Chinese Journal of Postgraduates of Medicine 2014;37(12):7-9
Objective To analyze the mechanical stimulation to the endometrium on the clinical pregnancy rate and embryo implantation rate in the frozen thawed embryo transfer of hormone replacement therapy.Methods There were 193 patients undergoing the frozen thawed embryo transfer of hormone replacement therapy.According to the endometrial condition on the second or third day of the menstrual cycle,they were divided into three groups.Group A,54 patients whose endometrial thickness was no less than 0.6 cm or abnormal endometrium were operated the mechanical stimulation.Group B,55 patients whose endometrial thickness was no less than 0.6 cm or abnormal endometrial were not operated the mechanical stimulation.Group C,84 patients whose endometrial thickness was less than 0.6 cm and normal endometrium.Each group was divided into blastomere transplantation and blastula transplantation.Group A was 23,31 patients,group B was 24,31 patients,group C was 39,45 patients.The age,number of embryo,level of estradiol when injecting chorionic gonadotrophin,clinical pregnancy rate and embryo implantation rate were compared.Results (1) The clinical feature of blastula transplantation.The age,number of embryo,embryo implantation rate among three groups had no significant difference (P > 0.05).The clinical pregnancy rate in group A and group C was significantly higher than that in group B [73.91% (17/23),69.23% (27/39)vs.37.50%(9/24)] (P < 0.05),and there was no significant difference between group A and group C (P > 0.05).The level of estradiol when injecting chorionic gonadotrophin in group C was significantly higher than that in group B [(841.56 ± 802.73) μ g/L vs.(293.34 ± 69.14) μ g/L] (P < 0.05).There was no significant difference between group A and group B,group A and group C (P >0.05).(2)The clinical feature of blastomere transplantation.The age,number of embryo,level of estradiol when injecting chorionic gonadotrophin,embryo implantation rate and clinical pregnancy rate among three groups had no significant difference (P > 0.05).Conclusions Mechanical stimulation to the endometrium can significantly improve the clinical pregnancy rate of blastula transplantation.It has no improvement for embryo implantation rate and clinical pregnancy rate of blastomere transplantation.
2.Immunotherapy of biliary tract cancer
Journal of International Oncology 2015;(8):635-637
Biliary tract cancer (BTC)is one of the most aggressive malignancies with only 1 0% early-stage diagnosis rate.For advanced BTC,regimen of gemcitabine and cisplatin has been regarded as the first line standard combination,but the curative effect is still unsatisfied.Infiltration of immune cells and immune-related microenvironment can inhibit various types of cancers.In BTC,higher frequencies of tumor-infiltrating CD8 + cytotoxic T cells and CD4 + T cells are closely associated with favorable prognosis.These findings have provided the rationale for further development of immunotherapies as a novel treatment modality against BTC.

Objective: To compare the difference of family environment and other factors having influence on academic achievement of university students between freshmen in one key-university and another un-key-university Methods: 3995 freshmen (2214 from a key university of Beijing, 1781 from an un-key university of inner Mongolia) were investigated with the EMBU scale and the General Information Questionnaire Results: The freshmen of the two universities had different experience in nearly all aspects investigated, including parental rearing behavior, educational levels, occupation, family type, family economic status, etc Parenting styles of parents, poor parental relationship, lower income and educational level, residency and race had effect on academic achievement of the freshmen Conclusion:Freshmen in different universities have different family environment and parental rearing

Objective To explore the distribution,fundamental diseases,risk factors and drug-resistance of hospital- acquired infection caused by fungi in Department of Respiratory Medicine.Methods The clinical data of 142 patients were retrospectively reviewed,and then with statistical analysis was performed.Results The main pathogen which caused fungal hospital-acquired infection was Candida albicans. The most three possible fundamental diseases were chronic obstructive pulmonary disease,bronchiectasis and lung cancer. The main risk factors were lower resistibility of patients and invasive diagnostic and therapeutic measure. The fungus resistance was gradually rising.Conclusion The hospital infection caused by fungus should be emphasized in respiratory medicine department. In order to effectively prevent the hospital infection in respiratory medicine department,we should improve the basic conditions of patients,rationally diagnose and treat,and rationally use the drug against fungi.

Objective To explore the effects of L-Arginine on diabetic vascular endothelial function. Methods 60 patients with Diabetes were randomly divided into two group:placebo control group(30 patients)and L-Arginine group(30 patients). Patients in L-Arginine group were taken L-Arginine 7g a day. All patients were treated for 28days and other 7days for elution. The plasma concentration of nitric oxide(NO) and endothelin (ET), vWF were measured in each group before and after the experiment. Flow Mediated Dilation(FMD) function of brachial artery of all patients were measured by high resolution vascular ultrasound. Results After the experiment, the plasma concentration of NO in L-Arginine group was higher than that of placebo group, meanwhile the plasma concentration of ET and vWF were lower than placebo group (P < 0. 05). Moreover, FDM in L-Arginine group were significant higher than placebo group(P < 0. 05). Conclusion L-Arginine could protect the vascular function in the diabetic patients.

Objective To explore the effect of advanced glycosylation end products (AGEs) on expression of connective tissue growth factor (CTGF) in cultured rat vascular smooth muscle cells (VSMCs) and the mechanism of accelerated atherosclerosis in diabetes. Methods VSMCs were isolated and cultured from the thoracic aorta of rat. Reverse transcription polymerase chain reaction (RT-PCR) and Western immunoblot analysis were used to detect the expression level of CTGF mRNA and protein. Results The expression of CTGF mRNA and protein were increased by AGE-BSA in the time- and dose-dependent manners(P<0.05). Conclusions AGEs may increase the expression activity of CTGF in cultured vascular smooth muscle cells.

Objective To investigate the effectiveness and safety of applying compound lidocaine cream on tracheal mucosa as topical anesthesia to reduce the stress reaction during extubation of tracheal tube. Methods Sixty patients (aged 18-65yr,body weight 40-80kg,ASA Ⅰ-Ⅱ) scheduled for elective surgery under general anesthesia were selected,and they were randomly divided into compound lidocaine cream group (group L,n=30) and control group (group C,n=30). Orotracheal intubation was performed in all the patients. Compound lidocaine cream was uniformly smeared on the foremost third of endotracheal tubes before intubation in group L,and no drug was coated on endotracheal tubes in group C. The changes in blood pressure and heart rates during extubation,the use of hypotensive drugs,cough reflex,breath holding,sore throat and pharyngeal discomfort after extubation were compared between the two groups. Results The operation and intubation time of the two groups showed no significant difference. The blood pressure and heart rate during extubation,the rate of using hypotensive drugs,and the incidence of cough reflex and breath holding were lower in group L than in group C,while the foreign body sensation in pharynx were after extubation was more frequent in group L than in group C. The incidence of pharyngodynia was similar in the two groups,and the pharyngodynia and foreign body sensation in pharynx markedly improved one day after operation in both groups. Conclusion Topical anesthesia of tracheal mucosa using compound lidocaine cream may reduce the cough reflex and breath holding during extubation,and inhibit the stress reaction.
