Objective To investigate the protective effect and mechanism of recombinant hirudin on avulsed flap and to explore the application of recombinant hirudin in clinical treating avulsed flap.Methods 108 Sprague-Dawley rats were randomly divided into three groups:local injecting recombinant hirudin (group A),local injecting low molecular heparin (group B),and local injecting physiological saline (group C).The far ends were sutured after forming dorsal avulsed flap with local freeing.The levels of P-selectin and VEGF were detected,and the inflammatory cell aggregation and formation of microthrombus were observed in pathological section.On 14th postsurgery day the survival rate of flap was calculated.Results The content of P-selectin in group A was lower than that of groups B and C,with a statistical difference (P＜0.05).The content of VEFG in group A was higher than that of groups B and C,with a statistical difference (P＜0.05).On 14th postsurgery day,group A was higher than that in groups B (P＜0.05)and C (P＜0.01) in the survival rate of flap.Conclusions Locally injected recombinant hirudin can actively suppress the production of P-selectin,reduce accumulation of inflammatory cells,prevent information of microthrombus,improve ischemia and anoxia of avulsed flaps,decrease injuries of endotheliocyte,enhance the expression of VEGF,and stimulate hyperplasia of neogenesis capillaries that elevate survival rate of avulsed flaps.

Objective To explore the effect of Yatongning tincture root canal implantation on interleukin 8 ( IL-8 ) , cluster of differentiation 4 (CD4) and heat shock protein 70(HSP70) in in gingival crevicular fluid of patients with periodontitis.Methods 64 patients with periodontitis from December 2013 to September 2015 in stomatology department of Yuyao Second People’s Hospital were selected and according to the different treatment methods divided into treatment group and control group, 33 cases in treatment group, 31 cases in control group.Patients received root canal implantation in two groups, the treatment group received Yatongning tincture root canal implantation on the basis of control group.The clinical curative effect, incidence of pain, IL-8, CD4 and HSP70 levels were compared between two groups.Results The clinical curative effect of treatment group was 96.97%(32 cases), which was higher than 80.65% (31 cases) of control group (χ2 =4.373, P<0.05).The pain incidence of treatment group was 30.30%(10 cases), which was higher than 58.06% (18 cases) of control group (χ2 =5.006,P<0.05).After treatment, the IL -8 levels were higher and CD4, HSP70 levels were lower in two groups than those pre-treatment(P<0.05), compared with control group, the IL-8 levels were higher and CD4, HSP70 levels were lower in treatment group ( P<0.05 ) .Conclusion Yatongning tincture root canal implantation could enhance the clinical efficacy , relieve tooth tissue damage and improve the post-operative pain in patients.

Objctive To evaluate therapeutic effect of periocline ointment as an auxiliary treatment of adult serious chronic periodontitis. Methods 56 patients were divided into the test group and the control group in register sequence. Following initial therapy, patients in the test group were treated with PERIOCLINE into the periodontal pocket once a week for 4 weeks, while patients in the control group were treated with iodine glycerine. At the baseline level, the indexes of PLI,SBI,PD,AL were recorded and compared between the two groups on the 1st month, 3rd month and 6th month. Results All the indices of both groups were improved, compared with the baseline ( <0.05) . The results of the test group were better than those of the control group, and the differences were statistically significant (<0.05) . Conclusion Periocline ointment as an auxiliary treatment of adult serious chronic periodontitis is superior to compounded iodine glycerine in the amelioration of all the indices.

OBJECTIVE:To investigate the clinical efficacy and safety of recombinant human epidermal growth factor(rhEGF) combined with lipoic acid in the treatment of diabetic foot. METHODS:A total of 68 patients with diabetic foot were randomly divid-ed into observation group and control group with 34 cases in each group. Both groups were given conventional therapy and Lipolic acid injection 0.6 ml added into Sodium chloride injection 250 ml. ivgtt(protecting form light),qd;observation group was additionally giv-en rhEGF for external use 1 ml and vaseline on the wounds,gauze dressing,qd. Treatment course of 2 groups lasted for 7 d. Clinical efficacy,ulcer area,the expression of Bcl-2 and Bax were compared between 2 groups as well as the occurrence of ADR. RESULTS:The total effective rate of observation group(94.1%)was significantly higher than that of control group(67.6%),with statistical sig-nificance (P<0.05). Before treatment,there was no statistical significance in ulcer area,the levels of Bcl-2 and Bax between 2 groups(P>0.05). After treatment,ulcer area decreased significantly, the level of Bcl-2 increased significantly in 2 groups,while the level of Bax decreased significantly;the improvement of observation group was more significant than that of control group,with statis-tical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLU-SIONS:rhEGF combined with lipoic acid is effective for diabetic foot with good safety.

ObjectiveTo investigate the clinical efficacy of coiling-dragon warm needling atHuatuo jiaji points plus Chinese herbal fumigation in treating ankylosing spondylitis (AS).MethodEighty AS patients were randomly allocated to treatment and control groups, 40 cases each. The treatment group received coiling-dragon warm needling at Huatuo jiaji points plus Chinese herbal fumigation and the control group, oral administration of salicylazosulfapyridine (SASP). An investigation was made of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the patients’ overall assessment, the Bath Ankylosing Spondylitis Functional Index (BASFI), the total number of swollen joints, the Bath Ankylosing Spondylitis Measurement Index (BASMI) and laboratory inflammatory indices: erythrocyte sedimentation rate (ESR), platelet (PLT) and C reactive protein (CRP).ResultThere was a statistically significant difference in the marked efficacy rate between the two groups (P<0.05). Clinical indices: disease activity index and functional index and laboratory indices: ESR, PLT and CRP improved somewhat inboth groups of patients after treatment (P<0.05). After two courses of treatment, the therapeutic effect was better in the treatment group and there was a statistically significant difference compared with the control group (P<0.05).ConclusionCoiling-dragon warm needling at Huatuo jiaji points plus Chinese herbal fumigation can effectively relieve the clinical symptoms and reduce inflammatory reactions in the active stage in AS patients. It is an effective way to treat AS.

ObjectiveTo explore the value of CT virtual endoscopy in the treatment strategies in low rectal cancer surgery.MethodsFifty- seven cases of rectal cancer in Jining First Hospital were collected,preoperative rectum CT virtual endoscopy,detailed records of patients with rectal invasion and the circumstances surrounding lymph nodes were investigated.Differences were compared in patients after routine pathological examination.And the distance of the tumor from the anal margin was compared with the preoperative rectum on rectal examination and rectal CT virtual endoscopy.ResultsPreoperative rectum CT virtual endoscopy had no significant difference in evaluation of metastases of the surrounding lymph nodes.Compared with postoperative pathological examination( x2 =2.5,P ＞ 0.05 ),while had significant difference in evaluation in perirectal infiltration( x2 =4.44,P ＜ 0.05 ).Rectal examination and rectum CT virtual endoscopy had no significant difference judgement of the tumor from the anal margin ( P ＞ 0.05 ).ConclusionsCT virtual endoscopy has a great significance in the preoperative evaluation of rectal cancer surgical treatment strategies,which should be further studied.
