Cervical cancer is one of the most common and deadliest cancers in females worldwide. Despite the treatment methods of surgery, radiotherapy and chemotherapy are maturing, the prognosis of patients with recurrent, advanced or metastatic cervical cancer remains poor. Molecular targeted therapy provides new hope for these patients. This review focuses on the advances in agents targeting vascular endothelial growth factor pathway, epidermal growth factor receptor, mammalian target of rapamycin, histone deacetylases and cyclooxygenase-2 in cervical cancer.

Objective To study spiral CT features and pathological basis of nodular goiter ,so that to improve the diagnostic accuracy of nodular goiter.Methods CT findings in 34 patients with nodular goiter confirmed by pathology were retrospectively analyzed and compared with pathological findings. Results Thyroid density in the patients with NG was lower than that in the normal. There was no statistically significant difference in the density between single and multi-NG. Most lesions(28/34) were multiple, round or oval, with different size and smooth edges. The density of majority lesions was lower than nearby normal tissue. Most lesions (27/34) were uniform in density. Central necrosis(5/34)often appeared in the bigger lesions(diameter＞3.0 cm). The CT value of the lesions was increased (47.1±42.2) HU after enhancement,but lower than surrounding thyroid tissue. Calcifications in the lesions(6/34)were puncticular,plaque or crustiform. Single or multiple cystic-solid or solid nodules could be seen in pathology, without a continuous capsule in the majority. Some patients (5/13) with single NG shown on imaging study were multi-NG in the pathology. Three cases of diffuse NG showed by CT were malignant in pathology. Conclusion There are certain characteristics for NG on spiral CT. Comprehensive evaluation may improve the accuracy of CT diagnosis.

Objective To investigate whether antiseptic central venous catheters (CVC) modified with chlorhexidine acetate and silver sulfadiazine can be beneficial in reducing bacterial colonization and catheter-related infection. Methods Prospective controlled non-blinded randomized clinical trial was conducted. Seventy adult inpatients with CVC from intensive care unit of General Hospital of Chinese People's Armed Police Force during June 2007-June 2009 were enrolled. Their baseline characteristics, APACHE Ⅱ score and therapeutic interventions were comparable. Patients were randomly received either an antiseptic CVC ( antiseptic group, n = 28) or a standard two-lumen CVC ( control group, n = 42 ). Microbiological evaluation was done after CVC removal. A catheter bacterial colonization ( CBC) was considered if bacterial growth of > 15 CFU was found by semi-quantitative roll-plate technique from a proximal or distal catheter segment. A catheter-related infection ( CRI) was defined as a colonized catheter with local signs of inflammation. A catheter-related bloodstream infection ( CR-BSI) was defined as a colonized catheter with isolation of the same organism from the patient' s blood with accompanying clinical signs of infection. SPSS 11.5 software was used for statistical analysis. Kaplan Meier curve was used to evaluate the association between CVC retention time and bacterial colonization or infection, and Log-rank test was performed to compare between the groups. Results CVC was removed from 3.6% (1/28) patients of antiseptic group and 21.4% (9/42) patients of control group because of infection (x2 = 5. 143, P <0. 05). Colonization of CVC was observed in 7. 1% (2/28) patients from antiseptic group and 35. 7% ( 15/42) from control group (x2 =7.458, P<0.01). CBC or CRI was not observed in antiseptic group until day 19, while CRI occurred at day 6 in the control group. CVC colonization and infection were developed in 31.4% and 14. 3% patients of antiseptic group during day 14-day 28 respectively, while the rates in the control group were 90% and 70% ( u = 27.5 and 14.31, P < 0.01). Conclusions Antiseptic CVC modified with chlorhexidine acetate and silver sulfadiazine can significantly lower the risks of CBC and CRI. But more than 50% patients would develop infection when colonization occured, no matter patients receive standard or antiseptic CVC. After CVCs have been inserted for > 2 weeks, the colonization and infection will increase significantly in both standard or antiseptic CVC, so to shorten the insertion time is an effective measure to decrease the CVC-related infection.

Objective The purpose of this study was to edit and psychometrically equate a set of Mandarin bisyllabic word lists. Methods 964 bisyllabjc words were recorded by male talker of standard Mandarin,352 words were selected to compose 10 lists. Percentage of correct word recognition was measured for each word at four intensity levels using 20 normal hearing subjects. The order of the presentation of the lists was randomized for each subject. U-sing Statistica7.0 Performance-Intensity function for each word was plotted,slopes and thresholds of them were calculated. 242 words were chosen after that, The thresholds and slopes of these words were in Guassian distribution. These words were ligitally adjusted and included in six Mandarin bisyllabic word lists of 40 words each. Two of them were for practice, four of them for test. 36 subjects with normal hearing served in our equivalent test. The orders of the presentation of the lists were randomized far each subject and results were expressed as thresholds. Results Two-factor ANO-VA was used to compare the thresholds of the 4 lists, F=1.978,P = 0.209. Conclusion These lists were considered to be primarily equivalent with each other.

Increasing cerebral blood flow in ischemic penumbra helps to promote neurological function recovery.Fibroblast growth factor is closely associated with angiogenesis after stroke;it may improve cerebral blood flow in ischemia penumbra,and thus contributes to neurological function recovery.Its application will become a novel approach in the treatment of ischemic stroke.

Objective To compare skin barrier function among patients with facial acne,subacute eczema,melasma and solar dermatitis.Methods Three hundred patients,including 80 patients with facial acne,60 subacute facial eczema,80 facial melasma and 60 facial solar dermatitis,as well as 60 healthy controls were recruited in this study.Skin sebum content and transepidermal water loss (TEWL) were measured by a sebmeter and Tewameter TM 210 (Courage and Khazaka,Germany),respectively.Stratum comeum hydration was measured with a Scalar Moisture Checker (Scalar Corporation,Japan).Statistical analysis was carried out using analysis of variance and t test.Results Compared with the healthy controls,patients with facial acne showed increased skin sebum content and TEWL value but decreased stratum corneum hydration (all P ＜ 0.01),and patients with subacute eczema,solar dermatitis and melasma displayed lower sebum content and stratum corneum hydration but higher TEWL value (all P ＜ 0.01).Skin sebum content was significantly higher in patients with facial acne than in patients with subacute eczema,solar dermatitis and melasma ((184.65 ± 83.07) vs.(21.86 ± 18.94),(25.10 ±14.22) and (36.05 ± 32.84) μg/cm2,all P ＜ 0.01),but was similar between the patients with subacute eczema,solar dermatitis and melasma (P ＞ 0.05).In terms of stratum corneum hydration,patients with subacute eczema and solar dermatitis were statistically lower than those with acne and melasma (18.66％ ± 7.85％ and 20.91％ ± 8.05％ vs.24.32％ ± 8.16％ and 28.02％ ± 4.67％,all P ＜ 0.01),patients with facial subacute eczema were similar to those with solar dermatitis (P ＞ 0.05),and patients with facial acne were statistically lower than those with melasma (P ＜0.01).TEWL value was significantly higher in patients with melasma than in patients with acne,solar dermatitis and subacute eczema ((13.80 ± 4.t 3) vs.(20.86 ± 8.78),(22.85 ± 9.84) and (22.48 ± 10.37) μg/m2 h,all P ＜ 0.01),but similar between patients with acne,solar dermatitis and subacute eczema (P ＞ 0.05).Conclusions Skin barrier function is somewhat impaired in patients with facial acne,subacute eczema,melasma and solar dermatitis.Therefore,to recover skin barrier function may facilitate the treatment of these diseases.
