Objective To investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.

Objective To examine the relationship of coping style,psychological capital and vocational selection anxiety for female college graduates.Methods A sample of 330 female college graduates filled out measures for the simplified coping styles questionnaire (SCSQ),Psychological Capital Questionnaire (PCQ) and vocational selection anxiety Questionnaire(VSAQ).Results Correlation analysis showed that except the self-efficacy and positive coping style collected with concerns about job prospects was not significant (r=-0.08-0.05,P＞0.05),each dimensions of PCQ and SCSQ significantly correlated with the each dimensions of VSAQ (r=-0.44--0.13 or r=0.21-0.28,P＜0.01).Regression analysis showed that negative coping style,resilience,hope and positive coping style could directly predict vocational selection anxiety.Psychological capital were the mediators between positive coping styles and vocational selection anxiety.Conclusion Coping styles and psychological capital are closely related to the female college graduates' vocational selection anxiety,using appropriate coping styles and improving mental ability can effectively reduce vocational selection anxiety.

ObjectiveTo assessment the value of strain ratio(SR) in differentiating benign and malignant breast lesions of BI-RADS Ⅳ diagnosed by conventional ultrasound.MethodsElastosonography was performed on 64 patients with breast lesions of BI-RADS Ⅳ diagnosed by conventional ultrasound.SR (strainnormal neighboring tissues /strainbreast lesion) was calculated by the software equipped with the ultrasonic machine.Pathology of the lesions after biopsy or operation was considered as standard,SRs of benign and malignant breast lesions were compared with independent-samples t test.The diagnostic value of SR was evaluated by receiver operating characteristic (ROC) curve analysis.Results SRs of 34 benign breast lesions and 30 malignant breast lesions were 2.85 ± 1.30 and 5.03 ± 2.50 respectively,there was significant difference between them( t =- 4.29,P =0.000).Area under the curve of diagnosing benign and malignant of breast lesions was 0.875 for SR( P ＜0.0001).If the cut-off point of SR was 3.26,the sensitivity in differentiating breast lesions was 83.33％,while the specificity was 82.35％.Conclusions SR is a helpful elasticity parameter for differentiating benign and malignant breast lesions of BI-RADS Ⅳ diagnosed by conventional ultrasound.

OBJECTIVE: To observe the CT three-dimensional imaging features of the frontal recess region with advanced three-dimensional reconstruction, and develop the real image of the important anatomical structures around the region to conduct surgery. METHOD: Thirty patients were undergone spiral CT by 16 line high speed spiral CT, and multiplanar reconstruction images using standard three-dimensional reconstruction protocol on a computer workstation. The structure of the frontal recess, the agger nasi cell and adhere style of the uncinate process were observed. The parameter of the important anatomic structure of frontal recess was measured precisely. RESULT: After the reconstruction, we get the three-dimensional model very close to the true state of the nasal cavity-sinuses cell, in which parts of the frontal recess can clearly identify the agger nasi cell, frontal cell and other important structures. In these patients, the height, width and depth of the agger nasi and frontal sinus were (9.45 ± 3.60)mm, (8.08 ± 3.37)mm, (26.98 ± 6.82)mm and (26.86 ± 9.45)mm, respectively. CONCLUSION This study tried to develop the standardized techniques and measurements from three-dimensional reconstructed images of the frontal sinus and to ascertain the usefulness of the frontal sinus in identification of patients.

OBJECTIVE: To examine the expression of Twist1 in cervical cancer and to explore its biological function in the progression of cervical cancer.
 METHODS: The expressions of Twist1 in 32 cervical cancers and matched normal tissues were examined by immunohistochemistry (IHC). Cell invasive ability and the expression of invasion-related genes were determined in RNAi-based Twist1-silencing HeLa cells. The relationship between Twist1 and microRNA-33a (miR-33a) in cervical cancer was studied by Pearson correlation analysis, and the roles of miR-33a in regulation of Twist1 and cell invasiveness were studied.
 RESULTS: The positive expression rate of Twist1 was 75.0% (24/32) and 21.9% (7/32) in the cervical cancer and the matched normal tissues, respectively, with significant difference between them (P<0.05). Twist1 shRNA significantly decreased the invasiveness of HeLa cells (P<0.05). Compared with the matched normal tissues, the expression of miR-33a was increased in the cervical cancer tissues, which was negatively correlated with Twist1 (r=-0.661, P<0.05). Overexpression of miR-33a could significantly suppress Twist1 expression as well as cell invasiveness (P<0.05).
 CONCLUSION Twist1 is critical for the invasiveness of cervical cancer cells; miR-33a, as a tumor suppressor gene, functions as an upstream regulator of Twist1 and is involved in the invasiveness of cervical cancer cell.

【Objective】 To investigate the effect of serological methods for eliminating the interference of warm autoantibodies with the compatibility test before blood transfusion. 【Methods】 The blood samples (whole blood and serum, 3 mL/each) of 10 cases of warm autoantibodies interfering with antibody screening and identification were collected. Autogenous or allogeneic red blood cells(RBCs) were treated with microthermal(45 ℃), chloroquine, or ZZAP (dithiothreitol and papain) reagents, and then were used to absorb the autoantibodies in patients′ plasma. The plasma after absorption and RBC elution were used for antibody identification by anti-human globulin method or Polybrene method to determine the specificity of the autoantibody/alloantibody. Blood transfusion with ABO/Rh homotypic RBCs without corresponding antigens was performed in patients with alloantibodies or specific autoantibodies, and the efficacy of blood transfusion was evaluated. 【Results】 The interferenc of warm autoantibodies with antibody screening and identification due to primary or secondary autoimmune diseases were eliminated after absorption, and IgG isospecific antibodies (anti-E, anti-Jk^a, anti-Wr^a) in 3 cases and specific autoantibodies (anti-Ce) in 1 case were yielded. 6 of the 10 patients received blood transfusion, and 4 with specific antibodies avoided exposure to corresponding antigens. After transfusion of 2U suspended RBCs, the increase of hemoglobin at 24h in all 6 patients was greater than 10 g/L, and no hemolytic transfusion reaction occurred. Anemia symptoms were improved after transfusion. 【Conclusion】 Appropriate elution methods and autologous/allogeneic absorption methods can eliminate the interference of warm autoantibodies with the identification of alloantibodies, therefore can accurately identify the types and properties of antibodies, thus providing targeted and effective blood transfusion.

ObjectiveTo analyze the monitoring data of schistosomiasis from 2004 to 2021 in Suzhou New District， Jiangsu Province， and to provide evidence for improving schistosomiasis elimination strategies. MethodsFollowing the Opinions on Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou and the Technical Plan for Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou， the monitoring of schistosomiasis in the population and snail habitats from 2004 to 2021 was conducted. The Mann-Kendall method and Joinpoint regression method were employed to analyze the trend of epidemic indicators （such as seropositive rate， prevalence of snail frames， etc.）. Time series analysis （exponential smoothing model） was conducted to predict snail occurrence. ResultsFrom 2004 to 2021， a total of 73 680 people were serologically tested for schistosomiasis， with a positive rate of 0.084%. The seropositivity rate showed statistically significant differences between different years （χ²=70.73， P<0.05）， but there was no significant trend over time. In addition， 3 053 fecal tests were conducted and no positive result was found. The snail habitats covered an area of 70.11 hm² and showed a decreasing trend （Z=-1.97， P<0.05）. A total of 30 093 frames were surveyed， of which 19.038% contained snails. The difference in the prevalence of snail frames between different years was statistically significant （χ²=7 203.09， P<0.05）， with a decreasing trend in the prevalence of snail frames （Z=-2.05， P<0.05）. A total of 26 296 live snails were seized and density of live snails was 0.874 snails per frame， showing a decreasing trend in the density of live snails （Z=-2.35， P<0.05）. A total of 12 391 snails were dissected and no infected snail was found. The areas treated with molluscicides remained stable at 264.60 hm². An area of 27.77 hm² achieved the goal of snail eradication through environmental modification， with a decreasing trend （Z=-2.44， P<0.05）. It is estimated that the prevalence of snail frames and snail density will remain relatively stable from 2022 to 2026， but the snail habitat area will fluctuate significantly， showing an increasing trend. ConclusionNo indigenous cases of schistosomiasis and no infected snails are reported， indicating the successful consolidation of schistosomiasis prevention and control measures. However， the snail habitat area fluctuates greatly with an increasing trend， suggesting the need for long-term Oncomelania snail monitoring in local areas.
