OBJECTIVETo explore the clinical efficacy and effect mechanism on chronic urticaria treated with moving cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints.

METHODSOne hundred and four patients of chronic urticaria were randomized into a comprehensive therapy group and a medication group, 52 cases in each one. In the comprehensive therapy group, the moving cupping therapy along the governor vessel and bladder meridian of foot-taiyang was applied combined with autohemotherapy with acupaint injection for desensitization at acupoints. The self-venous blood was injected at bilateral Quchi (LI 11) and Zusanli (ST 36), 1 mL at each acupoint, once every 3 days. In the medication group, cetirizine tablets, 10 mg were prescribed for oral administration, once every day, and the compound dexamethasone acetate cream was used externally, once to twice a day. The clinical efficacy: was observed in 30 days of treatment in the two groups. The changes of serum interleukin 4 (IL-4) and immunoglobulin E (Ig E) before and after treatment were observed. The recurrence rate was compared between the two groups in 3 months after treatment.

RESULTSThe cured and markedly effective rate was 90.4% (47/52) in the comprehensive therapy group, which was higher obviously than 78.8% (41/52, P < 0.05) in the medication group. The levels of serum IL-4 and IgE were reduced in the patients of the two groups, indicating the significant difference in comparison before and after treatment (all P < 0.01) and the reducing degree in the comprehensive therapy group was much more significant than that in the medicine group (both P < 0.01). The recurrence rate was 19. 1% (9/47) in the comprehensive therapy group in the 3-month follow-up after treatment, and apparently lower than 51.2% (21/41, P < 0.01).

CONCLUSIONThe moving cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints achieves the better efficacy on chronic urticaria compared with the routine western medicine treatment and the recurrence rate is low. The effect mechanism is possibly related to the down-regulation of serum IL-4 and IgE in the patients.

·AIM: To investigate the effect of vitamin A on the conjunctival goblet cells of rat after corneal transplantation.·METHODS: Rat graft rejection models of corneal transplantation were established. SD rats were receptor and Wistar rats were donors. After corneal allografts were performed, 48 SD rats were randomly divided into three groups, 16 rats in each group. Group A was blank control group; group B was treated by oculotect gel (containing vitamin A); group C was treated by 1g/L dexamethasone eyedrops. Besides, group D was normal unoperated eyes.Slit-lamp microscope was employed to record and compare rejection index (RI) of corneal transplantation. Through HE,PAS staining of conjunctival histological sections and image analysis system, the number and morphology of conjunctival goblet cells were observed and analyzed between operation group and normal group.·RESULTS: The HE, PAS staining detection showed that the number of conjunctival goblet cells in oculotect gel group,1g/L dexamethasone eyedrops group and control group is lower than that in normal group after surgery (P＜0.01). The number of conjunctival goblet cells in oculotect gel group and 1g/L dexamethasone eyedrops group is higher than that in control group (P＜0.05). The number of conjunctival goblet cells in 1g/L dexamethasone eyedrops group is higher than that in oculotect gel group (P＜0.05).·CONCLUSION: The results indicate that vitamin A may inhibit the decrease of conjunctival goblet cells after corneal allograft rejection in rats.

BACKGROUND:The physicochemical properties and bioactivity of titanium surface will degrade with time because of the aging phenomenon,affecting the efficiency of implant-bone osseointegration.Therefore,the re-activation of the implant surface physicochencical properties and bioactivity is important.OBJECTIVE:To investigate the re-activation effect of ultraviolet rays on aging titanium surface.METHODS:Sand-blasted and acid-etched titanium discs were divided into three groups randomly:Group A was new titanium surface,Group B was stored in a sealed container for 4 weeks,Group C was treated with ultraviolet rays for 15 minutes after stored in the sealed container for 4 weeks.The surface roughness,elemental composition and surface energy of the titanium surface were examined by optical profilometer,X-ray photoelectron spectroscopy and contact angle measuring device,respectively.The bioactivity of the titanium surface was examined by cell culture experiments.MG63 osteoblast-like cells were cultured on the different titanium surfaces.After 30 minutes,1,2,4 hours of incubation,the cells were strained with Hoechst33342 fluorescence,and initial attachment of cells was evaluated by measuring the amount of cells attached to the titanium surface.The proliferation of cells was quantified in terms of cell density at 1 and 3 culture days using tetrazolium salt (MTS)-based colorimetry.RESULTS AND CONCLUSION:There was no obvious difference in the surface roughness of the three groups,and ultraviolet treatment did not change the surface morphology of titanium surface.X-ray photoelectron spectroscopy showed that the C element content of group A and group C was lower than that of group B (P ＜ 0.05),and the content of Ti,O,N elements was significantly higher than that of group B (P ＜ 0.05).No difference in the surface element composition between group A and group C was found.Both of the surface contact angles of group A and group C were Oo,but in group B,the value was 115°.The number of initially attached cells of group A and group C was significantly higher than that of group B after incubated 30 minutes,1,2 and 4 hours (P ＜ 0.05),and no difference between group A and group C was found.The proliferation of cells of group A and group C was significantly higher than that of group B after incubated 1 and 3 days (P ＜ 0.05),but no difference between group A and group C was found.In conclusion,ultraviolet rays show good effects on the re-activation of the aging titanium surface,which can reduce hydrocarbon contamination and recover the high surface energy to increase cell adhesion and proliferation.

Objective To explore the predictive value of ventricle late potential (LP) for arrhythmic events in the patients with Brugada syndrome. Methods Totally 43 patients with Brugada syndrome were divided into symptom group (n=24) and asymptom group (n=19).Signalaveraged electrocardiography(SAECG) was performed to analyze characteristics of LP in all subjects.The occurrence of arrhythmic events was observed in all patients during the dynamic follow-up for (33.8±9.0) months.Results There were 22 cases (91.7％) and 7 cases (36.8％) with LP positive in patients with symptom and asymptom,respectively.The incidences of arrhythmic events were 72.4％ in Brugada syndrome patients with positive LP and 14.3％ in patients with negative LP,respectively.The relative risk (RR,95％ CI) for LP prediction of the arrhythmic events was [5.1,(1.4～ 18.6)] (P =0.002). ConclusionsLP may be one of effective factors predicting arrhythmic events in the patients with Brugada syndrome.

Objective To investigate the expression of apolipoprotein M in rats after renal transplantation and its role and action mechanism in acute rejection (AR).Methods The kidney transplantation model in rats were established.Male SD and Wistar rats were used as donors,and Wistar rats as recipients.Three groups were designated:control group (syngeneic transplantation,n =24,recipients were treated with normal saline i.p.); AR group (allogeneic transplantation,n =24,recipients were treated with normal saline i.p.); PDTC group [allogeneic transplantation,n =24,recipients were treated with NF-κB inhibitor-pyrrolidine dithiocarbamat (PDTC) i.p.].The renal grafts were drawn at day 1,3,5 and 7 post-transplantation,and the expression levels of NF-κB P65 and apoM protein were detected by using Western blotting,and those of apoM,perforin and granzyme B mRNA were by using real-time PCR.The correlation of apoM and NF-κB,apoM and perforin,and apoM and granzyme B was respectively analyzed.Results As compared with control group,the expression levels of apoM,perforin and granzyme B mRNA in AR and PDTC groups were dramatically up-regulated at each time point (P＜0.01),and those in PDTC group were significantly lower than those in AR group (P＜0.01).The expression levels of apoM and NF-κB protein in AR group were both distinctly higher than those in control group (P＜0.01),and those in PDTC group were markedly lower than those in AR group (P＜0.01).A significantly positive correlation was found between the expression of apoM and NF-κB protein (r =0.469,P＜0.05).And the expression of apoM mRNA was positively correlated to perforin and granzyme B mRNA (r =0.731,P＜0.01 ; r =0.514,P＜0.05).Conclusion The expression of apoM is obviously up-regulated in renal grafts of rats,which may take part in the pathogenesis of AR via NF-κB.

Objective To investigate the expression of periostin in the kidneys of rats with obstructive nephropathy and its relevance to renal interstitial fibrosis.Methods Eighteen male adult SD rats were randomly divided into sham group,model group and benazepril group (6 in each group).Unilateral ureteral obstruction (UUO) model was induced by ligating the left ureter of rats.RT-PCR was used to detect the mRNA expressions of periostin and TGF-β1,and ELISA to detect the protein expression of periostin,Ang Ⅱ,and TGF-β1 in kidney tissue.Pathological changes of renal tissue were observed by HE and Masson staining.The protein expression of collagen Ⅰ (Col Ⅰ ) in kidney tissue was examined by immunohistochemical staining.Results The mRNA expressions of periostin and TGF-β1 in model group increased markedly as compared with sham group (all P＜0.05),and benazepril could decrease these mRNA expressions (all P＜0.05).The protein expressions of periostin,Ang Ⅱ and TGF-β1 in kidney tissue were significantly increased in model group as compared with sham group (all P＜0.05),and benazepril could decrease these protein expressions (all P＜0.05).The expression of periostin in kidney tissue was positively correlated with the expressions of Ang Ⅱ,TGF-β1 and Col Ⅰ,as well as the degree of renal interstitial fibrosis (r=0.652,0.781,0.776 and 0.825 respectively,all P ＜0.05).Conclusion Periostin expression is up-regulated in kidney tissue of rats with obstructive nephropathy,which is associated to the over-deposition of extracellular matrix (ECM) in the kidneys of UUO rats.

BACKGROUND: The proximal tibia is the second common site for primary bony sarcomas,which lacks adequate soft tissue coverage.Resection and reconstruction by any technique leave the reconstructed area in a subcutaneous position.This has been a major source of necrosis of skin and infections.OBJECTIVE: To observe the effect of gastrocnemius muscle transfer to obtain soft-tissue coverage and extensor mechanism reconstruction for limb-sparing resection of the proximal tibia with endoprosthetic reconstruction.METHODS: From January 2001 to June 2008,27 patients with osteosarcoma of the proximal tibia confirmed by biopsy were selected.All the tumours were assigned to stage IIB based on Enneking's classical staging system.Neoadjuvant chemotherapy(Bacci,IOR/OS-N4)was utilized for the patients.All the patients adopted limb-sparing surgery,i.e.resection of proximal tibia with endoprosthetic reconstruction.A gastrocnemius flap was utilized to improve implant coverage and enhance the patellar tendon repair.MSTS was used to measure the functional status of patients with a sarcoma in the leg.RESULTS AND CONCLUSION: The follow-up was averagely 53.1 months.Of 27 patients,2 cases(7%)died of lung metastasis within 2 years,1(4%)suffered from amputation due to infection and underwent amputation.The others developed no complications or recurrence.The MSTS score was averagely 25.1 points.Results show that resection with endoprosthetic reconstruction utilizing a gastrocnemius muscle flap for osteosarcoma of the proximal tibia is reliable and predictable in combination with neoadjuvant chemotherapy.

Objective To investigate the surgical technique,postoperative function and dislocation incidence of proximal humerus reconstruction with metallic endoprostheses and polypropylene knitted nonabsorbable mesh after proximal humeral tumor resection.Methods Twenty patients with proximal humeral tumor were retrospectively reviewed.They were performed proximal humerus reconstruction with proximal humeral prosthesis and polypropylene knitted non-absorbable mesh from February 2006 to January 2009.There were 5 women and 7 men with a mean age of 38 years(range,21-55 years)at the time of surgery,and giant cell tumor in 9 patients(including Campanacci Ⅱ for 3,Campanacci Ⅲ for 6),osteosarcoma in 1(Enneking ⅡB).and chondrosarcoma in 2 (Enneking ⅡA).The operative time,blood loss,and shoulder movement postoperation were analysed.According to the assessment system by MSTS,the function of limb after surgery was assessed.Results Patients were followed clinically and radiographically for a minimum of 24 months (mean,35 months;range,24-52 months).The mean operative time was 172 min(range,150-200min).The mean blood loss was 254 ml (range,150-500 ml).There were no shoulder dislocations at final follow-up.The mean shoulder flexion was 41°(range,20°-60°)and mean shoulder abduction was 42°(range,20°-70°).The mean postoperative functional assessment score of the limb was 66%(range,53%-77%).None of the Datients had a wound infection,traction neuropraxia or died after the surgical procedure.Conclnsion The data suggests that the use of a polypropylene knitted non-absorbable mesh for proximal humerus reconstruction may reduce dislocations and facilitate soft tissue attachment after tumor resection.
