Retinocytoma is a benign tumor arising from the retina.Since it was first described by Gallie in 1982,retinocytoma has been progressively recognized.More and more clinical and pathological studies indicate that retinocytoma may be a early stage or a type of retinoblastoma.Retinocytoma is difficult to be found because of lack clinical signs.Therefore,it is very important for us to follow-up and screen the families of RB patient in order to intervene with the course of disease as early as possible for preventing and arresting the malignization of retinocytoma toward RB.The name alteration,clinical manifestations,histopathological features,molecular mechanism and heredity characteristics were reviewed.

Objective: To study the relationship between the damage of the central neuron and the brain structure and function of the rats with chronic stress.Methods: Male Wistar rats(n=30) weighting about 185-255g were divided into the test group(T,n=15) and the contral group(C,n=15) randomly.The rats in group T were exposed to various types of stresses every day for consecutive 21 days.The rats in group C did not receive any stress during 21 days.Every rat was weighed,open-field tested and measured for the brain by MR before the test and on the 22nd day.Also,on the 22nd day,the brains were removed and cut coronally.The apoptosis was detected by techniques of terminal deoxynucleotibyl transferase(TdT)-mediated dUTP nick end labling(TUNEL).Results: Weight and the result of Open-field test: compared with group C,group T showed less weight,increased stopping time in the center,decreasing rearing and grooming and increased defecation after 21-day stress(P

Objective To explore the effect of Shenling Baizhu Powder and moxibustion on serum brain-gut peptide in patients with diarrhea predominant irritable bowel syndrome (D-IBS). Methods Sixty D-IBS cases were randomly divided into two groups, 30 cases in the treatment group were given Shenling Baizhu Powder and moxibustion therapy, and 30 patients in the control group were given loperamide hydrochloride capsule. Treatment for the two groups lasted for 4 weeks. Clinical symptoms and serum brain gut peptide (5-HT, VIP and SP) levels of two groups were observed before and after treatment, clinical efficacy were evaluated. Results Markedly effective rate of the treatment group was 66.7% (20/30), better than 33.3% (10/30) in the control group (P<0.05). After treatment, clinical symptom scores of the treatment group decreased significantly (P<0.01), while only diarrhea and abdominal pain improved in the control group (P<0.01), with statistical significance (P<0.01). After treatment, serum 5-HT, VIP, and SP of the treatment group were decreased (P<0.01), while these indexes of the control group did not change significantly (P>0.05), with statistical significance (P<0.01). Conclusion Clinical efficacy of Shenling Baizhu Powder and moxibustion in treating D-IBS is better than that of loperamide hydrochloride capsule, and can significantly improve clinical symptoms and regulate serum brain-gut peptides levels.

Objective To explore the diagnosis and treatment of Kaposiform hemangioendothelioma (KHE),deepen the understanding of KHE and Kasabach-Merritt phenomenon (KMP),and discuss the optimal treatment for KHE.Methods From January 2008 to August 2016,13 cases of KHE were confirmed by surgery or biopsy pathology and admitted to the First Affiliated Hospital of Sun Yat-Sen University,and the clinical diagnosis and treatment were analyzed retrospectively.Results There were 13 patients(7 males and 6 females) with a median age of 1.0 years(0.2-10.0 years),and 84.6%(11/13 cases) were infants and young children,76.9% (10/13 cases) involved with deep tissue,23.1% (3/13 cases) were associated with KMP and they were younger than 1 year old,and 15.4% (2/13 cases) coexisted with hemangioma or lymphangioma.The location,extent and infiltration depth of the lesion were observed by imaging examinations and histopathology showed nodule shaped spindle tumor cells.Radical resection was considered if possible.Dose of Vincristine (0.5 mg/m2 weekly) and Propranolol [1 mg/(kg·d)] were administered.The prognosis was different in thirteen cases undergoing different treatments.After 3 months to 9 years follow-up,41.7% (5/12 cases) survived after tumor treatment.Conclusions KHE happens mostly in infants and young children,with varying clinical manifestations and a high recurrence rate.The diagnosis of KHE is based on histological examination,computed tomography and magnetic resonance imaging while it still need explicit pathological diagnosis is needed.KHE may be accompanied by hemangioma or lymphangioma.Prognosis is affected by many factors and the comprehensive treatment is required.KMP should be remedied preferentially,individual treatment protocol and long term follow-up are necessary.

Objective To explore the risk factors,the distribution of etiology and drug resistance status of patients with early infection (3 months) after liver transplantation,and to provide reference for clinical diagnosis and treatment.Methods The clinical data of 112 recipients from February 2014 to December 2015 were collected,and logistic regression analysis was performed on the risk factors of early postoperative infection in liver transplant patients.The independent risk factors of infection after liver transplantation were screened out.At the same time,the results of pathogen culture and drug sensitivity test were statistically described.Results The independent risk factors for infection at 3th month after liver transplantation included the operative time ≥600 min [P =0.003,odds ratio (OR) =9.996,95 ％ confidence interval (95 ％ CI),2.221-44.981],intensive care unit (ICU) ≥6 days (P =0.010,OR =6.306,95％ CI =1.563-25.437),Child-Pugh grade of C (P =0.023,OR =6.298,95％ CI =1.294-30.659).Of the 112 liver transplant recipients,59 had an infection (52.68％),and 168 stains of pathogens were isolated.The positive rate of the specimens was highest in sputum,followed by bile,ascites,drainage and catheter end,blood,deep vein catheter,middle urinary,pleural effusion and peripherally inserted central catheter (PICC).The detectable rate of gram-negative bacteria,gram-positive bacteria,fungi and viruses was 46.43％ (78 strains),29.76％ (50 strains),18.45％ (31 strains),and 5.36％ (9 strains) respectively.Infection occurred mainly within 1 month after surgery,accounting for about 80.36％ (135 strains),especially at 1st week after surgery,accounting for about 34.52％ (58 strains).Gram-positive bacteria had a higher drug resistance rate,including penicillins,macrolides,aminoglycosides,quinolones,linamides,etc.especially in the highest rate of Enterococcus faeciurr.Gram-negative bacteria were individualized based on the different strains of the bacteria,and they were relatively low in the resistance of the carbapene.Conclusion Infection is one of the most common complications after liver transplantation.To reduce the incidence of infection after liver transplantation,efforts should be made to shorten the duration of operation and ICU stay time,improve the basic nutritional status of recipients,and enhance monitoring of the recipient's infection after liver transplantation,to further increase the survival rate of postoperative liver transplantation recipients and improve the quality of life.
