Objective To study the clinicopathological characteristics of complicated Kaposi's sarcoma after renal transplantation.Methods Five cases of complicated Kaposi's sarcoma after kidney transplantation were studied by histopathological immunohistochemical and ultrastructural observations.Results Of the 5 Kaposi's sarcoma patients,2 had multiple amaranthine dermal plaques starting on the legs,one had lymph node hypertrophy all over the body,and others had inguinal lymph node and adenoid hypertrophy. Histopathologically,these angiomatous lesions had characteristic areas of spindle cells within which erythrocytes were enmeshed.Admixed in these lesions were hyaline bodies and hemosider-laden,phagocytic cells.Immunohistochemical and ultrastructural studies revealed that this tumor was derived from vasofomative mesenchyme with multipotential capabilities.It was found that the epithelia and spindle cells were positive for Vimentin,CD-31,CD-34 and Ⅷ-RAg.Conclusion Complicated Kaposi's sarcoma after kidney transplantation can be diagnosed by combination of clinical manifestations and histopathological examinations with immunohistochemical and ultrastructural observations.

OBJECTIVE To analyze the reasons of misdiagnosis and surgical complications of primary lymphoma of thyroid gland(PLT). METHODS The clinical data of 10 patients with PLT in our hospital from 1992 to 2006 were retrospectively analyzed. RESULTS All of 10 patients were misdiagnosed,the major surgical complication was hoarseness. CONCLUSION The misdiagnosis of PLT is often encountered. Mastering the clinical features,using fine-needle biopsy,rapid biopsy combining immunocytochemical method can diagnose the primary lymphoma of thyroid gland.

Lipopeptides produced by Bacillus subtilis JA antagonized a broad spectrum of fungal pathogens. Crude lipopeptides were extracted with methanol from the precipitate which was obtained by adding 6 mol/L HCl to the cell-free culture broth.The crude extract was run on Diamonsil C_(18)column(5?m,250 mm?4.6 mm) in reverse phase HPLC system to purify the lipopeptides.Inhibitory ability and IC_(50)values of lipopeptides towards various microorganisms were determined by agar diffusion method.The results showed lipopeptides exhibited strong inhibitory activity against some important plant pathogenic fungi,including R.solani and F.oxysporum.The ability of B.subtilis JA to antagonize against the growth of the post-harvest pathogen -B,cinerea was tested in vitro.Spore germination of B.cinerea was strongly inhibited in the presence of JA cell suspension.Furthermore,B.subtilis JA can produce antifungal volatiles which strongly inhibited the spore germination and mycelial growth of B.cinerea.As a biocontrol agent,the synergic effect of lipopeptides and volatiles may play a major role in controlling the pathogens by B.subtilis JA.

The purpose and meaning of epidemiology curriculum,the current problems existing in the teaching and teaching reforms for different specialties were discussed.

Objective To reveal evolution characteristics and antigenic epitope variabilities of hemagglutinin (HA) gene of H3N2 viruses in Guangdong during 2014-2015.Methods The HA gene nucleotide sequence of influenza H3N2 virus isolated during 2014-2015 in Guangdong Province was selected by spatial-temporal distribution.The HA gene nucleotide sequences were compared with global HA genes downloaded from GenBank and GISAID and the gene nucleotide mutations were analyzed.The phylogenetic tree and the entropy chart were conducted.Results Compared with HA gene of vaccine strain A/Texas/50/2012,the substitutions of 25 amino acid sites occurred in the HA gene of the 17 Guangdong strains during 2014 to 2015.The epitope A,B,D and E of the HA1 gene developed mutations,which involved 11 amino acid sites.One glycosylation site deletion occurred in A/Guangdong/ 55/2015 in virtue of the N38K site mutation.The high mutation site was at 175 with entropy value of 1.16.The 363 site might be the positive selection while the 368 and 425 sites might be the negative selection sites by comprehensive evaluation of the screening results of the single likelihood ancestor countincy (SLAC),fixed effects likelihood (FEL) and internal fixed-effects likelihood (IFEL) model.Conclusions The mutations emerge in the epitopes A,B,D and E of HA gene of the Guangdong H3N2 stains.Evolution at 363 site is positive selection while those at 368 and 425 sites are negative selection.The mutation accumulation might lead to the epidemic of influenza H3N2.

Objective To make students at different levels not only learn theoretical knowledge of acupuncture-moxibustion manipulation skills but also achieve full operating training, strengthen the combination of theory and practice and improve the teaching quality of clinical disciplines by applyingmultimedia-subject participationteaching method to acupuncture-moxibustion manipulation techniques in the experimental teaching of acupuncture and moxibustion. Method The students were randomized, according to grade, into experiment (n=114) and control (n=115) groups. The teaching content was the same in the two groups. The experiment group received multimedia-subject participationteaching method. After the multimedia teaching, the students did an independent demonstration and made a self-evaluation, the teachers made a comment and the students did independent practice again in groups. The control group received conventional theory teaching and did practice under demonstration in the experimental lesson. The examination and questionnaire were used as assessment indicators to evaluate the effect ofmultimedia-subject participationteaching method applied to acupuncture-moxibustion technique teaching. Result Statistical analysis was made using the SPSS11.5 statistical software package. The independent samples t-test is used for a between-groups comparison. The statistical result showed that satisfaction was 100%in the experiment group and 75.7%in the control group;there was a statistically significant difference between the two groups (P<0.05). Conclusion Multimedia-subject participationteaching method is an innovation in acupuncture-moxibustion technique teaching and helps the students to better master acupuncture-moxibustion manipulation skills. Mastery of theoretical knowledge before real practice is the key to proficient manipulation. The combination of the two in classroom teaching yields twice the result with half the effort. Carrying out multimedia-subject participation teaching method will help to further deepen the teaching reform and to improve the level and quality of“Acupuncture and Moxibustion”teaching.

The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).
