Objective To study leprosy epidemic level and its trends in Yancheng during 1949－ 1999. Methods Materials of 8 997 cases detected and leprosy control in Yancheng City were analyzed. Results Prevalence, incidence and detection rates of each county and city showed the trends which first rose then declined. And the district distribution showed a characteristic of“ high in the south and low in the north, more in the west and less in the east” .At the end of 1999,the mean prevalence of late 5 years was 0.5/100 000 with both detection and incidence rates of 0.08/100 000. Conclusion The leprosy endemicity has been controlled through 50 year control. It illustrates that in the futare the leprosy control must strengthen the health education, carry out classified guidance and improve the case－ finding efficacy.

Objective To investigate the relationship between lymphadenectomy and the prognosis of endometrioid adenocarcinoma.Methods Eighty-six cases of endometrioid adenocarcinoma patients who got a clear diagnosis and accepted system surgical treatment and had complete follow-up data were collected in this study.Fifty-eight cases routined lymphadenectomy (lymphadectomy group),and 28 cases didn't routine lymphadenectomy (without lymphadectomy group).The relationship between related pathological features and lympha node dissection state were evaluated by univariate analysis,and through survival analysis to understand the relationship between lymphadenectomy and the prognosis of endometrioid adenocarcinoma.Results The 3-years disease-specific survival rate (DSS) in lymphadectomy group and without lymphadectomy group were 82.1％ and 61.8％,which reached statistical significance (P =0.006).The 3-year DSS of FIGO Ⅰ A stage in lymphadectomy group and without lymphadectomy group were 93.8％ and 95.7％ (P=0.704),the 3-year DSS of FIGO Ⅰ B-Ⅳ stage in lymphadectomy group and without lymphadectomy group were 49.1％ and 35.4％,which reached statistical significance (P =0.044).Correlation analysis results showed that FIGO stage late (≥ Ⅰ B stage),higher tumor grade (G2-3 grade) were independent poor prognosis factors of 3-year DSS,and lymphadenectomy was an independent good prognosis factor.Conclusion Lymphadectomy can improve the prognosis of endometrioid adenocarcinoma patients who are FIGO Ⅰ B-Ⅳ stage,has therapeutic significance.

Objective To investigate the effect of continuous blood purification ( CBP) on the level of blood lactic acid and 6 h lactic clearance in the patients with severe sepsis. Methods 48 patients with severe sepsis were cho-sen in ICU, and they were randomly divided into two groups: control group ( n=20 ) and CBP group ( n=28 ) . Their arterial blood lactic acid level was tested on admission and was retested 6, 24, 48 and 72 h after treatment. The patients’6 h blood lactic clearance rate and the corresponding APACHEIIscore were calculated. The level of arterial blood lactic acid and the score of APACHE IIwere compared at different time. 6 h blood lactic clearance, the period of stay in ICU and the 28-days mortality were compared too. Results The level of lactic acid and the score of APACHE II after 24 h were lower in CBP group, and the period of stay in ICU was shorter in CBP group than that in control group at different time ( P<0.05 ) . 6 h blood lactic clearance was higher than that in control group (P<0.05). Moreover, the 28-days mortality had no significant difference in CBP group. Conclusion The CBP plays an important role in clearing the blood lactic acid and it can reduce the severity of the sepsis as well as shorten the period of stay in ICU.

The Back-Shu points of the five Zang-organs are a group of points where qi and blood pour into the back and lumbar regions. Acupuncture at these points has a wide indication scope. However, it’s reported that internal organs were punctured in some cases because of improper control of needling depth, angle, and intensity during acupuncture. We used perpendicular needling instead of conventional oblique needling during the acupuncture of the Back-Shu points of the five Zang-organs. We found that when patients were completely relaxed, acupoints were correctly selected, the needling depth, the way of holding the needle, and inserting methods were well controlled, perpendicular needling of the Back-Shu points of the five Zang-organs can produce stronger needling sensation, and it’s easier to operate, safer, and more effective compared to oblique needling.

Thirty-seven cases of brain glioma,confirmed by light microscopy and immuno-'histochemistry were studied with transmission electron microscopy.It was found that there were certain ultrastructural features for each type and each grade of glioma.In astrocytoma,there was certain amount of glial filaments in the tumor cells; Rosenthal fibers consisted of irregular osmiophilic masses surrounded with glial filaments,occasionally cytoplasmic annulate lamellae and intranuclear filaments could be seen,and the interstitial capillaries were characteristic.In typical oligodendroglioma,astrocytic processes containing glial filaments were quite present in different amounts.These findings suggest that observation on the ultrastructure of gliomas is of significance to establish the diagnosis,to assess the degree of differentiation,and to identify some rare structures which can reveal the essence of the tumor.In addition,ultrastructural observation is helpful for prognosis.

Environmental physiological method adopted, the ergonomic experiment is to seek the best parameter of the protective hood structural size, on which the structure design of the protective hood will be based, through the analysis of the organic relationship between the microenvironment of power air-purifying medical protective hood and the body's physiological characteristics. The changes of such indexes due to different air currents are analyzed as the oxygen, carbon dioxide, temperature and humidity in the microenvironment. The changes of testees' physiological parameters and their responses to psychological loads and body strengths are paid attention to. The results show the hood can meet the testees' demands with proper air current.

Objective To explore the TCM pathogenesis regularity of nonalcoholic fatty liver disease (NAFLD);To provide basis for clinical syndrome differentiation and treatment. Methods A cross-sectional study was used. The clinical observation form of NAFLD was used to collect the patient data. Factor analysis and singular value decomposition methods were used to study the internal factors of the four diagnostic characteristics. The differences between the various analytical methods were compared. Results Factor analysis used the α factor analysis method, the principal component method, and the image factor method. The results of α-factor analysis were the best. The first three factors had the highest explanatory rates of data, namely spleen-dampness factor, kidney deficiency factor and qi deficiency factor, which constituted the basic pathogenesis factor of NAFLD. The singular value decomposition method obtained 3 singular values, namely spleen and kidney qi deficiency, liver and kidney yin deficiency, and qi and yin deficiency, also highlighted the spleen and kidney deficiency in the pathogenesis of NAFLD. Conclusion Spleen-kidney deficiency plays an important role in the pathogenesis of NAFLD. Treatment based on deficiency for nonalcoholic fatty liver disease has great clinical significance.

ObjectiveTo investigate the relationship between syndrome differentiation types and the objective indexes of fatty liver.MethodsA cross-sectional study was adopted. Clinical observation table of fatty liver for TCM diagnostic performance was used to collect the data of patients and cluster analysis was adopted for syndrome differentiation. The difference of the objective indexes among different syndromes was studied.ResultsFatty liver showed more severity in spleen Qi deficiency and dampness group compared with heart and liver yin deficiency group(χ2=8.218,P=0.041). Patients in the spleen and stomach Qi deficiency group had less smoking history(χ2=8.416,P=0.038). Patients in the spleen Qi deficiency and dampness group had higher AST, TP, ALP and WHR indexes and lower Alb.ConclusionsDifferences of objective indexes in different fatty liver syndromes can be used for enriching syndrome differentiation contents, and provide the basis for microcosmic syndrome differentiation of fatty liver.

Objective To investigate the expression and clinical significance of MUC1,MUC2,MUC4 and MUC5AC in pancreatic ductal adenocarcinoma(PDA).Methods To analyze the expression profiles of MUC1,MUC2,MUC4 and MUC5AC in PDA(n=26),chronic pancreatitis(CP,n=4),normal pancreas(n=16)and intraductal papillary-mucinous neoplasm(IPMN)(n=2),solid-pseudo-papillary tumor of pancreas(SPT)(n=4),serous cystic neoplasm(SCN)(n=1)using immunohistochemistry.Results Positive staining with MUC1 Was exclusively found in normal pancreas and CP tissues(100%);the expression of MUC1,MUC4 and MUCSAC in PDA was 100%,88.5%(23/26)and 76.9%(20/26)in PDA tissue;MUC2 and MUC5AC were expressed in 2 samples of IPMN;none of the four mucins were expressed in Sfrr and SCN.There was no association between the expression of MUC4,MUC5AC and the clinicopathologic parameters in PDA(P＞0.05).Conclusions Multiple mucins were expressed in PDA.Measurement of the mucin profile including all 4 mueins(MUC1,MUC2,MUC4,and MUC5AC)may be helpful in the diagnosis and differential diagnosis of PDA.
