Objective] The article summarizes the experience of using sanren decoction to treat pediatric diseases by Professor Liu Lin, the famous TCM physician of Hubei. [Methods] Through following Professor Liu Lin clinical diagnosis, organize his medical records, summarize the experience and thoughts of using Sanren decoction to treat pediatric diseases, and for some cases. [Results] Professor Liu Lin believes that the physiological and pathological characteristics of children prone to cause hot and humid accumulation, pediatric Chih-Yin is not substantial, with their lungs often delicate and spleens often inadequate, they prone to get hot and humid accumulation after sick, and later appear a variety of symptoms including upper burner, center burner and lower burner. Therefore, the treatment of pediatric disease should take the heat into account, bearing in mind the residence site of heat evil and syndrome differentiation. Professor Liu Lin makes good use of Sanren decoction to treat a variety of pediatric diseases, judging the residence site of heat evil and clinical manifestations, giving the corresponding treatment flexibly. Such as the treatment of bronchitis with almonds as the monarch herb to expectorant cough, treatment of infantile anorexia with White Kou Ren as the monarch herb to activate spleen and remove dampness, treatment of children with nephrotic syndrome with Yiyiren as the monarch herb for penetration of water, treatment of HFMD with the Sanren to regulate Qi of triple burner, according to the symptoms to medicate and always has good clinical effect. [Conclusion] Professor Liu Lin using Sanren decoction to treat pediatric diseases is effective, his thought is worthy of depth study and promotion.

Objective To explore pre C and YMDD motif mutant of hepatitis B virus during lamivudine therapy. Methods From five chronic hepatitis B patients with serum HBeAg seroconversion but HBV DNA positive by polymerase chain reaction(PCR) following lamivudine therapy, sequences of the pre C and P genes of hepatitis B virus were analyzed by direct PCR product sequencing methods. Results All the five patients were observed to have G to A variations at nucleotide 1896. However, such mutations were observed only in 2 of the 5 patients before HBeAg seroconversion emerged. Meanwhile YMDD mutations were found in all the five patients during lamivudine therapy three of which were M552I mutants, two were M552I associated with L528M. One of the five patients had no reaction to the therapy, four had HBV DNA breakthrough during therapy. Conclusions The mutants of pre C associated with YMDD mutations may arise in the patients with HBeAg seroconversion and positive HBV DNA during the treatment of lamivudine. HBV DNA should be detected in the patients with HBeAg seroconversion to exclude the pre C mutation.

Post-stroke aphasia refers to acquired language disorder caused by cerebrovascular disease.As part of cognitive function,language is closely related with other non-linguistic cognitive function.In recent years,many scholars have begun to pay attention to the relationship between language disorder and non-verbal cognitive function in patients with post-stroke aphasia.This paper describes the epidemiology of cognitive impairment in patients with post-stroke aphasia,and summarizes the relationship between language obstruction and the non-language-based cognitive function in patients with aphasia after stroke (such as working memory,attention,execution,etc.) to provide a direction for further research.

Objective To evaluate serum level of pepsinogenⅠ( PGⅠ) ,PGⅡ, and PGⅠ/PGⅡ-ratio ( PGR ) using latex enhanced turbidimetric immunoassay in patients with different gastric mucosal lesions, and to investigate their changes and clinical significance.Methods Case-control study.Two hundred and seventy-five patients who had enteroscopy and pathological examination from the department of gastroenterology and surgery from Beijing Tongren Hospital between January 2015 and January 2016 were enrolled.Endoscopic and histopathological examination confirmed the normal control group (n=20), chronic non-atrophic gastritis group ( n=68 ) , chronic atrophic gastritis group ( n=76 ) , including antral atrophic gastritis ( n=30 ) , gastric body atrophic gastritis ( n=26 ) , and multifocal atrophic gastritis ( n=20 );intestinal metaplasia group ( n=28 ) , intraepithelial neoplasia group ( n=9 ) , benign gastric ulcer group ( n=46) and intestinal gastric cancer group ( n=28).Latex-enhanced immune turbidity method were used to detect the patients fasting serum PGⅠand PGⅡ.Then the PGR was calculated.The normally distributed data of each group were statistically analyzed by ANOVA, the data between groups were nalyzed using the Mann-Whitney U test and Kruskal-Wallis test.Results Serum PGⅠ[ ( 74.23 ±22.36 ) ] ng/ml and PGR (6.92 ±2.16) in chronic atrophic gastritis group were lower than those in normal controls[PGⅠ(98.94 ± 21.00) ng/ml, PGR 8.13 ±2.47],(FPGⅠ =18.297,PPGⅠ <0.01,FPGR =4.713,PPGR <0.01).The serum PGⅠ[(44.46 ±26.72) ng/ml] and PGR (3.09 ±0.83) in the intestinal type of gastric cancer group were lower than those in the chronic atrophic gastritis group[PGⅠ(74.23 ±22.36)ng/ml, PGR 6.92 ±2.16], (ZPGⅠ =-3.921,PPGⅠ <0.01,ZPGR =-6.662,PPGR <0.01).PGⅠ[(129.95 ±43.39) ng/ml].PGⅡ[(21.09 ±6.78) ng/ml]in the gastric benign ulcer group were higher than those in the normal controls[PGⅠ (98.94 ±21.00) ng/ml, PGⅡ(12.64 ±1.84) ng/ml], FPGⅠ =10.803,PPGⅠ <0.01;FPGⅡ =39.130,PPGⅡ <0.01. PGⅠ[(52.44 ±10.37) ng/ml and PGR (5.47 ±1.59) in the multifocal atrophic gastritis group were lower than those in the antral atrophic gastritis[PGⅠ(94.95 ±14.45)ng/ml, PGR 8.39 ±1.48],ZPGⅠ =-5.941,PPGⅠ <0.01,ZPGR =-4.911,PPGR <0.01.The AUC of PGⅠand PGR for diagnosis of chronic atrophic gastritis were 0.752 and 0.683 respectively.The sequence combined detection sensitivity was 72.37%(55/76), and the specificity was 70.85%(141/199).The AUC of PG I and PGR for diagnosis of intestinal type of gastric cancer were 0.852 and 0.895 respectively.The sequence combined detection sensitivity was 71.42% ( 20/28 ) and the specificity was 81.78% ( 202/247 ) . Conclusion The Latex-enhanced immune turbidity method of combined detection of serum PGⅠ, PGⅡlevels and PGR can be used in the clinic to monitor the status and function of gastric mucosa and are informative for gastric cancer and precancerous lesions of gastric mucosa.

Objective To detect the antibiotic resistance of four kinds of gram-negative bacilli strains against seven antibiotics and to analyze the differences in antibiotic resistance between the strains isolated in intensive care unit (ICU) and common wards.Methods This study involved 3 238 gram-negative bacilli strains isolated in Beijing Tongren Hospital from January to December 2016.Of all strains, 46.6% were isolated in ICU (severe group) and 53.4% were isolated in common wards (general group).Resistance of these strains to seven kinds of antibiotics was detected and the differences between the two groups were analyzed.Results Antibiotic resistance rates of Pseudomonas aeruginosa strains to ceftriaxone, cefepime and imipenem were 41.7%, 41.2% and 39.5% in severe group and 20.9%, 21.7% and 17.1% in general group.Moreover, the differences between the two groups were all statistically significant (χ2Cefatriaxone=56.72, P<0.01;χ2Cefepime=49.12, P<0.01;χ2Imipenem=69.81, P<0.01).Antibiotic resistance rates of Klebsiella pneumoniae strains to imipenem was 17.2% in severe group and 8.8% in general group, and the difference between the two groups was statistically significant (χ2Imipenem=11.48, P<0.01).Resistance rates of Escherichia coli strains to ceftriaxone and cefepime were 72.9% and 35.8% in severe group and 44.7% and 13.3% in general group, and the differences between the two groups were statistically significant (χ2Ceftriaxone=40.13, P<0.01;χ2Cefepime=41.61, P<0.01).More than 60% of Acinetobacter baumanii strains whether they were isolated in ICU or in common wards were resistant to all the seven antibiotics, and there were no significant differences between the two groups.Conclusion Gram-negative bacilli strains isolated in ICU have higher resistance rates than those isolated in common wards and therefore antibiotics should be used differently.Regular monitoring of drug resistance should be strengthened to provide references for empirical clinical medication.

To understand the personality characteristics and temperament type of medical students in Xi'an Jiao tong University,and to provide scientific evidence for their targeted mental intervention by analyzing graphs about Eysenck personality questionnaire revised in China.,310 medical students were investigated by using EPQ(adult version).We found that there were more male students with typical psychoticism personality than female students with the same personality,and there was statistical significant difference in the distribution of the type of temperament between male and female students.Medical students with stable personality probably accounted for two-thirds of the total.Female students were mainly manifested unstable personality with extraversion,while male students were unstable introvents.In future we should take targeted psychological intervention measures.We are supposed to focus on each student's personality characteristic,temperament type and other specific conditions for a variety of education.
