Objective To analyze the situation of the intellectual development of children between 0 to 18months.Methods Using Denver Developmental Screening Test(DDST),1 064 children aged between 0 to 18 months in four items:their indicidual and social reaction ability,subject-touching reaction ability of fingers,and speaking ability as well as movement ability were tested,each itern had 2 kinds of tests and here only need to test one kind which is shown on the left part of DDST.Every example need to understand the pregnancy history,family history,birth of children,past history,parents'jobs and education level.The measured results were calculmed,about the ages of which 50%examlnation could pass in each test itern and 90%could pass,and compared with tested children in Denver.Results The passing rate of same item would be increased as age increases.the passing rate would be different between different test items in the sslne age,and the more difficult the item,the lower the passing rate.The common trend of children's intellectual development Was in accordance with that of Denver children,whereas there were age differences that pass certain items.Conclusion As a screening way of infants'intellectual tests,DDST had universal significance.Lacking scientific education was an important cause of mental retardation in children.

GLP-1 has a variety of anti-diabetic effects. However, native GLP-1 is not suitable for treatment of diabetes due to its short half-life (t½, 2-5 min). Exendin-4 is a polypeptide isolated from lizard saliva, which can bind to GLP-1 receptor, produce physiological effects similar to GLP-1, t½ up to 2.5 h, therefore, we developed a long-lasting GLP-1 receptor agonists and GLP-1-exendin-4 fusion IgG4 Fc [GLP-1-exendin-4/ IgG4(Fc)]. We constructed the eukaryotic expression vector of human GLP-1-exendin-4/IgG4(Fc)-pOptiVEC- TOPO by gene recombination technique and expressed the fusion protein human GLP-1-IgG4 (Fc) in CHO/DG44 cells. The fusion protein stimulated the INS-1 cells secretion of insulin, GLP-1, exendin-4 and fusion protein in CD1 mice pharmacokinetic experiments, as well as GLP-1, exendin-4 and fusion protein did anti-diabetic effect on streptozotocin induced mice. Results demonstrated that the GLP-1-exendin-4/IgG4(Fc) positive CHO/DG44 clones were chosen and the media from these positive clones. Western blotting showed that one protein band was found to match well with the predicted relative molecular mass of human GLP-1-exendin-4/IgG4(Fc). Insulin RIA showed that GLP-1-exendin-4/IgG4(Fc) dose-dependently stimulated insulin secretion from INS-1 cells. Pharmacokinetic studies in CD1 mice showed that with intraperitoneal injection (ip), the fusion protein peaked at 30 min in circulation and maintained a plateau for 200 h. Natural biological half-life of exendin-4 was (1.39 ± 0.28) h, GLP-1 in vivo t½ 4 min, indicating that fusion protein has long-lasting effects on the modulation of glucose homeostasis. GLP-1-exendin-4/IgG4(Fc) was found to be effective in reducing the incidence of diabetes in multiple-low-dose streptozotocin-induced diabetes in mice, longer duration of the biological activity of the fusion protein. The biological activity was significantly higher than that of GLP-1 and exendin-4. GLP-1-exendin-4/IgG4(Fc) has good anti-diabetic activity. It can be used as a long-acting GLP-1 agonists.

Orthodox Manual of External Diseases is a book giving an exhaustive description on various kinds of external and surgical disease,written by CHEN Shi-gong(1617),the author pay more attention to concept of wholism and syndrome differentiation.He provided the original view on the treatment of disease that combine internal with external therapy,needle with herbs.① All the external symptoms originates from internal causes and all diseases arisen from pathogenetic fire.Carbuncle definitely caused by visceral disorders,addiction to greasy diet,overstrain and exhaustion of sexual activities.② Based on occurrence and development of surgical disease,currency of ebb and flow between pathogenic factors and health qi,he provided three therapeutic methods for surgical disease including resolving,expelling from within,and reinforcing.③ He created and improved some surgical operation and provide the new therapeutic way that expelling the pathogenic factor by opening and drainage.④ He also believed that invigorating and regulating spleen and stomach,harmonizing qi and blood should be put in the first place when treating disease.

Objective To investigate and compare the perception of communication difficulties by mainstreaming students with hearing impairment and that of their peers.Methods The children’s version of the Abbreviated Profile of Hearing Aid Benefit (APHAB) was used to measure perceived communication difficulty in various daily situations.Results There was significant difference between the perception of mainstreaming students and that of their peers for the background noise(BN) subscale questions.Conclusion In order to improve the communication ability of the students with hearing impairment, it is critical to educate one of their important communication partners—their peers, about the hearing loss and its effect on communication, especially under the situation of background noise.

Objective To observe the clinical effect of herbal decoction Sishen Jian on acute osteoarthritis of knee joint.Methods The 60 osteoarthritis cases in the attack stage were randomized into treatment group(30 cases)and control group(30 cases).The treatment group was given the decoction Sishen Jian and Diclofenac Sodium Sustained Release Capsules and the control group was given the capsules only.Two weeks made one course of treatment.Before and after treatment,the symptoms such as pain and morning stiff- ness,the signs including joint swelling and tenderness,and the erythrocyte sedimentation rate(ESR)and C reactive protein were ob- served for comparison.Results The total effective rate of the treatment group and control group was 96.66% and 53.26% respec- tively.The difference of two groups was significant(P

Bacillus subtilis is a good producer of mannanase.This is the first study to investigate mannanase production under solid state fermentation(SSF) by Bacillus subtilis.Bacillus subtilis WY34 was used for the production of extracellular mannanase in the SSF of wheat bran.The highest mannanase activity was 7,650 U/g dry matter when the following conditions were used: wheat bran 5g,initial moisture content 71%,Tween-80 1%,konjac powder 0.4 g,initial pH 7.0,incubation temperature 50 ℃.Enzyme production was increased 178% after optimization.

The FDA approved a total of 37 new drugs in 2022, including 22 new molecular entities and 15 new biological products. This is the year with the lowest number of new drugs approved by the FDA since 2017. Among these approved drugs, 21 new drugs belong to the "first-in-class" category, accounting for 56% of the total approved drugs, which is the highest ratio in the past 10 years. Among the drugs approved in 2022, there are 5 small molecule kinase modulators, including the tyrosine kinase 2 (TYK2) allosteric inhibitor deucravacitinib, the first oral pyruvate kinase (PK) activator mitapivat, the Janus kinase 1 (JAK1) selective inhibitor abcrocitinib, the JAK2 selective inhibitor pacritinib and the broad-spectrum fibroblast growth factor receptor (FGFR) inhibitor futibatinib. This review briefly describes the discovery background, research and development process, synthesis routes and clinical efficacy and safety of small molecule kinase modulators approved by the FDA in 2022, hoping to provide ideas and methods for further research on kinase modulators.
