Objective:To explore the efficiency of a new scoring system of gastric cancer screening for early gastric cancer in health examination population.Methods:The risk score of gastric cancer was assessed based on the new scoring system in health examination population. A notice for further gastroscopy was sent to the medium-risk and high-risk people. Gastroscopy was performed on those who agreed to undergo the examination.Results:From January to April 2019, a total of 5 357 people in health system visited the Physical Examination Center of Shanghai Songjiang Clinical Medical College of Nanjing Medical University for health examination. Seven hundred and forty people were classified as medium- and high-risk groups by the new screening system, 576 in medium-risk group, and 164 in high-risk group. Among them, 131 cases (17.70%) came for further gastroscopy, of whom 91 (69.47%) were in the medium-risk group and 40 (30.53%) in the high-risk group. After gastroscopy, 4 cases of gastric cancer and 1 case of esophageal cancer were detected, and both were early cancer. In the medium-risk group, 2 cases (2/91, 2.20%) of early gastric cancer and 1 case (1/91, 1.10%) of early esophageal cancer were found. In the high-risk group, 2 cases (2/40, 5.00%)of early gastric cancer were found. The tumor detection rate of high-risk group (5.00%) was higher than that of medium-risk group (3.30%), but there was no significant difference ( P>0.05). Conclusion:Risk stratification with the new scoring system of gastric cancer screening can improve the detection rate of early gastric cancer.

Objective To study the genome DNA methylation in rheumatoid arthirits(RA)and the re- lated factors of DNA methylation.Methods Twenty-first cases with RA and 20 controls were recruited to par- ticipate the study.Plasma Hcy,SAM,SAH,the MTHFR gene C677T polymorphism and the expression of LFA-1 in CD4~+T cells was measured in all patients and controls.Results①The SAM levels were lower sig- nificantly in RA groups than in controls.The SAH levels were higher significantly in RA groups than in con- trols.②There was significant inverse correlation between plasma Hcy level and SAM level(r=-0.932,P＜0.01). There was significant positive correlation between plasma Hcy level and SAH level(r=0.924,P＜0.01).③The expression of LFA-1 in CD4~+T cells was higher significantly in RA groups than in controls.There was a signif- icant positive correlation between LFA-1 expression level and Hcy level(r=0.557,P＜0.01),a significant in- verse correlation between LFA-1 expression level and SAM level(r=-0.651,P＜0.01).④The MTHFR gene mu- tation lead to dramatically increase of Hcy,SAH level and the expression of LFA-1 level in CD4~+T cells and genome DNA hypomethylation.Conclusion①Hypomethylation of genome DNA is found in most RA pa- tients.②The factors associated with genome DNA hypomethylation include MTHFR gene mutation and hyper- homocysteinemia.③The expression of LFA-1 in CD4~+ T cells is higer in RA groups than in controls,which re- lates to the DNA methylation level and the MTHFR gene C677T polymorphism.

Objective To study the protective effect and mechanism of ganciclovir(GCV) on acute cerebral injury of mice caused by herpes simplex virus(HCV). Methods Mice model of acute cerebral injury caused by HCV were established, morphological changes in the brain tissue of mouse treated with GCV were observed under the electronic microscope, and the mortality were compared. The HSV - I DNA copies of brain tissue were detected by fluorescent quantitative polymerase chain reaction. Results In the infected model group, there were obvious swelling, karyopyknosis and destruction of the structure in the brain cells, as well as myelin sheath solution and vacuolar degeneration in the mitochondrion and crest were destroyed. There were the virions in the nucleolus. With the GCV treatment, the symptoms were improved, the mortality much lowered, the yields of HSV - I DNA much lower. Conclusions GCV may restrain replication of HSV-Ⅰ effectively and lower the mortality of mice with acute cerebral injury caused by herpes simplex virus significantly.

Objective To evaluate the gender differences in dose-response curve with cisatra-curium in epileptics.Methods Eighty ASA grade Ⅰ or Ⅱ epileptics were enrolled in this study.All patients were divided into male and the female groups and received the method of single dose injection under midazolam-fentanyl intravenous anesthesia.Each patient received intravenous bolus of 20,30, 40,50μg/kg of cisatracurium respectively.The neuromuscular block was measured by Neuromuscular Transmission Monitor and the responses were defined in terms of the percentages of maximum sup-pression in T1 of TOF of the adductor pollicis muscle.According to log-probit transformation of the data of dose and response,the dose-response curve of cisatracurium was established through linear re-gression.The onset time of cisatracurium was also observed.Results The ED50 ,ED75 ,ED90 ,ED95 values of cisatracurium in male epilepsy patients were 37.2±9.7,48.1±11.3,60.4±12.8,69.3± 14.0 μg/kg and that of female epilepsy patients were 36.6±4.3,47.5±7.7,60.5±14.0,70.1± 19.4 μg/kg.There was no significant difference between the two gender groups.No significant change in onset time was observed among 4 dose groups.Conclusion No gender differences are ob-served in dose-response curve of cisatracurium in epileptics.

OBJECTIVE: To evaluate the long-term efficacy and safety of ultrasound-guided percutaneous nephrolithotomy (PCNL) in the treatment of patients with solitary kidney stones. METHODS: The clinical data of 22 patients with solitary kidney stones treated with PCNL in Peking University People's Hospital from September 2008 to June 2014, with the follow-up data of more than 5 years were analyzed retrospectively. Perioperative indicators, postoperative stone free rate (SFR) and incidence of complications were recorded. Ultrasonography was used to evaluate the long-term stones recurrence rate. Serum creatinine and estimated glomerular filtration rate (eGFR) were used to assess the long-term renal function. RESULTS: In this group of 22 patients, the average age was (50.3±11.8) years, with 10 cases of anatomic solitary kidneys, 12 functional solitary kidneys, and the median stone diameter was 1.65 (1.1-3.9) cm. All the patients had multiple stones, including 7 cases of staghorn stones. The median pre-operative serum creatinine was 104.5 (60.0-460.0) μmol/L, and the mean eGFR was (60.3±29.4) mL/min, showing no statistically significant difference compared with that before surgery. The mean operative time was (88.2±42.0) min, and there were 11 cases of single-channel and double-channel PCNL. The median serum creatinine on the first day after surgery was 102.0 (63.0-364.0) μmol/L, and the mean eGFR was (58.0±25.1) mL/min. The mean postoperative hospital stay was (8.7±5.2) days. In this group, 5 patients (22.7%) presented short-term complications, among which 4 patients presented postoperative infection and massive hemorrhage at the same time, which improved after conservative treatment, and 1 patient presented pleural injury and improved after closed thoracic drainage. Two patients (9.1%) developed long-term complications, and ureteral stricture occurred 3 months after operation, which improved after balloon dilatation. The median follow-up time was 6.2 (4.7-11.1) years. The median serum creatinine at the last follow-up was 104.0 (72.4-377.0) μmol/L, and the mean eGFR was (60.1±23.7) mL/min, showing no statistically significant difference compared with that before surgery. Renal function decreased in 6 patients (27.3%). Initial and final SFR were 72.7% and 100%, respectively. During the 6.2-year follow-up, 9 patients (40.9%) experienced recurrence of kidney stone. After stone recurrence, 13 lithotomy surgeries were performed, and the SFR by the latest follow-up was 63.6%. CONCLUSION This study had the longest follow-up time for patients with solitary kidney stones after PCNL reported at home and abroad. Ultrasound-guided standard PCNL was safe and effective in the treatment of solitary kidney stones. Long-term follow-up results showed that the recurrence rate of kidney stones was still high, but the long-term renal function was stable after operation, and some patients showed mild renal function decline.

Objective To evaluate the efficacy and safety of domestic human recombinant FSH (rhFSH) in women with anovulation of WHO groupⅡ. Methods A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group (domestic rhFSH, n=352) and control group (imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome (OHSS) and adverse events were observed. Results No statistical significant differences (P>0.05) were observed between the two groups in terms of the efficiency on mature follicle [91.8%(323/352) versus 88.8%(159/179)], ovulation rate [91.3%(295/323) verus 90.6%(144/159)], clinical pregnancy rate [19.2%(62/323) verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group (P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group [(9.8±2.2) versus (11.4± 0.6) days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group [(879 ± 419) versus (1 043 ± 663) U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group [21% (13/62) versu 10% (3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups (P>0.05), and no other adverse events were observed in test group during treatment. Conclusion Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO groupⅡ.
