[Objective]To explore the clinical efficiency,operative methods,apparatus assembly and postoperative administration of Ilizarov technique in the correction of talipes equinovarus.[Method]From January 2003 to May 2006,32 patients were corrected with QIN Si-he's orthotics devices on the Ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.Among these patients,2 were caused by peroneal nerve injury,l by tumor in the vertebral canal,5 by meningocele,11 were caused by poliomyelitis,13 by congenital talipes equino-varus.In accordance with deformities,external fixator and limitied operative methods were dertermined.The limited release of soft tissue were performed in 7 patients,limited osteotomy in 25 patients.The dynamic muscle balance operation were performed in 9 patients with imbalance of muscle strength.According to the Ilizarov technique,the fixative rods were installed.The telescopic rods on the apparatus were rotated one week after the operation,the divices had corrective function in three-dimensional directions.The deformity of talipes equinovarus,internal rotation and drooping of the forefoot were gradually corrected,and the patients could bear weight and walked on the deformed foot.The mean duration of traction were 42 days,then removed the external fixator maintained with plaster for a site time.[Result]All patients were followed up from 12 months to 37 months with an average of 17 months.There was no recurrence of the deformity and feet function was good while walking on full weight-bearing.None of the complication occurred postoperatively sush as infection in the incision,neurovascular injury and ankle dislocation.[Conclusion]With Ilizarov technique to correct talipes equinovarus is a safe,minimally invasive and effective method.Combined with limited operation Ilizarov technique can correct severe talipes equinovarus which is unattainable by traditional orthopedic surgery,and shorten the treatment period,avoid severe complications.

Objective? To explore application effect of personalized nursing in heparin catheter-locking anticoagulant therapy of patients with fractures. Methods? Based on the convenience random number table method, a total of 90 fracture patients in Tangshan Gongren Hospital receiving heparin catheter-locking anticoagulant therapy from June of 2016 to October of 2018 were selected and divided into the observation group and control group with 45 cases in each group. The observation group was given routine nursing during the period of heparin catheter-locking anticoagulant therapy, on the basis of that, the observation group received personalized nursing intervention. The two groups were compared in the disappearance time of symptoms, blood loss after operation, coagulation function [platelet count (PLT), fibrinogen (FIB), D-dimer (D-D)]and complications before and after intervention. Results? The disappearance time of pain, swelling and ecchymosis in the observation group was shorter than that in the control group, but the blood loss was less than that in the control group (P< 0.05); the levels of PLT, FIB and D-D in the observation group were lower than those in the control group (P<0.05); the incidence of complications in the observation group was 8.88%, lower than 26.66% in the control group one month after the intervention (P<0.05). Conclusions? Personalized nursing intervention can improve the nursing quality for fracture patients under heparin catheter-locking anticoagulant therapy and improve their coagulation function and reduce the complications after catheterization.

Objective:To screen the interaction proteins of WW domain containing protein 1 (WWP1), and explore the effects of WWP1 and etoposide induced 24 (EI24) on cell proliferation in hepatocellular carcinoma (HCC).Methods:Yeast two-hybrid screening system was used to identify the interaction proteins of WWP1. The interaction was further validated by co-immunoprecipitation. WWP1 and EI24 stably over-expressing or deleted HepG2 cells were established by using the lentivirus transduction method. Colony forming assay and cell counting kit-8 (CCK8) assay were performed to identify the effects of WWP1 and EI24 on cell proliferation. In addition, the role of WWP1 in the tumorigenicity of liver cancer in vivo was examined by subcutaneous injection of different level of WWP1 expressed HepG2 into nude mice. Results:WWP1 can interact with EI24 and ubiquitin-degrade EI24 protein. The WWP1 and EI24 over-expressing or deleted HepG2 cell lines were successfully generated. Overexpression of WWP1 decreased while knockdown of WWP1 increased the protein level of EI24. The results of CCK-8 assay showed that the relative proliferation activities of WWP1 overexpressed (WWP1-OE) group and WWP1 knockdown (shWWP1) group on 36 hours were (347.00±8.15)% and (187.08±4.86)%, respectively, significantly different from (270.33±15.01)% of control group (both P<0.05). The relative proliferation activities of EI24 overexpressed (EI24-OE) group and EI24 knockdown (shEI24) group on 36 hours were (183.75±8.11)% and (317.33±9.60)%, respectively, significantly different from (270.33±15.01) % of control group (both P<0.05). The results of colony formation assay showed that the colony numbers of control group, WWP1-OE group and shWWP1 group were (52±7)/visual field (VF), (76±4)/VF, (19±3)/VF, respectively. Overexpression of WWP1 significantly increased while knockdown of WWP1 significantly decreased the colon formation ability of HepG2 cells (both P<0.05). The colon number of control group, EI24-OE group and shEI24 group were (38±4)/VF, (10±3)/VF, (69±7)/VF, respectively. Overexpression of EI24 significantly decreased while knockdown of EI24 significantly increased the colony formation ability of HepG2 cells (both P<0.05). The results of xenograft mice model showed that the tumor volumes of control, WWP1-OE, and shWWP1 group were (1 400.00±43.71)mm 3, (2 636.67±290.45) mm 3 and (642.17±36.00)mm 3, respectively, with significant differences ( P<0.05). The tumor weight for these three groups were (1.23±0.08)g, (2.05±0.17)g, and (0.88±0.09)g, respectively, with significant differences ( P<0.05). The tumor volumes of control, EI24-OE, and shEI24 group were (1 245.17±93.10)mm 3, (662.17±60.88)mm 3 and (1 986.67±226.75)mm 3 respectively, with significant differences ( P<0.05). The tumor weight for these three groups were (1.15±0.04)g, (0.85±0.02)g and (1.73±0.05)g respectively, with significant difference ( P<0.05). Conclusion:WWP1 promote the cell proliferation of liver cancer through ubiquitin-degradation of EI24.

Objective We aimed to explore the clinical efficacy of precise electro-acupuncture stimulation in the pterygopalatine fossa for the treatment of chronic sinusitis.Methods In total,40 patients with chronic sinusitis who visited the Xiyuan Hospital,China Academy of Chinese Medical Sciences between January 2022 and January 2023 were selected.The subjects were randomly divided into two groups:the treatment group(receiving precise electro-acupuncture in the pterygopalatine fossa)and the control group(receiving standard western medical treatment),with 20 cases in each groups.The treatments were administered twice a week for a period of 12 weeks.The effectiveness of the treatments was evaluated through computed tomography(CT)of the sinus changes and the Lund-Mackay scoring system.Results In cases of total opacity and partial opacity,there were significant differences between the two patient groups before and after treatment(P<0.05).Intra-group comparison revealed statistically significant improvements in both groups before and after treatment(P<0.05).The treatment group exhibited significant improvement in various sinus conditions(P<0.05),while in the control group,a significant improvement was only observed in the left maxillary sinus(P<0.05).Inter-group comparison also demonstrated that the treatment group's improvements were superior to those of the control group across multiple indicators(P<0.05).Conclusion The precise electro-acupuncture stimulation technique in the pterygopalatine fossa demonstrated significant therapeutic effects in the treatment of chronic sinusitis,with superior outcomes with respect to radiological changes compared to standard western medicine treatment.
