Bilingual teaching is very important to the development of medical education and integration with the advance medicine knowledge in the world.Rich teaching experiences have been summarized during these years.This article summarizes the bilingual teaching experience from four parts including the concept of bilingual education,conditions of bilingual education,methods of bilingual education,results of bilingual education.We have also found some problems during teaching and worked out the improvement methods.

Objective:To establish a rat model of erectile dysfunction caused by the injury of the cavernous nerve. Methods:Rats topographical anatomy were done for identifing the cavernous nerve and major pelvic ganglion and pelvic nerve and hypogastric nerve .Polygraph intracavernous pressure of the models were detected continuously and evaluated. Results:Erectile process was controlled by erectile nerve. Major pelvic ganglion includes two inflows,they are called pelvic nerve and hypogastric nerve. The largest outflow is cavernous nerve. The injury of the cavernous nerve will lead to erectile dysfunction. Conclusion:Rat can be an ideal animal model for studying the erectile dysfunction caused by cavernous nerve injury. The neuvological mechanism of erectile dysfunction can be evaluated with determination of intracavernous pressure.

Objective To analyse the airway reversibility and variability for bronchial asthmatic patients .Methods The status of test positive ratio and combined airflow limitation were analysis for 650 Clinical diagnosed asthmatic patients .527 cases were given bronchial dilation test and 123 cases were given provocative test .Results Positive ratio of 527 cases bronchial dilation test was 41 . 4% .Positive ratio of 123 cases provocative test was 52 .0% .The airflow limitation(FEV1/FVC% <70% ) ratio of total 650 cases was 34 .0% .In the 193 cases of combined airflow limitation patients which was given bronchial dilation test ,the positive ratio of bronchial dilation test was 61 .7% .Conclusion Bronchial dilation test need repeat because of its less sensitivity .The positive ratio of provocative test is not high ,so the patients of provocative test negative couldn′t exclude the diagnosis of asthma .The ratio of bronchial dilation test was high for combined airflow limitation asthmatic patients .Its may clew that the patients combined airflow limitation may be exacerbation and need actively therapy .

Objective To evaluate the clinical efficacy and safety of stereotactic radiotherapy (SRT) combined with bevacizumab for brain metastases in patients with lung adenocarcinoma.MethodsThe clinical data of 95 patients with brain metastases of lung adenocarcinoma were retrospectively analyzed, including 36 patients treated with SRT and bevacizumab (bevacizumab group) and 59 patients treated with SRT, corticosteroids, and mannitol (traditional drug group).The tumor response rate, peritumoral edema control rate, improvement in Karnofsky Performance Scale (KPS) score, and adverse reactions were analyzed.Results Compared with the traditional drug group, the bevacizumab group had significantly higher tumor response rate (P=0.033) and peritumoral edema control rate (P=0.000) at 1-4 weeks after treatment, as well as an obvious improvement in KPS score and reduced doses of corticosteroids and mannitol.In addition, the adverse reactions in the bevacizumab group were mild and controllable.Conclusions SRT combined with bevacizumab for brain metastases in patients with lung adenocarcinoma can achieve higher short-term tumor response rate and peritumoral edema control rate and improve patients' quality of life.

Trauma and surgery sometimes cause erectile dysfunction because of injury to pelvic nerves and cavernous nerves of the penis. The ideal treatment is to make the injured nerves regenerate themselves and erectile function recover completely. This paper reviews the recent advances in the studies of erigentes regeneration and plerosis following injury in order to find the best method to enhance erigentes regeneration.

Objective:To translate and revise the Arteriovenous Fistula Assessment Scale (AVF-AS), test the reliability and validity of the Chinese version of AVF-AS.Methods:The modified Brislin translation model was used to translate, back translate and cross culture adjust AVF-AS, forming the Chinese version of AVF-AS. Using the convenient sampling method, 220 hemodialysis patients from the First Affiliated Hospital of Zhengzhou University were selected for investigation from July to September 2022. Two weeks later, 30 patients were randomly selected for retesting. The valid data were used for project analysis and reliability and validity evaluation.Results:The Chinese version of AVF-AS consisted of 3 factors and 18 items. Consistency level between evaluators was 0.94, the item level content validity index was 0.83-1.00, average scale level content validity index was 0.94, and the calibration validity was 0.68.Three common factors(autogenous arteriovenous fistula blood flow, stenosis and ischemia, puncture location) were extracted from exploratory factors, and the cumulative variance contribution rate was 75.255%. The total scale's Cronbach α was 0.946, the half reliability of each dimension was 0.826 - 0.898, and the test-retest reliability was 0.907.Conclusions:The Chinese version of AVF-AS has good reliability and validity, and can be used as an effective tool to evaluate the autogenous arteriovenous fistula functional status of hemodialysis patients in China.
