Objective To investigate the effect of narrow-band UVB combined with tacrolimus ointment in the treatment of vitiligo,and its influence on IL-17 and IL-22 in peripheral blood.Methods 100 patients with vitiligo were selected as study subjects,and they were divided into the control group and observation group according to the random number table method,50 cases in each group.The control group was given 0.1% tacrolimus ointment,the observation group was treated with narrow-band UVB combined with 0.1% tacrolimus ointment.After 6 months of treatment,the clinical treatment effect of the two groups was observed.The levels of serum IL-17 and IL-22 were detected by ELISA,the differences between before and after treatment were compared between the two groups.Results The cure rate,effective rate of the observation group were 74.0%,96.0%,respectively,which were significantly higher than 62.0%,84.0% of the control group,the differences were statistically significant(x2=3.125,2.897,all P<0.05).The levels of IL-17 and IL-22 in the two groups before treatment had no statistically significant differences(all P>0.05).After treatment,the levels of IL-17 and IL-22 in the two groups significantly decreased(t=3.454,3.032,all P<0.05),which in the observation group were lower thanthose in the control group(t=3.867,2.665,all P<0.05).Conclusion Narrow-spectrum UVB combined with tacrolimus ointment has good clinical effect on vitiligo,which can effectively improve the local immune response.

Objective To investigate the effect of compound glycyrrhizin combined with fexofenadine hydrochloride in the treatment of chronic urticaria and its effect on plasma histamine.Methods 100 patients with chronic urticaria were selected as study objects,and they were divided into the control group(50 cases) and observation group(50 cases) according to the random number table method.The control group was treated with fexofenadine hydrochloride,while the observation group was treated with compound glycyrrhizin on the basis of the control group.The clinical effect and plasma histamine level were compared between the two groups.Results The effective rate of the observation group was 96.0%,which was significantly higher than 84.0% of the control group(χ2=7.951,P<0.05).After treatment,the plasma histamine content of the observation group was (2.38±0.26)ng/mL,which was lower than (3.10±0.29)ng/mL of the control group,and the difference between the two groups was statistically significant(t=6.084,P<0.05).Conclusion The compound glycyrrhizin combined with fexofenadine hydrochloride in the treatment of chronic urticaria can reduce the symptoms of the patients,reduce the number and size of the patients and effectively control the clinical symptoms of the patients.And it can effectively reduce the level of plasma histamine in patients with good clinical effect and application value,it is worth to be promoted in clinical.

Objective To evaluate the effect of total mesorectal excision with single stapling technique for low positioned rectal cancer.Methods Based on total mesorectal excision,56 cases of low positioned rectal cancer underwent anal preserving operation with single stapling technique and purse-string forceps.The 2 years follow-up result was retrospectively analyzed on radical resection effect,defecating function,complication rate and recurrent rate.Results All the resection margins were clear and had no intraoperative death,anastomotic leakage or occurrence of incontinence.Anastomotic stricture rate was 4%(2/56) and local recurrent rate was 5%(3/56).The patients were satisfied with anal function.Conclusion Based on total mesorectal excision,anal preserving operation for low positioned rectal cancers using single stapling technique and purse-string forceps can improve the postoperative quality of life,that is safe,feasible,practical and economical.

Objective To investigate the effect and mechanism of ultrashortwave(USW)diathermy and rotating magnetic(RM)field therapy on the brain following transient focal cerebral ischemia and reperfusion in rats. Methods Fifty-two Wistar rats were randomly divided into a sham operation group, an ischemia and a reperfusion control group, a USW treatment group and a RM treatment group. Focal cerebral ischemia and reperfusion were induced by intraluminal filament occlusion of the middle cerebral artery. Each brain was removed at 24 h after the reperfusion and water content, cerebral infarct volume and histological expression of Bcl-2 and Bax proteins were observed. Results When USW treatment was started at 18 h after reperfusion, decreased infarct volume and water content were observed, but RM treatment did not show this relationship. Both USW and RM were associated with increased expression of Bcl-2 protein and decreased the expression of Bax protein. Conclusions USW treatment is beneficial in focal cerebral ischemia. RM′s effect is uncertain. Any effect is through reducing apoptosis.

Objective:To discuss the anti-rheumatoid arthritis activity and mechanism of hospital preparation Erteng Tongbi gran-ule ( ETTB) . Methods:The collagen-induced arthritis ( CIA) animal model in DBA/1 mice was established and treated with high, medium and low dosage of ETTB. Blank control, model control and methotrexate group were also established. The influences of ETTB on BMI, arthritis index, ankle joint destruction and expression of serum cytokine TNF-α and IL-6 in CIA mice were observed. Re-sults:Compared with the control group, ETTB at high dose (6g?kg-1) could significantly decrease the arthritis index of CIA mice (P<0. 05), and the joint damage on the 14th day was also significantly improved. ELISA results showed that ETTB at high dose could significantly inhibit the secretion of cytokine TNF-αand IL-6 when compared with the model group (P<0. 01). Conclusion:Hospital preparation ETTB has anti-rheumatoid arthritis activity, and its mechanism may be related with the inhibition of cytokine secretion.

Colorectal cancer is one of the most common malignant tumors. The recent successful development of targeted therapy has brought new hope for patients with colorectal cancer. Two monoclonal antibodies, bevacizumab and cetuximab, that block vascular endothelial growth factor and epithelial growth factor receptor are available widely in clinical practice. This clinical review focuses on the role of targeted therapy in the management of colorectal cancer.

Objective To explore the effect of cryotherapy and compression system in rehabilitation treatment for reconstruction of anterior cruciate ligament.Methods One hundred and twenty patients who had been treated with reconstruction of anterior cruciate ligament were randomly divided into treatment group (60 patients,treated with cryotherapy and compression system) and control group (60 patients,treated with traditional method).All patients was treated for 3 months and followed up for 6 months.The scores of visual analogue scales(VAS),degree of swelling,Lysholm and IKDC scores were observed and compared.Results The scores of VAS in treatment group postoperative 6,24 and 48 h were significantly lower than those in control group (P ＜ 0.01).The degree of swelling in two groups postoperative 6 h,12 h,24 h,48 h,1 week,2 weeks had significant difference(P ＜ 0.05).The degree of swelling in treatment group postoperative 4 weeks,3 months and 6 months was lower than that in control group,but there was no significant difference (P ＞0.05).The scores of Lysholm and IKDC in treatment group postoperative 4 weeks were (65.2 ± 12.3),(65.3 ± 14.3) scores,in control group were (60.2 ± 12.5),(59.4 ± 13.5) scores,there was significant difference (P ＜0.05).The scores of Lysholm and IKDC in two groups postoperative 3,6 months hod no significant difference (P ＞ 0.05).Conclusion The cryotherapy and compression system in rehabilitation treatment for reconstruction of anterior cruciate ligament can improve the effect of early-term rehabilitation training,but has little impact on the long-term rehabilitation training.

Objective To discuss the microcosmic elements and syndromes distribution of H pylori-related gastritis. [Method] Choose 100 cases, under gastroscope report, make statistics of frequency of disease nature elements and location elements, combine the nature and location for common syndromes. [Result] The H pylori-related gastritis has main disease location elements in stomach, esp. the sinuses ventriculi;the disease nature elements mainly concern hot, wet, sputum stasis, deficiency and blood stasis; the common syndromes: hot stomach, sputum and stasis blocking stomach, wet-hot accumulated in stomach, deficient stomach, wet stranding stomach and stasis blocking gastric col aterals. [Conclusion] Over the inconsistent syndromes in clinical H pylori-related gastritis, the microcosmic elements differentiation can further standardize syndromes and guide the treatment.
