Since 1974, 39 cases, after thumb reconstruction by means of free transplantation of second toe, haveundergone functional training in the therapeutic gymnasium of Huaskan Hospital. Functional training consists of using intermittent traction with indigenous equipmints to moblize the thumb joints and using resistanceexercises with small rubber balls and wooden framed net of rubber bends to strengthen the thumb musclesThe training was carried out three sessions a week for a total of 18--219 sessions, averaging 49. 5 sessions. The distribution of cases in classes of basic function of the thumb was as follows: Before training: Good, 0; fair, 11; poor, 28; After training: Good, 2; fair. 32; poor, 5. Practical activities of the hand, such as selfserving. writing, sewing and using common tools were perfor-med satisfactorily when basic function of the thumb reached "good" or "fair" class.

Objective To evaluate the roles of signal transducer and activator of transcription 3(STAT3) played in delayed xenograft rejection.Method Mice-to-rats cardiac xenograft model was established and recipients were administrated by inhibitor of phosphorylation of STAT3,5,15-Diphenylporphyrin(DPP),and immunosuppressive agent,ciclosporin A (CsA) alone or both.The survival of graft was analyzed.Immunohistochemistry and immunoblotting were utilized to detect the phosphorylated STAT3 (p-STAT3),and real-time polymerase chain reaction was used to assess STAT3-targeted genes in grafts.Result The expression of p-STAT3 was increased significantly with the prolonged survival in grafts (P < 0.05).Administration of DPP and CsA both significantly prolonged survival of the grafts (P<0.05),and decreased the expressions of STAT3-targeted genes including Bcl-xl,Bcl-2,Cyclin D1,C-myc and VEGF (P<0.05).DPP and CsA exerted the synergistic effects.Conclusion STAT3,which is persistently activated in cardiac xenografts,probably up-regulates downstream genes to promote proliferation and to inhibit apoptosis of endothelial cells,leading to the activation of endothelial cells and delayed xenograft rejection.

A total of 101 honey samples that originated from 20 different unifloral honey and other multifloral honey samples were collected from China.FT-NIR spectrometer were applied to determinate the content of fructose and glucose of honey with two different modes: transflectance (800-2500 nm, 2 mm optical path length) and transmittance (800-1370 nm, 20 mm optical path length).It was found that the prediction accuracy of fructose and glucose had significant difference with the two modes.In order to analyze the reason of this difference, support vector machine (SVM) was used to analyze the non-linear information, and genetic algorithm (GA) was used to analyze the characteristic wavelengths.The result indicated that the detection difference of fructose and glucose was originated from their different characteristic wavelengths.Through the optimization of detection method, it was found that for the determination of glucose, short wavelength and long optical path length should be used, on the other side, the whole wavelength region and short wavelength, with selecting the characteristic wavelength to avoid the disturb of water can also be used.For the determination of fructose, whole wavelength region and short optical path length should be used.Linear regression methods such as PLSR could obtain good results, and non-linear methods such as SVM did not improve the model performance.

Objective:To prepare monoclonal antibodies specifically against an immunogenic fragment in ectodomain of prostate-specific membrane antigen ( PSMA ).Methods: An polypeptide immunogenic fragment in the ectodomain of PSMA was predicted by biological information technology,and then it was expressed prokaryotically.BALB/c mice were immunized with the prokar-ytically expressed recombinant polypeptide antigen,to prepare the monoclonal antibodies specifically against an immunogenic fragment in ectodomain of PSMA by hybridoma technology,purification of monoclonal antibody by affinity chromatography,characterization of the monoclonal antibodies by Western blot.The radioimmunoimaging in prostate cancer model was performed by using the labeled McAb.Results:Throught the software analysis,we got the antigen fragment in the ectodomain of PSMA containing 310aa sequences higher specificity, artificially synthesized gene sequence of the region, and constructed a prokaryotic expression vector pET-32a-r-ectodomain-PSMA,by prokaryotic expression we obtained the 50 kD target antigen,after hybridization,the three positive hybridoma cell lines (5E6,4A5 and 4D7) were selected by ELISA using target antigen,the isotypes of 5E6 and 4A5 were IgG2a,the isotypes of 4D7 were IgG1,the titer of three monoclonal antibodies was above 1∶256 000.Western blot results showed that the prepared monoclonal anti-bodies could binding specifically to the antigen in the ectodomain of PSMA.Radioimmunoimaging in prostate cancer animal model results further confirm that the prepared monoclonal antibodies could combinate with the antigen in the ectodomain of PSMA in the animal body, and make the tumor imaging.Conclusion: The prepared monoclonal antibodies can specifically recognizes the PSMA antigen,which laid the foundation for the immunodiagnosis and immunotherapy of prostate cancer.

ObjectiveTo study the anatomical abnormalities of basal ganglia and research their influence on depression status in patients with post stroke depression (PSD)by diffusion tensor imaging (DTI) of MRI.MethodsPatients with basal ganglia infarction were recruited,and divided into groups of PSD and non depression control group by Hamilton Depression Rating Scale (HAMD) assessment. All the patients were evaluated with National Institute of Health Stroke Scale ( NIHSS). And the patients were checked by DTI sequence.Fractional anisotropy (FA),average diffusion coefficient (ADC) values and the number of nerve fiber were measured in bilateral caudatum,pallidum,putamen and thalamus.ResultsThe score of NIHSS (6.29 ± 3.45 ) was significantly higher in PSD group than that in non-depression group (3.95 ± 1.90 ;t =2.219,P =0.036). No significant difference was found between the two groups for the DTI data of the basal ganglia nuclei ( t =0.056-1.618,all P > 0.05 ). Compared with contralateral construction (0.40 ± 0.02 ),the FA value decreased in the left putamen ( 0.37 ± 0.03 ) in the PSD group ( t =2.243,P =0.045 ).By Spearman correlations analysis,the HAMD score was positively correlated with NIHSS score ( r =0.464,P =0.017 ),and negatively correlated with the FA values of left pallidum (r=-0.563,P=0.005),right pallidum (r=-0.416,P=0.035) and left putamen (r =-0.428,P =0.029).Conclusions The occurrence of PSD was associated with neurological functional deficit following basal ganglia infarction.The depression level was correlated with the increasing of NIHSS score,the reductions in bilateral pallidum and left putamen FA values.This research contributes to evaluation of the PSD status in patients with basal ganglia infarction.
9.Interpretation of Guide to the Quality and Safety of Organs for Transplantation (6th edition): biosafety early warning
Organ Transplantation 2020;11(1):98-
With the rapid development of organ donation and transplantation, it becomes increasingly important to improve the management system and ensure the quality and safety of organs for transplantation. Guide to the Quality and Safety of Organs for Transplantation (6th Edition) by European Committee provides the definitions of severe adverse reactions and severe adverse events in the perspective of biosafety early warning, delivers management and reporting processes, and encourages medical staff involved in organ transplantation to identify the adverse reactions and adverse events as soon as possible, and to carry out investigation, assessment and feedback. At the same time, it also systematically illustrates the warning and monitoring of organ transplantation risk, which is worthy of application in clinical study and practice.
