Objective To discuss the methods and effects of replantation to treat complex thumb severance. Methods 56 cases of complex thumb severance combined with soft tissue defects were treated with simple vessel transplantation, veno flap transplantation, dorsal index digital island flap transplantation, digital artery transfer, transfer of radial index digital artery pedicled island flap, or veno arteriolization. The soft defects were repaired by the transfer of extensor index finger tendon and superficial ring finger flexor tendon. Results 50 cases survived and 6 cases failed, with the survival rate being 89%. 42 cases were followed up for 5 to 25 months. The function of the treated thumbs was assessed as excellent in 10, good in 25 and bad in 7. The excellent and good rate was 83%. Conclusion Complex thumb severance can be treated by unconventional replantation so as to achieve good effects.

Objective To estimate the influence of abnormal glucose metabolism during pregnancy and family history of cardio-cerebrovascular disease and/or diabetes on umbilical C-peptide concentrations. Methods Chesed 85 pregnant women who had prenatal examination and their newborns as the subjects. Thirty-six newborns of mothers with gestational diabetes mellitus, impaired glucose tolerance or diabetes mellitus with pregnancy and 49 newborns of mothers with normal glucose tolerance were randomly chosed as the control group. All newborns were also classified according to whether their maternal grandparents had history of diabetes and/or cardio-cerebrovaacular disease. Therefore, there were four groups in this study: 25 newborns in group A were of diabetic mothers and positive family history, 11 newborns in group B were of diabetic mothers but negative family history, 9 newborns in group C were of mothers with normal glucose tolerance but positive family history, 40 newborns in group D were of mothers with normal glucose tolerance and negative family history. The blood samples of umbilical veins were collected at the time of delivery. Umbilical C-peptide levels of the four groups were measured by radioimmunonssay. Results The umbilical C-peptide concentrations of newborns in group A, B, C, D were (2.22±1.52), (1.44±0.63), (1.13± 0.34), (1.31±0.69) μg/L respectively, the umbilical C-peptide concentrations of newborns in group A were elevated compared to those of other three groups (F=5.11, P=0.003), and there were no significant differences in C-peptide levels of newborns between the three groups (group B vs C P=0.499, group B vs D P=0.694, group C vs D P=0.642). Conclusion Special attention should be given to newborns of diabetic mothers and whose maternal grandparents have history of diabetes and/or cardio-cerebrovascular disease.

OBJECTIVE:To establish a method for the simultaneous determination of paeoniflorin,baicalin and imperatorin in Urticaria pill.

Forkhead box M1 (FOXM1),one member of the Forkhead family,plays an important role in tumor development,invasion,metastasis and angiogenesis by regulating the expression of tumor related genes.Moreover,The specific mechanism of FOXM1 is not fully understood in the development of tumors.Currently,the study of anticancer drugs targeting FOXM1 is in the initial stage.Exploring the mechanism of FOXM1 in carcinogenesis and the development of drugs targeting FOXM1 and its downstream signaling pathways have broad clinical application prospects.

Objective To investigate the effect of Urinarykallid for different ages patients with acute cerebral infarction cases.Methods Ninety-five cases with acute cerebral infarction were divided into high age group(n=48) and middle age group(n=47).Patients in the two groups were both given the Urinarykallid therapy combined with routine treatment.After 1 courses of treatment(3 weeks),American National Institutes of Health Stroke Scale(NIHSS) were performed before and after the treatment.The adverse reactions occurred in the process of scoring were compared.Results The total effective rate in the high age group was 83.33％,lower than the middle age group(89.36％),but the difference was not statistically significant(P=0.391).The NIHSS scores of patients in the two group after treatment were both significantly reduced compared with that in before treatment (high age grou:(9.81±2.37) vs.(6.79± 0.82),middle age group:(9.75 ± 2.46) vs.(3.04±0.58;P=0.004,P=0.001).Meanwhile,the NIHSS in the middle age group decrease significantly than the high age group(P=0.000).No obvious adverse reactions occurred in both two groups,the treatment was proved with safe and reliable.Conclusion Urinarykallid treatment is showed with better therapy effect on acute cerebral infarction patients with different age,and it is safety with improving patients NIHSS score level.Meanwhile,the better efficacy is showed in patients with lower age.

Objective To establish a rapid and sensitive chemiluminescence immunoassay for detecting squamous cell carcinoma antigen (SCCA)in human serum.Methods Fluorescein isothiocyanate (FITC)and N-(aminobutyl)-N-(ethylisoluminol)(ABEI) were used to label two different monoclonal antibodies of anti-SCCA.SCCA in serum combined with labeled antibodies and formed a sandwiched immunoreaction.After adding the substrate solution,the relative light unit of ABEI was measured.Magnetic particles coated with anti-FITC antibody were used as solid separation carrier.Results The results demonstrated that the method was linear to 22 ng/mL with a detection limit of 0.025 ng/mL.The coefficient of variation (CV)was less than 6% and 7% for intra-assay and inter-assay precision,respectively.Compared with the commercial kit,the proposed method showed a correlation of 0.990 1.Conclu-sion chemiluminescence immunoassay based on magnetic particles displays acceptable performance for quantification of SCCA and is appropriate for use in clinical diagnosis.

Objective: To investigate the anti-inflammatory, especially the inhibitory effects of TZT-5, an active component from the leaves of Triterygium wilfordii, on the rheumatoid arthritis of rats and to explore its pharmacodynamic effect using an arthritic model of rats. Methods: The ear swelling model induced by croton oil in mice, paw edema model induced by carrageenin in rats, chicken collagen II (CCII)-induced arthritic model, and adjuvant-induced arthritic (AIA) model in rats were established, respectively. The in vivo anti-inflammatory and inhibitory effects of TZT-5 on the rheumatoid arthritis of rats were observed. Results: TZT-5 could alleviate the symptoms of the above four inflammation animal models, ameliorate the infiltration of inflammatory cells in synovium, and inhibit the proliferation of synovial cells in both CCII-induced arthritic models and AIA models of rats. Conclusion: TZT-5 has the ideal anti-inflammatory effects on CCII-induced arthritic model and AIA model of rats and it is a candidate as a new anti-rheumatoid arthritis drug.

Tropical medicine is defined by an association with geographic location, and it is a branch of medicine integrating preclinical medicine, clinical medicine and preventive medicine and investigating the diagnosis, treatment and prevention of diseases of tropical and subtropical zones. Military tropical medicine is a new interdiscipline based on tropical medicine and military medicine. With the improvement of health condition and the development of global economy, some tropical infectious diseases have been gradually controlled. However, factors such as increasingly frequent international communication and extreme changes in global climate induced by overproduction activity of human are leading to a redistribution of infectious diseases, which inevitably has impact on military strategies and tactics. This article reviews the past and prospect of military tropical medicine.

Epidemic diseases often occur following natural disasters, such as earthquakes. The most commonly seen epidemics after an earthquake include: enteric diseases (dysentery, typoid and paratypoid fever, cholera, hand foot-mouth disease, hepatitis A, hepatitis E, etc), arthropod-borne infectious diseases (malaria, Kala-Azar, Japanese encephalitis, etc), zoonosis (plague, hemorrhagic fever with renal syndrome, anthrax, etc), soil and epidemic water transmitted diseases (tetanus, gas gangrene, leptospirosis, etc), respiratory diseases (measles, rubella, influenza, etc), food-borne diseases (food poisoning caused by bacteria or bacterial toxin). This article reviews the controlling principles and measures for major infectious pathogens and epidemic diseases after earthquake.
