Objective To explore the application value of CT perfusion imaging for predicting the tiny lymph nodes metastasis and micrometastasis of squamous cell carcinoma in cervix after neoadjuvant chemotherapy.Methods The clinical data and CT perfusion parameters of 46 patients with cervical squamous cell carcinoma who underwent neoadjuvant chemotherapy followed by surgery were enrolled in the study.Based on the surgical pathology findings and short-term follow up,the cases were divided into without tiny lymph nodes metastasis (short axle diameter of lymph nodes＜10 mm) group (n=32) and with tiny lymph nodes metastasis group (n=14).All perfusion data were analyzed retrospectively and the diagnostic value were investigated.Results Blood flow (BF),blood volume (BV) and the maximum diameter of tumor per-chemotherapy in with tiny lymph nodes metastasis group were higher than those in without tiny lymph nodes metastasis group (all P＜0.05).The differences of the maximum diameter of tumor after chemotherapy,permeability,time to peak (TTP) between two groups were not statistically significant (all P＞0.05).Multivariate Logistic regression analysis showed BF and the maximum diameter of tumor per-chemotherapy were independent predictors of the tiny lymph nodes metastasis in cervix after neoadjuvant chemotherapy.ROC showed BF (AUC=0.86,P＜0.001,95％CI [0.75,0.96]) had higher predictive value than maximum diameter of tumor per-chemotherapy (AUC=0.70,P=0.02,95 ％ CI [0.54,0.88]).Conclusion CT perfusion imaging shows the significant predictive value for the tiny lymph nodes metastasis of squamous cell carcinoma in cervix after neoadjuvant chemotherapy.

Objective To understand the influencing factors of the post competency of health technical personnel in township hospitals in a prov-ince,so as to provide scientific reference for improving health professionals'post competency. Methods Using stratified cluster random sam-pling,1242 health professionals from township health centers and village clinics of 14 cities were extracted and then surveyed with questionnaire. Results The average score of the respondents'post competency was 3.43,which meant they could afford most of the work. Multiple linear re-gression analysis showed that the main influencing factors of the professionals'post competency included gender,age,specialty,and training. The female,senior,nursing and health-care professionals with training exhibited a better post competency. Conclusion To realize the further develop-ment of professionals'post competency,medical students should not only be early clinical and more clinical,but also actively participate in the training and continue the education after entering the clinic. On the other hand ,the government should define the function orientation of the town-ship healthy centers and explore human resource management mode based on the post competency.

Objective To investigate the difference of colon length between patients with intractable constipation and normal peo-ple.Methods 40 patients with intractable constipation and 35 cases of normal control group received air enema CT scan,post-pro-cessing techniques-curved planar reformation and volume rendering were used to measure the length of colon.Results Colon length of normal people and constipation patients were (1 230±33)mm and (1 605±47)mm,respectively.There was significant difference between normal people and constipation patients (t=163,P=0.015).Conclusion CT air enema technique can be used to measure the length of colon obj ectively for diagnosing and treating redundant colon.

Objective To determine the effect of bacille Calmette-Guerin-polysaccharide nucleic acid (BCG/PSN)on 2,4-dinitrochlorobenzene(DNCB)-induced atopic dermatitis-like skin lesions in Nc/Nga mice.Methods Fifteen mice were randomly and equally classified into 3 groups,i.e.,control group receiving topical acetone on foot pad and abdomen and intraperitoneal injection of physiological saline,model group receiving topical 5% DNCB solution and intraperitoneal injection of physiological saline,treatment group receiving 5% DNCB solution and intraperitoneal iniection of BCG/PSN,and all drugs were used every other day for 7 weeks.Further more,0.1% DNCB was topically applied on the ear and neck of Nc/Nga mice once a week from week 2 to week 7.The effects of BCG/PSN were evaluated by ear thickness,skin histopathology and immunological parameters.Results Repeated application of DNCB caused the development of eczematous dermatitis in mice.Mice in model group chnieally manifested skin dryness,erythema,edema and erosion with histopathological changes including dermal and epidermal thickening,hyperkeratosis,and inflammatory infiltration.The serum levels of IL-4 and IrE in model group were significantly higher than those in control group[(174.72±12.64)μg/L vs (17.32±3.56)μg/L,(91.49±6.32)ng/L vs (83.95±6.63)ng/L,both P<0.05].Increased serum IL-12 and IFN-γ and decreased serum IgE were observed in treatment group compared with the model group[(122.10±4.64)ng/L vs (20.14±6.15)ng/L(73.89±2.39)ng/L vs (51.53±3.45)ng/L, (84.27±9.35)μg/L vs (174.72±12.64)μg/L, all P<0.05].Conclusion BCG/PSN might be beneficial for the treatment of atopie dermatitis-like skin lesions in Nc/Nga mice by enhancing the secretion of IL-12 and IFN-γ and suppressing the synthesis of IgE.

Objective To observe endothelial cells secreting and expressing nitric oxide by using red laser irradiation ( RLI) on cultured endothelial cells. Methods Cultured endothelial cells were irradiated with a red laser for 10, 20, and 30 minutes, respectively, and the concentration of nitric oxide in the cell supernatant was measured after 15 min,30 min.1 h,3 h and 6 h. In addition, the expression of inducible nitric oxide synthetase (iNOS) and endotlielial nitric oxide synthetase (eNOS) was measured through immunohistochemical staining. Results Compared with that in the control group, the expression of eNOS by the endothelial cells and the concentration of NO were stimulated by 2 mW RLI for 10 min, 20 min and 30 min, and reached a peak at 1 h, then declined gradually. The expression of iNOS, however, showed no significant difference. Conclusion RLI can increase NO concentrations in endothelial cells by stimulating the expression of eNOS rather than iNOS.

Objective To investigate the expressions and mutual relationship of Galectin-3 andβ-catenin in endome?triosis (EM). Methods Immunohistochemistry was used to detect expression levels of Galectin-3 andβ-catenin and their mutual relationship in expression was also examined. Samples were collected from ectopic endometrium of patients with en?dometriosis (ectopic endometrium group, n=34), eutopic endometrium of patients with endometriosis (eutopic endometrium group, n=34) and normal endometrium from people without endometriosis (control group, n=30). Results The expressions of Galectin-3 were seen in 88.2%, 85.3%, 50.0%of cases in ectopic endometrium group, eutopic endometrium group and control group respectively. On the other hand, the expression ofβ-catenin were seen in 55.9%, 52.9%, 26.7%of cases in ecto?pic endometrium group, eutopic endometrium group and control group respectively. In EMs patients, the expression of Galec?tin-3 andβ-catenin were significantly higher in ectopic endometrium and eutopic endometrium than those in normal endome?trium group(P<0.05). Expression of Galectin-3 was positive correlated with expression ofβ-catenin(rs=0.512, 0.428, P<0.01). Conclusion Galectin-3 andβ-catenin may play important roles synergistically in the pathogenesis of endometriosis.

Objective To assess the technical efficiency and subsystem technical efficiency of the healthcare institutions in China,including that of management system and medical system.Methods Panel data of 31 provinces' healthcare institutions were selected,and Network DEA was adopted to assess such input indicators as managerial staff and health technical personnel,and such output indicators as medical revenue and number of medical visits.Results The technical efficiency of healthcare institutions is as lower as an efficiency mean of 0.853 in five year.Provinces of Zhejiang,Shandong,Henan,Guangdong and Tibet have maintained a higher level.The healthcare system breaks down into two independent subsystems of the management subsystem and medical subsystem.The mean of the former one is 0.937,higher than 0.783 of the latter.The number of medical revenue and that of patients in the non-effective provinces were relatively inadequate.Conclusions Healthcare resources allocation in China needs to be optimized.It is imperative to adjust the input-output ratio,improve medical service quality via scientific management.
