Clinical data of granulomatosa cheilitis of 33 cases were analysed.Odontogenic infectious foci were found in each patient.Elimination of odontogenic infectious foci was followed by regression or disappearance of the swellings in all the 33 cases,suggesting a close relationship between granulomatous cheilitis and odontogenic infectious foci.Elimination of odontogenic infectious foci can be an important measure for the treatment of granulomatous cheilitis.

Objective To investigate the mechanism of homocysteine-induced microglia (BV-2 cells) expression of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α).Methods The BV-2 cells were divided into blank control group,cysteine (Cys) group,homocysteine (Hcy) group and homocysteine and glutathione (Hcy+GSH) group,and the BV-2 cells in these groups were incubated with cysteine or homocysteine or homocysteine and glutathione together for 72 h.The mRNA expressions of IL-1β and TNF-α were assessed by RT-qPCR.The protein expressions of IL-1β and TNF-α in supernatant were detected by enzyme linked immunosorbent assay (ELISA).Western blot was used to observe the changes of NF-κB/p65 expression.Results There were significant differences in mRNA and protein expressions of IL-1β and TNF-α and NF-κB/p65 protein expression between groups (F=48.63,130.76,702.91,293.69,212.06,respectively,all P=0.000).The secretions of IL-1β and TNF-α were significantly improved by homocysteine (P＜0.05),and were reversed by the treatment with glutathione (P＜0.05).Western blot assay result showed that NF-κB/p65 was elevated after treatment with homocysteine (P＜0.05).Conclusions Homocysteine can induce microglia expression of interleukin-1β and tumor necrosis factor-α,and NF-κB signaling pathway may be involved in this process.

Objective: To observe the effects of tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder on pain and shoulder joint function in subacromial impingement syndrome (SIS). Methods: Eighty patients with SIS were recruited and divided into a control group and a treatment group by the random number table method, with 40 cases in each group. The control group was given JIN's three-needle therapy for the shoulder, and the treatment group received additional tendon-regulating and stretching manipulation. The visual analog scale (VAS) score and constant-Murley score (CMS) were observed before and after the intervention, and the total effective rate was also observed. Results: The total effective rate was 92.5％ in the treatment group versus 70.0％ in the control group, and the difference was statistically significant (P<0.05). The VAS score and CMS changed notably after treatment in both groups (P<0.05), and the improvements were markedly greater in the treatment group than in the control group (P<0.05). Conclusion: Tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder can facilitate the relief of pain and the improvement of shoulder joint function in SIS patients.

AIM: To compare the impacts of adriamycin(ADM) intermittent and continuous heat infusion on respiration, heart rate and temperature of the rabbit as well as the concentration of ADM in VX-2 tumor for the verification of the safety and effectiveness of intermittent heat infusion through VX-2 transplanted tumor model in rabbit liver.METHODS: VX-2 tumor models were established respectively in the thighs of 30 New Zealand rabbits. All 30 rabbits were randomly allocated into three groups with 10 rabbits each. After catheterizing into femoral artery, which was demonstrated as the supply artery of tumors by digital subtraction angiography(DSA), animals in three groups were infused with 100 mL saline at normal temperature and ADM, 100 mL saline at 60 ℃ and ADM continuously and 100 mL saline at 60 ℃ and ADM intermittently respectively. During infusion, the 43 ℃ to 45 ℃ lasting time in the tumor tissues of the two 60 ℃ groups was measured. After infusion, the respiration(time/minute), heart rate(beats/minute) and temperature(℃ )of the rabbits in each group as well as the concentrations of ADM in tumor tissue were measured immediately.RESULTS: The concentration of ADM was (7. 1 ± 2.2) mg/L in normal temperature infusion group, (17.2 ± 1.6) mg/L in 60 ℃ continuous infusion group and(16.5 ±3.4) in 60 ℃ intermittent infusion group. There were significant differences among three groups( F = 48.95, P = 0. 000), but there was no significant difference between 60 ℃ intermittent infusion group and 60 ℃ continuous infusion group( P ＞ 0. 05). 43℃ to 45 ℃ lasting time was(22.5 ±1.4) minutes in 60 ℃continuous infusion and (24.3±2.4)minutes in 60 ℃intermittent infusion group( F =4.20, P ＞ 0.05) . There were significant differences among three groups in respiration, heart rate and temperature( F = 14. 58, 33.07, 10.00, P ＜ 0.01), but there was no significant difference in the respiration, heart rate and temperature between 60℃ intermittent infusion and normal temperature infusion group ( P ＞ 0. 05).CONCLUSION: Intermittent thermochemotherapy is a more effective and safe interventional thermochemotherapy method compared with continuous heat infusion.

Objective To compare two operative approaches for treatment of distal hypospadias. Methods One hundred and seven patients were recruited into the study. Group1(n=51) underwent OUPF and group2(n= 56) underwent TIPU repair. The results were analyzed with Chi-square and two Sided test. Results Operative times for OUPF and TIPU repair were (103±29) min and (92±21)min respectively (P>0.05). Fistula occurred rates were 7.8% (4/51)and 14.2% (8/56) (P>0.05). Satisfied rates for the appearance of the penis post-operation were 84.8% (39/46)and 87.8%(36/41) respectively (P>0.05). 87 patients were followed up. With mean follow-ups of 15 months (range 6 to 47) , the overall complication rates were 15.7% (8/51) and 32.1 % (18/56)(P<0. 05) for OUPF and TIPU repair. Only 4 of 51 patients (7.8%) undergoing OUPF underwent re-operations, compared to 15 of 56 patients (26.8%) undergoing TIPU repair (P<0.001). A plateau uroflow curve (vs normal bell curve)was observed in 33.3% (13/39)and 67.6(25/37) ,respectively(P<0. 001). The average flow rate was 9. 4 ml per second (range 3. 2 to 17. 1) in patients undergoing OUPF repair, compared to 6. 8 ml per second (3. 3 to 15, P<0. 05) for those undergoing TIPU repair. Mean peak flow rates were12.2 ml per second (range 3.9 to 22.9) and 8. 3 mi per second (range 3.7 to 18. 1, P<0.01) for OUPF and TIPU procedures. Conclusion OUPF is superior to TIPU in the surgical treatment of distal hypospadias.

OBJECTIVE: To evaluate the instructional effect of Multi-slice (MSCT) in the cochlear implantation pre- and post-operatively, and to contrast the image feature between the X-ray and the MSCT three-dimensional reconstruction of inner ear with implanted electrode. METHOD: Twenty-four cochlear implant (MEDEL Combi 40+) recipients,in No. 1 Hospital of China Medical University from January to October 2014, were involved in this study. Among them, 18 were male and 6 female,with an average age of 4 years. MSCT and three dimensional reconstruction of inner ear were performed in all of the 24 implanted inner ears pre- and post-operatively. And X-ray plain film were examined by using 60° lateral oblique position postoperatively. All data of the spiral CT scan with axial 1 mm image slices were transferred to workstation for three-dimensional reconstruction (direct volume rendering) of the inner ear. RESULT: In 1 of the 24 cases, preoperative three-dimensional reconstruction CT scan reveal that the length of the cochlear was shorter than the electrode. And this was confirmed by MSCT postoperatively that the electrode couldn't be inserted by full length. The insertion depth of the electrode can be evaluated directly by MSCT. Moreover, each of the electrode pairs can be identified clearly. CONCLUSION MSCT plays an indispensable role in the preoperative evaluation of cochlear implantation. Postoperative evaluation by three-dimensional reconstruction of inner ear provide more accurate image to show the electrode insertion depth in the cochlea. MSCT combined with curved planar reformation to measure cochlear length could provide guidance in choosing the more adaptive electrode. And MSCT is superior to DR in demonstration of electrode postoperatively.

Objective: To observe the expression changes of insulin-like growth factor 1 (IGF-1) and mammalian target of rapamycin (mTOR) in the peripheral blood of patients with advanced non-small cell lung cancer (NSCLC) treated with chemotherapy combined with metformin, and to elucidate its mechanism. Methods: Sixty patients with NSCLC were divided into chemotherapy group (15 cases of adenocarcinoma and squamous cell carcinoma, treated with chemotherapy alone) and combination group (15 cases of adenocarcinoma and squamous cell carcinoma, treated with chemotherapy combined with metformin). The expression levels of IGF-1 and mTOR protein and mRNA in peripheral blood of the patients in two groups were detected by ELISA and quantitative real-time PCR (QT-PCR) method. Pearson univariate analysis and multivariate logistic regression analysis were used to analyze the influencing factors of the treatment of patients with advanced NSCLC; the curative effect was comprehensively evaluated. Results: Compared with chemotherapy group, the differences of the levels of IGF-1 and mTOR and the mRNA expression levels of IGF-1 and mTOR of the patients in combination group before and after treatment were decreased (t=-3.207, P=0.003; t=2.414, P=0.019; t=-3.635, P= 0.001; t=-3.737, P=0.001). In adenocarcinoma, compared with chemotherapy group, the differences the levels of IGF-1 and mTOR and the mRNA expression levels of IGF-1 and mTOR of the patients in combination group before and after treatment were decreased (t=5.270, P<0.01; t=2. 816, P= 0.009; t=-2. 621, P= 0.019; t=4. 039, P<0.01); in squamous cell carcinoma, compared with chemotherapy group, the differences of the levels of IGF-1 and mTOR and the mRNA expression levels of IGF-1 and mTOR in peripheral blood of the patients in combination group before and after treatment were reduced (t=4. 164, P<0.01; t=2.670, P=0.012; t=3.072, P=0.008; t=3.502, P=0.002). From the level of disease control rate, the total effective rate of the patients in combination group (80.0%) was significantly higher than that in chemotherapy group (53. 3%) (P<0.05). The univariate analysis results showed that gender, smoking, tumor stage, and lymph node metastasis were related to the therapeutic effects of the patients in two groups (P<0.05); the ECOG score and tumor differentiation degree were related to the therapeutic effect of the patients in chemotherapy group (P<0.05), and pleural effusion was related with the therapeutic effect of the patients in combination group (P<0.05). The results of multivariate analysis showed that smoking and tumor stage were the independent risk factors of the patients in two groups (P<0.05), and smoking and lymph node metastasis were the independent risk factors of the patiens in chemotherapy group (P<0.05); smoking, differentiation, and pleural effusion were the independent risk factors of the patients in combination group (P<0.05). Compared with chemotherapy group, the incidences of bone marrow suppression, gastrointestinal reactions, nephrotoxicity, and liver damage of the patients in combination group had no significant differences (P>0.05). Conclusion: Chemotherapy combined with metformin is more effective in the treatment of the patients with NSCLC and can reduce its adverse reactions, its mechanism may be related to the reduction of IGF-1 and mTOR levels in the peripheral blood of the patients.

Objective To evaluate the efficacy of 1-stage urethroplasty using pedicle circular fascioctaneous preputial flap for the treatment of complex anterior urthral strictures.Methods Between January 2006 and January 2013, 37 patients with complex anterior urethral stricture were treated by 1-stage urethroplasty using pedicle circular fascioctaneous preputial flap.The mean age was 41 years ( 22 -71 years) .The etiology of stricture included trauma of 13 cases, iatrogenieity of 13 cases, gonorrhea infection of 2 cases, unknown reason of 9 cases.The penile urethral stricture was found in 22 cases, the bulbourethral stricture in 9 cases, and stricture extending from penile to posterior urethra in 6 cases.The mean length of anterior urethral stricture was 8.1 cm (range 5.0-14.0 cm).A circumferential island of the preputial/distal penile skin was mobilized by the technique of preserving penile fasciocutaneous wide vascular pedicle. The pedicle is composed of two layers of the dartos and the superficial lamella of Buck′s fascia, and the flap was divided in the midventral/middorsal plane back to the penoscrotal junction to convert the circular configuration to a longitudinal trip for urethral reconstruction.The dorsal and ventral inlaid flap urethroplasty was performed in 27 cases and tubularized flap urethroplasty was performed in 10 cases.Results The mean operative duration was 3.1 h (2.5-3.5 h).The mean length of the circular fascioctaneous preputial flap was 10.4 cm (range 9.0 -14.0 cm).All the patients were followed up for mean 22 months (3 -51 months).Thirty-two cases voided well and the mean peak urinary flow rate was 22.3 ml/s (15.0-29.0 ml/s).One-stage healing achieved in 32 cases (86.5%).Recurrent stenosis was noted in 4 cases, and meatal stenosis occurred in 1 patient, who required re-operation.Re-repair succeeded in 4 cases and total success rate was 97.3% (36/37).Conclusions The pedicle circular fascioctaneous preputial flap has advantage of good blood supply and autograft for new meatus.It could be a reliable and durable method for the treatment of complex anterior urthral strictures(≥5 cm) in 1-stage urethroplasty.
