Objective: To explore the preventive efficacy of local injection of hyaluronidase and topical administration of Hirudoid cream against skin damage caused by vinorelbine extravasation in rats. Methods: Vinorelbine was iv infused into the hinder limbs of SD rats to establish the extravasation model. The 48 rats were randomly divided into 6 groups. The model group received no treatment. The other five groups were given local injection of hyaluronidase, topical administration of Hirudoid cream, local injection of hyaluronidase plus topical administration of Hirudoid cream, local injection of normal saline (NS), or topical administration of normal saline, respectively. The lesion area and the healing time were observed and recorded on d 1, d 4, d 8, d 12, d 18, d 24, and d 30. Results: The lesions were cured by local injection of hyaluronidase on d 30. The lesion area were significantly reduced in hyaluronidase group compared with that in topical Hirudoid cream group, combined therapy group, local NS injection group, topical NS administration group, and the model group on d 1, d 4, d 8, d 12, d 18 and d 24 (P < 0.05). The healing time was significantly shorter in hyaluronidase group than that in other 5 groups [(21.9 ± 3.0) d vs (28.8 ± 3.5) d, (28.0 ± 2.9) d, (28.6 ± 4.1) d, (29.8 ± 2.6) d, and (30. 6 ± 3.0) d, P < 0.01]. Conclusion: Local injection of hyaluronidase is effective for skin damage caused by vinorelbine extravasation, but topical administration of Hirudoid cream is ineffective and combined therapy can not further improve the efficacy of hyaluronidase monotherapy.

Adenocarcinoma of exocrine pancreas is a highly malignant tumor with extremely low resectability.Radiotherapy,by inducing necrosis and apoptosis of tumor cells through irradiation effects on cellular DNA,in combination with chemotherapy,has made great contribution to multimodal treatment of this malignancy.The development of radiation therapy for pancreatic carcinoma in recent years was reviewed in neoadjuvant and adjuvant settings,and for locally advanced disease.Further evidence is required to show the impact of radiochemotherapy in the treatment of unresectable disease.

Objective: To study the effect of early rehabilitation on motor function of upper and lower extremities and activities of daily living(ADL) in patients with hemiplegia after stroke; and to observe whether motor function recovery of upper and lower extremities is different. Method: 96 patients were randomly divided into two groups, rehabilitation group (48 cases) and control group(48 cases). Prospective method was used in this study. Patients in the rehabilitation group were given clinical treatment and regular rehabilitation training, while those in control group were given clinical treatment and unguided self- training. The evaluation was done in pre- treatment and post- treatment(6- 8 weeks) respectively.Motor function was assessed in Fugl-Meyer assessment(FMA), ADL assessed in Barthel Index. Result: The motor scores (measured by FMA) and ADL scores (measured by Barthel index) in the two groups were improved after 6-8 weeks treatment, but there was a significant difference between the two groups, the scores in the rehabilitation group were obviously superior to those in the control group (P ＜ 0.01 ). The mean of the Fugl-Meyer Scale (transferred to percentage of maximal motor scores) of the lower extremities was higher than that of the upper extremities pre-and post-treatment (P＜0.01). However, the improvement degree of FMA scores between upper and lower extremity had no statistical difference (P＞0.05). Conclusion:Early rehabilitation training of the patients with stroke hemiplegia may obviously improve motor function of the limbs and raise ADL scores. However, the degree of improvement in upper and lower extremity is similar in the first two months after early training.

Objective To evaluate the expression of Survivin,PTEN in tongue squamous cell carcinoma (TSCC) and the correlation with vascular endothelial growth factor (VEGF) and its clinical significance.Methods The expression of Survivin,PTEN and VEGF of 72 TSCC samples and 15 normal tongue mucosa (NTM) samples were detected by immunohistochemical method.Results The positive expression rate of Survivin,PTEN and VEGF in TSCC were 66.7％(48/72),61.1％(44/72),70.8％(51/72)respectively,while the positive expression rate in NTM were 0,100.0％ (15/15),0.There were statistical significance between the rate in TSCC and NTM respectively (P ＜0.01 ).The expression of Survivin and VEGF in TSCC were positively correlated with TNM stage,histological grade and lymph node metastasis (P＜ 0.05 or ＜ 0.01 ),while the expression of PTEN had negative correlation with them (P＜ 0.05 or ＜ 0.01 ).The expression of Survivin was positively correlated with VEGF expression in TSCC (r=0.6482,P＜0.01),while the expression of PTEN was negatively correleted with VEGF expression (r =-0.4027,P ＜0.01).Conclusions The expression of Survivin and PTEN in TSCC are associated with tumor occurrence and development closely,and are both significantly correlated with VEGF.Joint detection of Survivin,PTEN and VEGF have important reference value in clinical diagnosis,metastasis and prognosis of TSCC.

Objective To analyze the causative of damaged bioprosthetic valves implanted in 41 patients (with total 47 valves) over one year. Methods From June 1993 to June 2004,re-replacement of valves was performed in 41 patients with dysfunctional bioprosthetic valves. The interval between the two operations was 1～16 years [mean (9.7?4.1) years]. The 47 dysfunctional bioprosthetic valves were carefully observed and pathologically examined. Results Of the 47 valves, no valve frame was damaged; tear or perforation existed in 42 valves (89.3%); calcification was found in 35 valves (74.5%), with fibrosis; excrescence and thrombus coexisted in 2. Heavily damaged ones were sent for pathological examination, and infiltration of abundant phagocytes and monocytes was found. Conclusion Early damages were mainly tear or rupture, while late damages were compound outcomes of multiple damaging factors such as calcification, rupture, and tear.

In order to understand the natural evalution of the motor function and the activities of daily living(ADL) in post stroke patients,and to provide scientific basis for the early treatment and rehabilitation training of the stroke patients,the motor function and ADL of 150 stroke patients without systematic rehabilitation training were evaluated at 5-6 week and 6 month of post stroke,respectively.The results showed that most patients had functional improvements.The functional recovery of upper limbs and especially hands was worse than that of lower limbs.The average ADL scores increased from 59.80 to 69.54,but the improvements were unsatisfactory.The results suggested that it is necessary to carry on the early rehabilitation training for the stroke patients fo that the patients motor function and ADL could improve more quickly and better to greater degree.

Objective To investigate the clinical performance of fiber post restorations in elderly patients with residual root and crown and to analyze the factors affecting the clinical success rate.Methods A total of 66 elderly patients requiring post restoration were selected.They were randomly divided into two groups:the observation group (n=33,restored with fiber post-resin cores) and the control group (n=33,restored with cast metal post-cores).All patients were rechecked 1 year and 2years after the restoration.The clinical efficacy and the failure types were recorded.The differences in clinical performance between the 2 groups were compared by using Fisher's exact test.Results The differences in the gingival index and periodontal index in the 2 groups between the experimental teeth and the control teeth were zero.There were no significant differences in dental morphology,root canal treatment failure,tooth color matching and marginal coloration between the 2 groups (all P＞0.05).1 case with post debonding and 1 case with fiber post fracture were found in the observation group and 1 case with marginal coloration was found in control group.There was no significant difference in clinical success rate between the 2 groups (93.94％ vs.96.97％,P＞0.05).Conclusions The clinical success rate in fiber post-resin core restoration is the same as in cast metal post-cores restoration in elderly patients.

Objective:A study was conducted to investigate the effect of Prunella vulgaris sulfated polysaccharide (PVSP) on the expression of angiogenic growth factors (bFGF, VEGF, and IL-8) and angiogenesis in hepatocellular carcinoma. Methods:ELISA as-say was used to observe the effects of PVSP and the negative control drug Lentinan (LNT, non-sulfate radical drug) on secretions of the angiogenic growth factors, namely, bFGF, VEGF, and IL-8, in HepG2 cells in vitro. In an in vivo experiment, the microvessel density in hepatocellular carcinoma tissue sections treated with PVSP and LNT was calculated, analyzed, and compared with the microvessel den-sity in the phosphate-buffered saline (PBS) control. Results:Compared with the PBS control group, PVSP at 200μg/mL inhibited bF-GF secretion (P<0.01), whereas LNT failed to affect bFGF secretion. Neither PVSP nor LNT affected the secretions of VEGF and IL-8. In vivo results showed that PVSP at 200 mg/kg reduced the microvessel density in tumor tissue sections (P=0.03), whereas LNT at 10 mg/kg failed to affect microvessel density. Conclusion:Inhibition of bFGF secretion is a probable mechanism underlying the preven-tive effect of PVSP on hepatocellular carcinoma angiogenesis.

BACKGROUND:Compared with bone marrow transplantation, peripheral blood stem cel transplantation has its own advantages, including rich resources of stem cel s from the peripheral blood, convenient and easy col ection, without anesthesia, smal trauma, easily accepted, high safety, and easy to restore the patient’s hematopoietic system.
OBJECTIVE:To observe the function and safety of autologous peripheral blood mononuclear cel s in the treatment of patients with decompensated cirrhosis.
METHODS:Four patients with decompensated liver cirrhosis were selected from November 2010 to July 2011 in the First Affiliated Hospital of Dalian Medical University, aged 31-67 (averagely 44 years). Among them, three cases had hepatitis B, and another one had autoimmune liver disease. Peripheral blood stem cel s were col ected after being mobilized by granulocyte colony stimulating factor. Then, autologous peripheral blood stem cel s were transplanted via a hepatic artery catheter.
RESULTS AND CONCLUSION:There were no adverse reactions such as fever, bleeding and nausea after peripheral blood stem cel col ection and hepatic artery transplantation. Symptoms such as fatigue, poor appetite and abdominal distension gradual y improved at 1, 3 and 6 months after transplantation. Liver function and liver fibrosis indexes were improved to some extent after transplantation.

According to the structure-activity relationships (SARs) of modafinil, a therapeutic drug of hypnolepsy, we designed and synthesized two series of compounds 2-[(diphenylmethane)sulfinyl] acetamides and 2-[(diphenylmethyl)thio] acetamides, and measured their biological activities. The target compounds (6a-6o) were synthesized beginning with diphenyl carbinol by substitution, oxidation, acylation and so on. Their structures were confirmed by ESI-MS, 1H NMR and elemental analysis. The central stimulatory effects of the target compounds were determined by the independent activity assay on mice. Compounds 6c, 6f and 6n have considerable activities, while the central stimulative effect of 6h is slightly better than the positive control modafinil.
