgery patients (24.10 ± 8.20 d and 28.10 ± 9.35 d,respectively,in group A),but the bone healing time and the drainage tube removal tine of two groups.There was no significant difference (P > 0.05).Conclusion Contained antibiotic bone and autologous bone implants with wound healing therapy after osteomyelitis debridement cortical bone slotted with improvement VSD intramedullary drainage to treat patient with tubular bones osteomyelitis was more effective,it worthy of clinical spread.

Objective: To discuss the entry point of clinical pharmacists for providing pharmaceutical care in clinics. Methods:Clinical pharmacists participated in making drug treatment regimen for one child with nephritic type NS combined with hypertension,and provide pharmaceutical care and medical education for the patient. Results: According to the situation of the patient, the treatment regimen was made out, evaluated and adjusted, and ADR was dealt with in time, therefore, the individualized treatment showed obvious effect, and the child was discharged with an improved condition. Conclusion: Clinical pharmacists can participate in clinical treatment with pharmaceutical professional knowledge to ensure safer and more effective drug use in child patients.

AIM:To investigate the value of pattern visual evoked potential (PVEP) and flash electroretinogram (FERG) in early diagnosis and prevention of diabetic retinopathy (DR), analyzing the correlation of early stage DR with PVEP and FERG.
METHODS: Sixty patients, 30 males and 30 females, participated in observation group. Their average age was 19. 42 ± 7. 78years. The duration of DM was < 5a. Best corrected visual acuity was 5. 0. Fasting blood glucose was 7. 8± 3. 6mmol/ L. There were 60 subjects, 30 males and 30 females, in control group. Their average age was 17. 2 ± 6. 52years. Best corrected visual acuity was 5. 0. Every participator was tested with PVEP and FERG according to ISCVE standard. The amplitude of PVEP and P100 latency were recorded. And the b-wave latency, b-wave amplitude, a - wave latency, a - wave amplitude were showed down.
RESULTS: In observation group, P100 amplitude decreased and P100 latency increased, compared to those of control group ( P< 0. 01); b - wave latency, b -wave amplitude, a - wave latency, a - wave amplitude were different from those in control group(P<0. 01); the fasting blood glucose kept stable; P100 amplitude, b -wave amplitude and a-wave amplitude were not related to the DM duration; P100 latency, a-wave latency and b-wave latency were related to the DM duration.
CONCLUSION: PVEP are sensitive to optic neuron damage; FERG is desirable to detect the lesion of Müller cells and bipolar cells. P100 amplitude by PVEP, b-wave amplitude by FERG may be the most sensitive parameter for DR at early stage.
