AIM: To observe the effect of diammonii glycyrrhizinatis (DG) on collagen synthesis induced by angioplasty in rabbits. METHODS: The right common carotid artery of male rabbits were injured with 3.5F balloon catheter. Four weeks after operation, arterial tissure collagen content, serum procollagen type I(PCI), procollagen type Ⅲ(PCⅢ) concentration, neointimal thickness and the rate of stenosis were measured.RESULTS: Arterial tissue collagen content, serum PCI, PCⅢ concentration, neointimal thickness and the rate of stenosis of low and high dose DG group is lower than those of injured group.CONCLUSION: DG could inhibit collagen synthesis and neointimal proliferation of rabbits carotid artery induced by angioplasty. It suggests that DG might have clinical potential prespective in prevention and therapy of restenosis.

Background and purpose:Angiofollicular lymphoid hyperplasia(Castleman's disease,CD) is a rare kind of abnormal disease with lymphoid hyperplasia. We analyzed the clinical data of 21 patients with pathologically-confirmed CD. Methods:Twenty-one cases,including 10 males and 11 females with a mean age of 38.6 years,with CD were collected from January 1971 to December 2007 in this study. The disease was divided into localized type(n=19) and disseminated type(n=2) . The clinical data,CT images and pathological and surgical results were restrospectively analyzed. Results:All cases were categorized as hyaline vascular type. In 19 cases with localized type of CD,the lesion presented as a solitary soft-tissue mass with a mean diameter of 5.2 cm,located at the left and right hilus of the lung(n=3 and 2 respectively) or in the interior lung(n=3) ,in the thoracic wall(n=2) or in the mediastinum(n=9) . Two cases of disseminated type were characterized by many groups of thoracic lymphadenopathy with a mean diameter of 2.3 cm,without other organ involvement. On plain CT scan,the mean CT value was 42 Hu. After contrast administration,obvious homogeneous enhancement was observed in arterial phase with CT value of 112 Hu. The preoperative misdiagnosis by CT was 90.5%. Conclusion:CD have no specifi c CT characteristic,its verifi cation is mainly based on pathologic examination. Surgical resection for localized type of CD is curative,but for disseminated CD,multidisciplinary therapies are recommended.

Objective:To analyze the clinical features, treatment and prognosis of asymptomatic patients with retinoblastoma.Methods:A retrospective series of case study. Eight asymptomatic patients (11 eyes) with the diagnosis of retinoblastoma by screening enrolled in Department of Ophthalmology of The Eye-ENT Hospital of Fudan University from January 2006 to March 2019 were included. There were 6 males and 3 females ranging from 2 days to 20 months, with a median age of 6 months. Five patients were unilateral retinoblastoma while 3 patients were bilateral. Based on the International Classification of Intraocular Retinoblastoma, 4 eyes were stage A, 3 eyes were stage B and 4 eyes were stage C. One patient had family history. Four patients were evaluated the Rb1 mutation. Routine ophthalmic examinations and ultra-wide field fundus imaging were performed on the 16 parents and 3 siblings of the 8 patients. Systemic intravenous chemotherapy was performed using the Carboplatin, Vincristine, Etoposide protocol, intra-arterial chemotherapy using Carboplatin and Melphalan, and local treatment involved cryotherapy and transpupillary thermotherapy. The mean follow-up time is 47.25 months.Results:None of the 8 children had any ocular symptoms. Six patients received intravenous chemotherapy (5-6 times), 1 patient received intra-arterial chemotherapy (3 times), and 1 patient just received local treatment. Among the 11 eyes, 9 eyes were treated with local cryotherapy and 8 eyes were treated with transpupillary thermotherapy. During the follow-up period, 2 patients had new tumor, and the average time was 6.3 months after the last chemotherapy. At the last follow-up, the tumor disappeared in 11 eyes, remained stable in 11 eyes. The eye protection rate was 100% (8/8) for patients without eyeball excision. The best corrected visual acuity was 0.1 for 3 eyes and 1.0 for 5 eyes. Three eyes were not found. One heterozygous mutation of Rb1 gene [1c.35_69del (p.T12fs)] was identified in 1 patient, and the other 3 patients were not detected. One had bilateral bulbar tuberculosis of the 16 parents, 1 had bilateral RB of the 3 siblings. They were the mother and brother of a child with bilateral RB.Conclusions:Fundus screening is helpful for the detection of early RB. The eye protection rate is high and the long-term vision prognosis is good after systemic or topical chemical drugs (IVC, IAC) and ocular topical treatment (cryopreservation and transpupillary thermotherapy).

Objective To analyze the current situation of domestic research on fetal surgery by the method of literature measurement, and analyze the development trend.Methods The key words of ‘fetal surgery’or ‘fetal surgery’were searched respectively as the theme, keyword and Title Retrieval in CHKD Database,Wanfang Data knowledge service platform (Wanfang Data),VIP Chinese Journal database (CQVIP)and Chinese biomedical literature database (CBM).Results The result showed that the literature of fetal surgery increased obvi-ously by NoteExpress,especially after 2013.Some hot words of literature about fetal surgery included prenatal diagnosis,ultrasound,fetal sur-gery,prognosis and complications.The major authors’units located in Guangdong,Liaoning,Shanghai,Zhejiang,Sichuan and other regions. The affiliated Shengjing Hospital of China Medical University,Maternal and Child health Hospital of Foshan City in Guangdong Province,the First Affiliated Hospital of Zhongshan University were as the main research institutions.The literatures were classified by the subject of the ob-stetrics and gynecology,surgery,clinical medicine,pediatrics,oncology,the two accounted for more than 50%.The distribution of journals published this type of literature were more broad,and the content was more dispersed.Conclusion The development of the fetus is still in the early stage of development,which need for more accurate positioning and development of the fund to support its development.

Aim To investigate the role of TGF-β3 in the anti-proliferation effect of ursolic acid(UA)in co-lon cancer cells and the possible molecular mechanism underlying this effect.Methods We introduced crys-tal violet staining,flow cytometry and Western blot as-say to determine the effect of UA on proliferation and apoptosis in HCT1 1 6 cells.The levels of TGF-β3, Smad2 /3 and β-catenin in HCT1 1 6 cell were evaluated by RT-PCR and Western blot.Finally,TGF-β3 inhibi-tor and recombinant adenovirus,and luciferase reporter assay were used to analyze the possible mechanism through which TGF-β3 mediated the anti-cancer effect of UA in HCT1 1 6 cells.Results UA inhibited the proliferation and induced apoptosis apparently in HCT1 1 6 cells.UA down-regulated TGF-β3 both in mRNA and in protein level.Meanwhile,UA decreased the phosphorylation of Smad2 /3 concentration depend-ently,although no significant effect was found on the total protein level of Smad2 /3 in HCT1 1 6 cells.Over-expression of TGF-β3 attenuated the inhibitory effect of UA on the proliferation of HCT1 1 6 cells,while the TGF-β3 inhibitor potentiated this effect. UA sup-pressed the transconduction of Wnt/β-catenin signaling in HCT1 1 6 cells through decreasing the level of β-catenin.Exogenous expression of TGF-β3 increased the level of β-catenin and partly reversed the UA-in-duced decrease of β-catenin.However,TGF-β3 inhib-itor potentiated the inhibitory effect of UA on β-catenin in HCT1 1 6 cells.Conclusion The anti-proliferation activity of UA in colon cancer may be partly mediated through down-regulating TGF-β3 to suppress Wnt/β-catenin signaling at least.

Objective To investigate the usage of defluoridation stove and the formation of related behavior in the disease affected areas and the current situation of coal-burning-borne endemic fluorosis,to evaluate the control effect,so as to provide a theoretical basis for superior department to adjust the control strategy in time.Methods According to The Implementation Plan for Prevention and Treatment of Coal-burning-borne Endemic Fluorosis in Shaanxi Province,Ziyang and Langao in Ankang City were chosen for epidemiological survey.Using stratified sampling method,according to the degree of disease situation,each county was divided into 3 layers and then 5％ from each layer was extracted to carry out an investigation,respectively.The number of investigated village was at least 1,up to 30.The number in a non-endemic area was 1-3.Questionnaire survey of all residents was carried out to ask of the changes of cooking and heating fuel;the correct usage of the improved stove;the changes of life behavior related to the corn and pepper for human consumption and the development of prevention and treatment of post management.In endemic areas and in non-endemic areas,according to the Determination of Fluoride in Foods (GB/T 5009.18-2003),fluoride levels of corn (or rice) and chili which collected from 10 families were determined.Meanwhile,the criteria for Diagnosis of Dental Fluorosis (WS/T 208-2011) was used to diagnose dental fluorosis and the criteria of Urine-determination of Fluoride-ion Specific Electrode Method (WS/T 89-1996) was used to evaluate urine fluoride;dental fluorosis of every child aged 8-12 was examined and 10 copies of urine samples were randomly collected in each age group.Housewives and students over the age of 16 in endemic areas were quizzed of the knowledge of health and diagnosed serious skeletal fluorosis according to The Diagnostic Criteria of Endemic Fluorosis (WS 192-2008).Results The rates of correct usage of improved furnace and oven were 91.43％ (3 019/3 302) and 95.72％ (3 578/3 738).The autonomous maintenance rate of stoves was 0.61％ (49/7 998).In endemic areas,the correct drying rate and the correct storage rate of corn and pepper were all 100.0％ (300/300);the washing rate of corn and pepper before eating was 98.3％ (7 863/7 998).The fluoride median contents of corn and pepper was 0.800 and 2.863 mg/kg,respectively.In non-endemic areas,The fluoride median contents of corn and pepper was 0.443 and 4.065 mg/kg,respectively.The awareness rates of health knowledge were 81.27％ in housewives and 90.32％ in students.Dental fluorosis detection rate of 8-12 years old children was 12.52％ (87/695);the fluoride content was between 0.04-7.00 mg/L and the geometric mean value of fluoride content was 0.61 mg/L in endemic areas.There was no new case of serious skeletal fluorosis.Conclusions The prevention effect is obvious.Disease surveillance,health education and management of defluoridation stoves are keys to prevent coal-burning-borne endemic fluorosis.

OBJECTIVE:To systematically review the effect of CYP2C19 genetic polymorphism on lansoprazole pharmacoki-netics,and provide evidence-based reference for clinical individualized medication of lansoprazole. METHODS:Retrieved from PubMed,EMBase,Web of science,Cochrane Library and CJFD,retrospective studies about the effect of CYP2C19 genetic poly-morphism on lansoprazole pharmacokinetics were collected,Meta-analysis was performed by Rev Man 5.2 software after data ex-tract and quality evaluation. RESULTS:Totally 11 retrospective studies were included,involving 200 patients. The gene type in-cluded homozygote express metabolizers (EM),heterozygous express metabolizers (HEM) and slow metabolizers (PM). Results of Meta-analysis showed CYP2C19 polymorphism significantly affected cmax,AUC,t1/2,tmax and CL/F. The cmax and AUC in group PM were higher than group HEM and group EM;CL/F in group EM was higher than group HEM and group PM;t1/2 in group PM was higher than group HEM and group EM,while there was no significant difference in the t1/2 between group HEM and group EM;tmax in HEM and group PM were higher than group EM,while there was no significant difference in the tmax between group PM and group HEM. CONCLUSIONS:CYP2C19 genetic polymorphism shows obvious effect on lansoprazole pharmacokinetics, which is the key factor for causing efficacy of lansoprazole and individual differences among adverse reactions,and clinic should take into account individualized dose regimen of lansoprazole.
