Objective To observe therapeutic effects of compounded zedoary turmeric oil suppository com-bined with microwave therapy on cervical erosion. Methods Women with cervical erosion were randomly divided in-to two groups: single microwave therapy group (control group) and compounded zedoary turmeric oil suppository com-bined with microwave therapy group (observation group). The chnical cure rate, obvious effective rate and ineffective rate were compared between two groups. Results In mild erosion, the clinical cure rate, obvious effective rate and ineffective rate were 87.8%, 12.2% ,0 respectively in the observation group. In tbe control group were 85.7%, 14.3%,0 respectively, and there was no significant difference between them (P >0.05); In moderate erosion, were 86.1%, 12.8%, 1.2% respectively in the observation group; were 60.9%, 31.9%, 7.2% respectively in the control group and there was significant difference between them (P < 0.01); In severe erosion, were 59.4%, 34.4%, 6.2% respectively in the observation group; were 29.17%, 41.7%, 29.2% respectively in the control group, and there was significant difference between them (P < 0.05). Conclusion Single microwave therapy to the mild erosion was suf-ficient; nevertheless, compounded zedoary turmeric oil suppository combined with microwave therapy to moderate and severe erosion was better than single microwave therapy.

Objective To investigate the effect of obesity on the early complications after esophageal cancer operation.Methods Clinical data of 327 patients who had esophageal cancer operation in our hospital from August 2012 to September 2015 were retrospectively analyzed.The patients were divided into 4 groups:lean group(n =75), normal group(n =120),overweight group(n =103)and obesity group(n =29)by body mass index(BMI).The impact of obesity on early complications of esophageal carcinoma after surgery was analyzed.Results The operation time of the lean group,normal group,overweight group and obesity group were (257.8 ±52.6 )min,(289.3 ± 48.7)min,(321.5 ±55.9)min,(367.9 ±50.2)min respectively.The operation time was increased with the increase of BMI (F =13.397,P =0.000).The incidence rates of incision infection,empyema,hoarseness,diaphragmatic hernia,postoperative bleeding,chylous fistula,pulmonary complication were 5.3%,1.3%,1.3%,1.3%,2.7%, 2.7%,16.0% in the lean group,5.0%,1.6%,1.6%,1.3%,1.6%,1.6%,17.5% in the normal group,5.8%, 1.9%,0.9%,1.9%,1.9%,1.9%,1.9% in the overweight group,10.3%,3.4%,0.0%,3.4%,3.4%,0.0%, 13.8% in the obesity group.No significant differences were found about the hospital days,wound infection,empyema, hoarseness,diaphragmatic hernia,operation hemorrhage,chylous fistula,pulmonary complications among the 4 groups (all P >0.05 ).The incidence rates of cardiovascular complications and anastomotic leakage after operation were 0.0%,4.0% in the lean group,1.9%,5.0% in the normal group,6.8%,9.7% in the overweight group,13.8%, 17.2% in the obesity group.The incidence of cardiovascular complications,postoperative anastomotic leakage increased with the increase of BMI.The differences of the four groups were statistically significant(F =1.675,1.054, all P <0.05).Conclusion Obesity can increase the incidence of early postoperative complications in patients with esophageal cancer.But obesity is not a contraindication of surgery for esophageal cancer,but obese patients should be more carefully treated in the perioperative period.

[Objective]To study the application and clinical results of the adjustable erternal fixation of ankle joint(AEFA) in orthopedic surgery.[Method]From January 1999 to May 2005,45 cases(55 feet)of equinovarus deformity were treated with orthopedic surgery.In order to preventent the deformity relapsion,the patients were assigned to two groups.The A group(26 cases,32 feet)patients were treated with the adjustable erternal fixation of ankle joint(AEFA).The B group(19 cases,23 feet)patients were treated with plaster immobilization.The orthopedic surgery effect and functions of ankle joint were studied and tested with independent sample t test and x~2 test.[Result]Thirty-eight cases were fellowed-up for 3 months to 9 years(averaged 19 months).There were significant difference between the two groups in the functions of ankle joint.[Conclusion]The new apparatus can effectively prevent the foot-drop deformity and enhance the function of ankle joint.

From March 1982 through December 1083, free transplantation of the perichondrium was used to repair the cartilagenous surface of interphalangeal joints in 5 cases of traumatic comminuted fracture. Of these 5 cases, the injury involved proximal interphalangeal joint of index fingers in 2 cases, proximal interphalangeal joint of the middle finger in 2, and carpometacarpal joint of the thumb in 1. The perichondrium was harvested from the 8th or 9th costal synchondrosis.X-ray film showed growth of new smooth cartilage surface, and the movement of the joints ranging from 10 to 30 degrees was observed 3 months after operation. Points to be observed in operation are: (1) About 0.5 cm of the recipient site of the phalange should be bitten away to expose the cancellous bone, thus a surface with better blood supply was created to receive the perichondrial transplant; (2) The recipient surface was reshaped into an articular surface so that no dead space was left between the recipient surface and the graft: (3) The transplanted perichondrium should be anchored onto the bone under certain amount of tension to insure close contact with the bony surface; (4) Immobilization should be enforced for 3 weeks post-operatively.

Objective To discuss the clinical effect of artificial pneumothorax combined with intercostal nerve block in alleviating chest pain occurring during and after percutaneous microwave ablation (MWA) for subpleural lung malignancy.Methods A total of 30 patients with subpleural lung malignancy were randomly and equally divided into group A (n=10),group B (n=10) and group C (n=10).The patients in group A received both artificial pneumothorax and intercostal nerve block before MWA.The patients in group B only received artificial pneumothorax before MWA,and the patients in group C only received intercostal nerve block before MWA.The degree of pain was evaluated by visual analogue scale (VAS) score during MWA,immediately after MWA and at 6 h,12 h and 24 h after WMA.The side effects after MWA were recorded.Results During MWA,no statistically significant differences in VAS scores existed between each other among the three groups (P=0.885).The VAS scores determined at 6 h,12 h and 24 h after MWA in group C were significantly increased (P=0.014,P=0.006 and P=0.006 respectively).No patient in group A and group B developed symptoms of chest tightness after artificial pneumothorax was performed.After treatment,a small amount of asymptomatic residual pneumothorax was still observed in 6 patients of group A and group B,which disappeared spontaneously in about one week.Another patient still showed massive pneumothorax even after thoracic gas suction,and the patient recovered after thoracic closed drainage for three days.No other serious complications related to artificial pneumothorax occurred.Conclusion Artificial pneumothorax combined with intercostal nerve block can effectively relieve the chest pain occurring during and after MWA in patients with subpleural lung malignancy,and clinically this technique is quite safe.(J Intervent Radiol,2017,26:269-273)

Serum tartrate-resistant acid phosphatase-5b (TRAP-5b) is a marker reflecting bone absorption. The results showed that serum TRAP-5b level was higher in postmenopausal than that in premenopausal normal women (P

Objective To explore the clinical value of early diagnosis of atherosclerosis in patients with systemic lupus erythematosus (SLE) using vascular echo-tracking technique and to detect changes of elastieity of carotid artery quantitatively in SLE patients.Methods Fifry patients with SLE were divided into SLE1 group(duration≤1 year),and SLE2 group(duration>1 year)based on different course.An ultrasonic echo-tracking method was used to measure patients'pressure strain elastic modulus (Ep),the stiffness constant(β),arterial compliance(AC),augmentation index(AI),pulse wave velocity (PWVβ) and intimamedia thickness(IMT)of the common carotid arteries in 50 patients with SLE and in 25 healthy control subjects.Results Among carotid artery elasticity indicators of three groups,there was no significant difference in AI(P>0.05).Ep,β,PWVβ parameters of SLE1 group and SLE2 group were statistically higher than that of the control group[Ep of SLE1 group,SLE2 group,control group was (69±20),(103±40),(48±18)kPa respectively;β was 5.2±1.9,8.0±3.1,4.2±1.3 respectively;PWVβ was 5.2±0.7,6.3±1.1,4.5±0.7]respectively,but AC(AC of SLE1 group,SLE2 group,control group was(1.1±0.3),(0.8±0.3),(1.2±0.6)mm2/k respectively]lower than the controls(P<0.01).Ep,β,PWVβ in SLE2 group was significantly increased compared with SLE1 group,but AC was decreased (P<0.01).Conclusion The application of echo-tracking technology can be used to diagnose early atherosclerosis.Complications of cardiovascular disease in SLE have high clinical value.

Objective To explore the efficacy of transplantation of a U-shaped ilioinguinal flap in the re pair of skin and soft tissue defects of the extremity.An axial flap based on the superficial iliac circumflex artery and trimmed to a subdermal vascular network flap was used for the procedures.Methods Seven patients with skin and soft tissue defects treated between June,2009 and May,2014 were studied.The patients were 22-45 years of age (mean,32 years),and included 5 males and 2 females.Four patients had punch-press injuries,1 patient had a hot-crush injury,and the remaining 2 patients were injured in the accidents.The wound sizes were 14.0 cm × 10.0 cm to 6.0 cm × 5.0 cm,with a varying extent of exposed tendons and bones.Repairs were performed using free ilioinguinal flaps,which were 15.0 cm × 11.0 cm to 7.0 cm × 5.0 cm in size.The axial flap was trimmed to a U-shaped subdermal vascular network flap and transplanted to the recipient site with anastomosis of blood vessels.Results All transplanted flaps survived.Four patients were followed for 1-6 months,with a mean duration of follow-up of 4 months.The trimmed flaps showed gradual reddening immediately after surgery,and the capillaries were recovered with a flat surface.Re-examination 3 months after surgery showed that the flaps were thin and flexible and met the aesthetic demand.No obvious pigmentation occurred,and the donor site was sutured directly,leaving only linear scars.Conclusion Repair of skin and soft tissue defects of the extremity using a U-shaped trimmed ilioinguinal flap has the advantages of a hidden donor site,small scar,and conformity to aesthetic requirements.The trimmed flaps are preferred over untrimmed flaps in terms of color and texture.The former flap is thinner,meets the aesthetic demand,and achieves a better efficacy.

AIM:To observe the effect of Wnt/β-catenin signaling pathway on diabetic ulcer.METHODS:Diabetic animal model was established in the female Wistar rats by intraperitoneal injection of low-dose streptozotocin fol-lowing high-fat diet feeding.A circular wound was made on the dorsum of the rats in both control group and diabetic group. The condition of wound healing was recorded and the structures of the wound tissues were observed by HE staining in the 2 groups at 3, 7 and 14 d after wounding.The expression ofβ-catenin, GSK-3βand Rspo-3 at mRNA and protein levels in the wound tissues was detected by RT-PCR and ELISA.RESULTS:In diabetic group, the wound healing rate was lower (P<0.05), and the inflammatory cells, fibroblast cells and new capillaries in the wound tissues were fewer than those in control group.The expression of β-catenin and Rspo-3 at mRNA and protein levels in the wound tissues in control group was significantly higher than those in diabetic group, and the expression of GSK-3βwas exactly the opposite (P<0.05). CONCLUSION:The down-regulation of Wnt/β-catenin probably resultes from the decreased level of Rspo-3, which may be one of the reasons for delaying the diabetic ulcer healing.
