Objective To explore the causes of congenital hypothyroidism by single photon emission computed tomography(SPECT) thyroid imaging.Methods Nineteen cases with congenital hypothyroidism were collected,and SPECT thyroid imaging was performed 15 minutes late after injected 99m TcO_ 4- 18.5-37.0 MBq.Results Five cases were found with normal glands,1 case with enlarged thyroid, 2 cases with enlarged thyroid and increased radiation,4 cases with ectopic thyroid,4 with a hypogenetic thyroid,and the last 3 cases showed no thyroid imaging.Conclusions The causes of congenital hypothyroidism can be found by SPECT thyroid imaging,which is important to the diagnosis of congenital hypothyroidism combined with detection of T_3,T_4,TSH.

Objective To investigate the effects of mindfulness training on cancer related fatigue (CRF) in patients with breast cancer .Methods Two hundreds young and middle‐aged patients with breast cancer receiving chemotherapy in our hospital from January to June 2015 were divided into the observation group and control group ,100 cases in each group .The control group was given the routine nursing ,while on this basis the observation group was given the mindfulness training .The cancer related fa‐tigue status was evaluated according to the CFS scale .The CFS various dimensions and total fatigue scores before and after inter‐vention were compared between the two groups .Results The fatigue status existed in most of patients with breast cancer after chemotherapy ,the occurrence rate of CRF was 97 .0% ,which was dominated by moderate fatigue ,followed by mild fatigue ,severe fatigue was minimal ;the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the second time of chemothera‐py had no statistically significant differences between the two groups (P>0 .05);in the fourth and sixth time of chemotherapy ,the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the observation group were significantly lower than those in the control group ,the differences were statistically significant (P<0 .05) .Conclusion The mindfulness training interven‐tion can relieve the fatigue status and improve the living quality of the patient .

Objective To evaluate the diagnostic value of 99mTc-dimercaptosuccinate acid(DMSA) renal cortical scintigraphy for the identification of distinguishing between upper urinary infection(UUTI) and lower upper urinary infection(LUTI).Methods Two hundred and seventy-five children (111 males,164 females)ranging from 44 days to 15 years old,presented with urinary tract infection underwent 99mTc-DMSA renal cortical scintigraphy.The images were scored as normal (indicating LUTI) and abnormal (indicating acute pyelonephritis or renal scarring).Results Of 275 children with UTI,95 cases had normal images diagnosed as LUTI,41 males,54 females;and 180 cases had abnormal images,70 males,110 females.One hundred and seventy-four cases were diagnosed as acute pyelonephritis,6 cases were diagnosed as renal cortical scars,56 cases were single renal involved and 118 cases were both renal involved,and 22 cases repeatedly underwent renal cortical scanning after therapy.Sixteen of 18 cases with acute pyelonephritis completely recovered normal or obviously ameliorated after 0.5 to 2.0 years,2 cases did not show any improvement after 0.5 to 1.5 years,4 cases with renal scarring,and showed little change on repeated images after 1.0 to 1.5 years.Conclusions The 99mTc-DMSA renal scintigraphy is very useful in differentiating the children with urinary tract infection.It also can be used to determine the extension,degree and nature of UUTI,and might play an important role in the treatment and follow-up observation in children with UUTI.

Oral iron is a commonly used preparation for the treatment of iron deficiency and iron-deficiency anemia in children, but its undesirable taste has become a major factor affecting clinical adherence to the medication. No studies have been conducted to evaluate the palatability of oral iron supplements. Thirteen representative oral iron supplements were selected to evaluate the palatability of oral iron supplements from different perspectives of in vivo and ex vivo by combining the electronic tongue (e-tongue) test, FaceReader facial expression analysis technology and taste interviews. E-tongue test results showed that iron dextran granlues were closest to odorless potassium chloride solution, basically free of bitterness and astringency, which was superior to the other products. FaceReader facial expression results showed that 58.7% of the subjects valued iron dextran granlues for their emotional efficacy higher than that of iron proteinsuccinylate oral solution. Among 43 participants aged ≥ 5 years, the taste preference for iron dextran granlues was 83.7%, and 83.7% of participants chose to take iron dextran granlues again. This study found that iron dextran granlues have a better taste and their flavor is more popular among children, which provides a reference for pediatric clinical use of oral iron supplementation preparations and a new idea for the evaluation of palatability of medications for children. This in vivo palatability evaluation is an investigational clinical trial that was approved by the Institutional Review Board of the Beijing Children's Hospital (No. 2021-149-Y).

The mainly antigenic sites for the adenovirus neutraliation are present on Loop1 and Loop2 of hexon.Majority research were focus in the human adenovirus.Little was known on infectious canine hepatitis virus (ICHV), which was also called canine adenovirus typeⅠ.Here,ICHV (the isolated strain) DNA was isolated and purified from the cultured MDCK cells.The Loop1 and Loop2 fragments were amplified by polymerase chain reaction(PCR) method,and then was connected by ligase T4.The target fragment was then connected with vector pET28a.The nucleotide sequence ecoding Loop1 and Loop2 was determined.The nucleotide sequence identity of Loop1 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 100%, 100% and 83.8%, and the nucleotide sequence identity of Loop2 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 88.1% , 88.1% and 99.3%, and amino acid identity is 93.6%, 93.6% and 98.6%.The recombinant Loop protein was expressed in E.coli and was approximately 36kDa in size,and then was purified. Then BALB/c mice were injected subcutaneously in the back and armpit with the recombinant Loop protein.The anti-ICHV antibody titers of immunized serum was tested by indirect ELISA and the titers were up to 1:320.Western blot demonstrated that immunized sera could specifically combine with ICHV. The research laid a foundation for creating new genetic engineering products of infectious canine hepatitis virus.

Tripterygium wilfordii has exihibited multiple pharmacological activities, such as anti-inflammatory, immune modulation, anti-tumor and anti-fertility. T. wilfordii have been used for the therapy of inflammation and autoimmune diseases including rheumatoid arthritis, immune complex nephritis and systemic lupus erythematosus clinically. However, it is well known that T. wilfordii has small margin between the therapeutic and toxic doses and could cause serious injury on digestive, reproductive and urogenital systems. Among all the organs, liver is one of the most remarkable targets of T. wilfordii-induced toxicities, and the damage is more serious than others. It is generally accepted that T. wilfordii-induced liver injury is a result of the combined effects of toxic elements of T. wilfordii. It is reported in several studies that the mechanism of T. wilfordii-induced liver injury may be related to lipid peroxidation, cell apoptosis and immune damage, and so on. Licorice is one of the most commonly used Chinese herbal medicine, with effects of heat- clearing and detoxicating, anti-inflammatory and hepatoprotective, reconciling various drugs, and so on. Licorice often accompany T. wilfordii in clinical application which can significantly reduce the liver injury induced by T. wilfordii. The attenuated effect is exact, but the mechanism is still a lack of in-depth study. This paper reviews the studies on T. wilfordii-induced liver injury and the related mechanism as well as licorice and other traditional Chinese medicine accompany T. wilfordii to reduce the injury in recent years, so as to provide reference for related research in the future.
