Objective To study the relationship between serum levels of C reactive protein,adiponectin and severity of disease,joint function in patients with rheumatoid arthritis(RA).Methods A total of 85 cases of RA treated in our hospital from September 2014 to August 2016 were selected into the RA group,and 20 healthy persons were recruited into control group.The serum C reactive protein,adiponectin were detected,compared in the two groups,and to investigate the relationship between them with severity of disease,joint function of the patients.Results C reactive protein of RA patients was(23.63±5.36) pg/mL,which was significant higher than that of the control group,the adiponectin,the ratio of C reactive protein and adiponectin were(4.64±1.74)ng/mL,0.37±0.06 respectively,which were significant lower than those of the control group,the differences were statistically significant(P<0.05).RA patients with more serious joint injury and disease status,the adiponectin,the ratio of adiponectin and C reactive protien were more lower,the C reactive protien was more higher,the differences in different joint injury and disease status groups were significant(P<0.05).Logistic analysis showed that adiponectin(P=0.04),the ratio of adiponectin and C reactive protien(P=0.01) were independent risk factors of bone damage in RA patients.Conclusion Serum C reactive protein and adiponectin level were closely related to the severity of RA and joint function.

Objective To Summarize the application of digital artery dorsal distal interphalangeal joint perforator flap to repair finger tip skin defect,and at the same time,the method and effect of anastomosis of finger dorsal branch of digital nerve sensory reconstruction.Methods From September 2012 to March 2015,78 patients 92 fingers were treated in Orthopedics Department of Jinshan Branch Hospital of the Sixth People′s Hospital of Shanghai,all patients with finger artery distal interphalangeal joint dorsal cutaneous branches of the dorsal flap pedicled with retrograde,transferred to repair the skin defect of finger end,and anastomosis of dorsal branch of the proper digital nerve reconstruction.Results Postoperative vascular crisis occurred in 8 cases,2 cases of partial flap necrosis and healed after symptomatic treatment.All flaps survived,the wounds healed in I stage,and the donor site healed in I stage.All the 73 cases were followed up,the follow-up period ranged from 3.0 to 12.0 months,an average of (7.8±2.5) months.The postoperative appearance and feel good,soft texture,abrasion resistance,no tenderness,cold resistance,dynamic two-point recovered to 4.0-8.0 mm,average (5.3±0.9) mm.Static two-point discrimination was 4.0-9.0 mm,average (5.8±1.2) mm.The method of TAM was used to determine the function of the 67 fingers,good for the 7 finger,but also for the 5 finger and the difference of the 0 finger.The excellent and good rate was up to 93.7%.Conclusion The operation without sacrifice of major arteries and nerves by finger,the middle finger dorsal skin for non functional surface area,and at the same time by anastomosis of dorsal branch of the proper digital nerve reconstruction,without surgery two times,is one of the ideal surgical repair of skin defect of the finger end.

Objective To compare the clinical efficacy of hollow screws and "L" type plate for the treatment of middle and lower 1/3 spiral fracture of tibia combined with posterior malleolar fracture.Methods A retrospective case control study was performed on the clinical data of 73 patients with middle and lower 1/3 spiral fracture of tibia combined with posterior malleolar fracture treated from January 2010to January 2017.There were 47 males and 26 females,with the mean age of 38.5 years (range,23-70 years).According to the posterior malleolus fixation method,38 cases adopted the internal fixation with three hollow screws (screw group),and 35 cases with" L" type plate fixation (plate group).The middle and lower 1/3 spiral fracture of tibia were treated with medial anatomical plate internal fixation.The intraoperative blood loss,operation time,infection,fracture healing time,and complications were recorded.The Baird-Jackson score was used to evaluate the ankle joint function.Results There were no significant differences in the blood loss and operation time between the two groups (P ＞ 0.05).A total of 71 patients were followed up for 6-18 months (mean,15.8 months).Two cases in the screw group were lost to follow up.The wounds healed well after operation in two groups,and no signs of wound infection were found.All fractures healed well without delayed union or nonunion.There was no significant difference in fracture healing time between the two groups (P ＞ 0.05).No obvious reduction loss in posterior ankle fracture was found during follow-up.In the plate group,one patient was seen vertical shape toe deformity after operation,which might be related to muscle spasm of flexor hallucis longus,and the condition was not improved after removing the plate.At the last follow up,ankle joint function was evaluated according to the Baird-Jackson scoring system:in the screw group,18 cases were excellent,13 cases were good,four cases were allowed to pass,and one case was poor,with the excellent and good rate of 82％;in the plate group,17 cases were excellent,13 cases were good,four cases were allowed to pass,and one case was poor,with the excellent and good rate of 86％ (P ＞ 0.05).Conclusion The clinical efficacy of hollow screws and "L" type plate is not significantly different,both of which can provide rigid fixation,reduce the incidence of hip dysfunction and improve quality of life of patients with middle and lower 1/3 spiral fracture of tibia combined with posterior malleolar fracture.

Objective:To investigate the clinical outcome of arthroscopic suture-button Bristow procedure using suture-button fixation for treatment of recurrent anterior shoulder instability.Methods:A retrospective case series study was conducted to analyze 28 patients with recurrent anterior shoulder instability admitted to Shanghai Sixth People’s Hospital from March 2015 to September 2018，including 26 males and 2 females，aged 18-36 years ［（24.1 ± 3.2）years］. Preoperative MRI showed Bankart injury and three-dimensional CT showed glenoid bone defect > 15%. The Hill-Sachs injury was found in 27 patients. Arthroscopic Bristow procedure was used to fix coracoid process graft with the suture-button plate and glenoid labial complex was repaired with the suture anchor to treat anterior instability of the shoulder joint. The visual analogue scale （VAS），American shoulder and elbow surgeon （ASES） scale，Constant score and Rowe score were used to evaluate the shoulder joint function preoperatively，at postoperative 3，6，12 months and at the last follow-up. The postoperative infection，neurovascular injury，redislocation and other complications were recorded，and the incidence rate was calculated. The bone resorption and bone healing of coracoid process graft were analyzed by CT.Results:All patients were followed up for 22 - 36 months ［（24.5 ± 6.3） months］. Three months after operation，the VAS，ASES scale and Constant score were not significantly different from those before operation （ P > 0.05）. In comparison，the Rowe score was significantly higher than that before operation （ P < 0.05）. Six and twelve months after operation，the VAS，ASES scale，Constant score and Rowe score were significantly improved from those before operation （ P < 0.05）. At the last follow-up，the VAS decreased from （2.7 ± 1.5）points preoperatively to （0.8 ± 0.3）points，the ASES scale increased from （78.6 ± 12.7）points preoperatively to （92.4 ± 8.4）points，the Constant score increased from （43.4 ± 5.2） points preoperatively to （81.6 ± 6.7） points，the Rowe score increased from （52.3 ± 7.1）preoperatively to （92.7 ± 5.4） points （ P < 0.05）. During the follow-up，there was no infection，neurovascular injury，re-dislocation and other complications. In addition，24 （86%） out of the 28 patient showed healing of coracoid process grafts，and the overall bone resorption rate was （18.4 ± 6.1）%. No patients had glenohumeral joint osteoarthritis. Conclusion:Arthroscopic Bristow procedure using suture-button fixation for treatment of recurrent anterior shoulder instability has advantages of a low rate of postoperative complications and a high union rate，indicating an effective and safe surgical procedure.

Multicellular network analysis is a method for topological properties analysis of cells. The functions of organs are determined by their inner cells. The arrangement of cells within organs endows higher-order functionality through a structure-function relationship, though the organizational properties of these multicellular configurations remain poorly understood. Multicellular network analysis with multicellular models established by 3D scanning of plants, will further discover the plant development mechanism, and provide clues for synthesizing plant multicellular systems. In this paper, we review the development of multicellular models, summarize the process of multicellular network analysis, and describe the development and application of multicellular network analysis in plants. In addition, this review also provides perspective on future development of plant multicellular network analysis.
