Objective To explore the expression of RET in cervical squamous carcinoma tissues and evaluate its relationship with cervical squamous carcinoma clinical pathological indexes and its prognostic value. Methods The expression and distribution of RET in normal cervical tissues ,CINⅠ,CINⅡ& CINⅢ and cervical squamous carcinomas tissues were detected by immunohistochemistry in wax blocks. Clinical data and follow-up data are integrated to analyze its relationship with clinical pathological factors and prognosis value. Results The positive rate of RET protein in cervical squamous carcinomas tissues is higher than in other tissues.The positive rate was related to FIGO stage and lymph node metastasis(P<0.05),and not related with the age of patients or the degree of tumor differentiation(P>0.05). The result of survival analysis with Kaplan-Meier method showed poorer disease-free survival time in the patients with high expression of RET (P < 0.05). Prognostic analysis of patients with cervical cancer through COX proportional hazard regression model suggested that RET expression was an independent prognostic factor. Conclusions RET has been involved in the progression ,FIGO stage and metastasis of cervical squamous cell carcinomas.

Purpose:To explore the clinical feature,and treatment of primary cervical lymphoma. Methods:Clinical data and follow-up survey data of 26 cases were retrospectively analyzed with SSPS software. Results:Primary cervical lymphoma could occur in any age group of women. The misdiagnosis rate was as high as 57.69% (15/26 case).Three of 26 patients died,the five years survival rate was 88.46%.Conclusions:Primary cervical lymphoma is rare,which was very often misdiagnosised. The treatment consisted of an combination of chemotherapy,operation and radiotherapy,which could improve curative results and reduce relapse.

Objective To evaluate the diagnostic value of 18F-FDG PET-CT in looking for tumor primary lesion with multiple bone metastasis.Methods 84 patients with suspected bone metastases were detected by routine imaging (X -ray,CT,MRI)in our hospital from May 2012 to September 2014 were selected,18F -FDG PET/CT were used to find the primary lesion.The final diagnosis were confirmed by tissue pathology or by clinical imaging follow -up.The diagnostic sensitivity,specificity and accuracy on tumor bone metastasis of 18F -FDG PET/CT were recorded.Results In 84 patients,primary tumor was found in 49 cases,of which 46 cases (54.8%)confirmed pri-mary tumor by operation or pathology,the other 3 cases were false positive;35 patients were diagnosed as non meta-static bone tumor by PET/CT,in which 34 cases were finally confirmed as non metastatic bone tumor by pathology and follow -up;accuracy,sensitivity,specificity of 18F -FDG PET/CT were 54.8%(46 /84),93.9% (46 /49)and 95.2%(80 /84);18 cases of lung cancer,9 cases of prostate cancer,7 cases of breast cancer,5 cases of lymphoma, 4 cases of renal cell carcinoma,2 cases of liver cancer,1 cases of Uterine sarcoma were included in 46 primary tumors.Conclusion 18F -FDG PET/CT has a higher specificity,accuracy as well as higher detection rate in search of multiple bone metastases,thus it is beneficial to the clinical therapy.

Objective To study the relation between the levels of protein C(PC),protein S(PS),antithrombin Ⅲ(AT-Ⅲ)with cerebral infarction.Methods 126 patients with cerebral infarction were divided into the groups according to the age,onset time and infarction area and contemporaneous 30 individuals with healthy physical examination were selected as the control group.The levels of PC,PS and AT-Ⅲ were detected.The relation between the change of these indicator levels with the age,onset time and infarction area was analyzed Results The levels of AT-Ⅲ,PC and PS in the acute stage youth group were lower than those in the acute stage middle age and elderly group with statistical differences between them (P <0.05).The level of the AT-Ⅲ,PC and PS in the acute stage group were lower than those in the recovery stage group and the control group,difference had statistical significance(P <0.05).The levels of AT-Ⅲ and PS in the recovery stage group were lower than those in the control group with statistical difference (P <0.05),but the level of PC had no statistical difference between the recovery stage group and the control group.The further study found that the level of AT-Ⅲ,PC and PS in the small infarction group,middle infarction group and large infarction group showed the gradually decreasing trend,the differences had statistical significance (P <0.05).Conclusion The decrease of AT-Ⅲ, PC and PS levels is the importan factor of cerebral infarction occurrence and is closely correlated with cerebral infarction ocurrence especially in the patients less than 45 years old.Observing the change of PC,PS and AT-Ⅲ levels has the important significance for judging the cerebral infarction progression.

Objective To study the influence of Chiamydia trachmatis (CT) and Ureaplasma ure-alyticum (UU) infection on pregnant outcome and neonates. Methods 562 pregnant women were ran-domly selected, their cervical secretion was collected and detected for CT and UU by culture method. Groups were divided according to the results. All of them were followed-up till delivery. Results The in-cidence of infection of group CT、group UU、group CT and UU were 22.1%、28.8% and 3.7%;Compared with negative group,the group with positive result of CT、UU、 CT and UU had significant higher incidence of preterm labor, premature rupture of membranes, low weight infant and neonates pneumonia. Conclusions The infection of CT、UU can result in adverse pregnant outcome, preterm labor, premature rupture of mem-branes, low weight infant and neonate pneumonia.

OBJECTIVE:To discuss rational use of injection in order to provide reference for rational use of injection in the clinic. METHODS:Drug use was analyzed in respect of route of administration,selection of solvent,compatibility of drugs, speed of intravenous administration,the concentration of mixture,etc. RESULTS&CONCLUSION:There are some mistakes in the application of injections,but some faults and adverse drug reactions (ADRs) can be warned early. By strengthening pharmaceutical monitoring,related faults and ADRs can be reduced to the minimum.

Objective To investigate the effects of dilute concentration and acting time of pronase on quality of gastroscopy.Methods A total of 448 patients were randomly divided into two groups : sodium bicarbonate group and pronase with sodium bicarbonate group.Pronase was diluted into 50 ml (400 U/ml)and 100 ml (200 U/ml) using sodium bicarbonate.The patients were pretreated by pronase of different concentrations 10 min, 20 min, 30 min, 60 min and 120 min before gastroscopy.Diluent of same quantity were taken by the control group.Visibility of gastroscopy, procedure times and positive rates of lesions were compared.Results Pretreatment of pronase significantly improved visibility of gastroscopy, raised positive rates of lesions, and reduced procedure times of gastroscopy, compared with the control group (each P ＜ 0.05).The visibility of gastroscopy were over 80％ 20,30, and 60 minutes before the examination with no significant difference(P ＞ 0.05).The visibility of gastroscopy decreased sharply 30 minutes after taking pronase, especially after 60 minutes.There was no significant difference in the quality of gastroscopy between the 200 U/ml and 400 U/ml group 20-60 minutes before gastroscopy (P =0.640).Conclusion Pronase (200 U/ml-400 U/ml) significantly improves visibility of gastroscopy, raises positive detection rates of lesions, and reduces procedure time of gastroscopy 20-60 minutes before pretreatment.

Objective To summarize the clinical characteristics and laboratory test results of children with Henoch - Schonlein purpura(HSP),and further to analyze the risk factors for HSP combined with cardiac damage. Methods The clinical and laboratory tests findings from 707 children diagnosed as HSP at Nanjing Children's Hospi-tal were retrospectively analyzed,who were recruited from November 2011 to December 2012. The possible risk factors for HSP with cardiac damage in children were recorded,including gender,age,predisposing causes,gastrointestinal symptoms,joint pain,kidney disorders,serum electrolytes,anti - streptolysin 〝O〝 test,erythrocyte sedimentation rate, and complement level were summarized. Chi - square test and Logistic regression were performed to analyze the risk fac-tors of cardiac damage in children with HSP. Results Among 707 cases,192(27. 2% )patients were combined with car-diac damage,115 male and 77 female,and the proportion of men to women was 1. 00: 0. 67;age ranged from 11 months to 15 years and 4 months(6 years and 5 months for median age),6 patients ﹤ 3 years old occupying 3. 1% ,103 patients≥3 - 7 years old occupying 53. 7% ,82 patients≥7 - 14 years old occupying 42. 7% ,1 patient≥14 years old occupying 0. 5% ,and the age of onset in preschool and school age. Electrocardiogram(ECG)abnormalities were found in 190 patients,the main manifestations including long Q - T interval,ST - T segment falling down and sinus bradycar-dia,and one or more items of abnormal myocardial enzymes existed in 24 cases;echocardiography was performed in 35 cases of children,but no abnormality was detected,no obvious symptoms such as flustered or chest tightness or precor-dial distress. Statistical analysis showed that gender,predisposing causes,mixed HSP,complement level were related to the incidence of cardiac damage in children with HSP(P ﹤ 0. 05). Furthermore binary Logistic regression identified that in male patients,the ratio of X1 vs OR ratio was 0. 654(95% CI 0. 462 - 0. 926,P ﹤ 0. 05),for predisposing causes,the ratio of X2 vs OR ratio was 2. 63(95% CI 1. 838 - 3. 765,P ﹤ 0. 001),for mixed HSP,the ratio of X3 vs OR ratio was 2. 452(95% CI 1. 301 - 4. 621,P ﹤ 0. 01),which were independent factors for cardiac damage in chil-dren with HSP. Conclusions ECG and/ or myocardial enzyme spectrum abnormalities are the main clinical ma-nifestations of cardiac damage in children with HSP. Male patients,predisposing causes of the respiratory tract infec-tion,mixed HSP and hypocomplementemia were high risk factors in the development of cardiac damage,which require special consideration clinically,and earlier ECG and myocardial enzymes examination,early diagnosis and treatment are necessary to avoid the occurrence of severe cases.

OBJECTIVE: To observe whether curcumin could inhibit the accumulation of the collagen IV and fibronectin in the glomeruli in nephrotoxi sera nephritis rats. METHODS: Seventy-two healthy male Sprague-Dawley rats were divided into three groups, with 24 animals in each group. For normal control group, normal saline (0.5 ml/d) was injected through intra-caudal-vein for two days, and at the same time normal saline (0.5 ml/kg) was also daily administered intraperitoneally. For nephrotoxic sera nephritis group, nephrotoxic sera (0.5 ml/d) was injected through the tail vein for two days and dimethyl sulfoxide (0.5 ml/kg) was given intraperitoneally daily. For curcumin group, nephrotoxic sera was injected as above and meanwhile curcumin (50 mg.kg(-1).d(-1)) was administered intraperitoneally every day. Six rats in each group were killed on the 3rd, 7th, 14th and 28th day. Their renal tissue was fixed in 10% formalin for examining the expression of collagen IV and fibronectin. RESULTS: Minimal staining of collagen IV and fibronectin was detected in the basement membrane of normal control rats glomeruli. In the nephrotoxic sera nephritis rats and curcumin treated nephrotoxic sera nephritis rats, the accumulation of collagen IV and fibronectin was increased progressively, with significant difference in the accumulation of collagen IV (P<0.01) between these two groups at the same time points, while the significant difference in fibronectin accumulation (P<0.05) appeared only after the 7th days. CONCLUSION: Curcumin can reduce the accumulation of collagen IV and fibronectin in the glomeruli. Hence we postulated that curcumin might have beneficial effect for retarding glomerulosclerosis.
