Biomaterials are commonly applied in regenerative therapy and tissue engineering in bone.Generally,nanoparticles interact distinctively with bone cells and tissue,depending on their com-position,size,and shape.Therefore,detailed analyses of nanoparticle effects on cellular functions have been performed to select the most suitable candidates for supporting bone regeneration.This review will highlight potential nanoparticle applications in bone.We found that mesenchymal stem cells (MSCs) display exceptional regenerative potential.The delivery of genetic material with nanoparticulate carriers offers the possibility of overcoming certain disadvantages of standard protein delivery approaches.Moreover,nanoparticles are already clinically applied in cancer treatment.Thus,corresponding efforts could lead to new therapeutic strategies to improve bone regeneration or to treat bone disorders.

OBJECTIVE:To study the general pattern and characteristics of adverse drug reactions(ADR) induced by tinidazole.METHODS:Tinidazole-induced ADR cases reported in the internal pharmaceutical journals retrieved from Jan.1994 to Jun.2006 were analyzed statistically.RESULTS:The ADR induced by tinidazole were diversified in clinical manifestation,but allergic response was the most common type,followed by the lesion of nervous system and digestive system etc.CONC-LUSION:Clinicians should attach great importance to the ADR induced by tinidazole.

Objective To validate scientificalness,practicability and useful values in medical care of Zhang-Lu index(ZLI).Me-(thods) ZLI=weight(g)+250/height(cm)?head circumference(cm)?2 was computed and compared with the conventional body weight for gestational age based data of body height,body weight and head circumference measured from 858 neonates in Benxi.Results The ZLI of the first 3 days of fullterm appropriate for gestational age(AGA) was higher than reference from national neonatal physical growth science research association.The difference was significantly(P

Abstract: Objective　To report the clinical characteristics and genetic test results of two children with neurofibromatosis type 1 (NF1), and to provide reference for the comprehensive diagnosis-treatment and follow-up plans of NF1 patients based on the existing diagnosis and treatment progress of NF1. Methods　Two children with NF1 admitted to the Department of Children's Medicine, Haikou people's Hospital in May and June 2022 were selected to analyze the clinical data of their clinical manifestations, laboratory examination, genetic test results, diagnosis and treatment and follow-up retrospectively. Results　Two children had typical clinical manifestations, such as café-au-lait spots, axillary freckles, intraocular iris hamartoma. Venous blood was collected from case 1 and his parents for NF gene test, and a new mutation of c.4084C>T in the NF1 gene was found, and their parents did not have the pathogenic gene; the venous blood of the children in case 2 was tested for whole-exome gene analysis, and a heterozygous nonsense variant c.910C>T:p.R304 on the NF1 gene was found, , which was verified by Sanger sequencing to be inherited from his mother, his mother has café-au-lait spots and brain glioma, and has undergone surgery to remove the brain glioma, but has not undergone chemoradiotherapy or targeted therapy. No neurological malignancies were detected in either of the two children at follow-up until July 2022. Conclusions　The clinical manifestations of NF1 are relatively typical, genetic testing is conducive to determine its classification, and regular follow-up review can help to detect and treat malignant tumors early, thus improving the patient's quality of life.

AIM: Using functional magnetic resonance imaging, to inspect v sual cortex physical reactions stimulated by rotating grating, and to its components. METHODS: On 1.5T MR scanner, GRE-EPI imaging sequence was carried on 9 h discover ealthy volunteers, the visual cortex response data were processed after delinearation by SPM99.RESULTS: Different components of rotating grating excited different areas of the visual cortex. Dramatic response in the central part of the occipital lobe, which was related to white light stimuli, located at primary visual cortex. Response area in bilateral Broadaman 19 areas was related to vision-motion function. And weak response area in the central part of the occipital lobe was related to shape perception.CONCLUSION: Rotating grating conclude plenty of visual information, and it excites different areas of the optic center as a stimuli. fMRI is a valuable equipment to study the physiology of visual cortex.

OBJECTIVETo observe the clinical effectiveness of Qilin Pills combined with sertraline in the treatment of secondary non-consolidated kidney qi premature ejaculation (PE).

METHODSA total of 120 patients with secondary non-consolidated kidney qi PE were randomly assigned to groups A (aged [35.5 ± 5.4] yr), B (aged [36.2 ± 5.7] yr), and C (aged [35.2 ± 5.3] yr) in the ratio of 1:1:1 to receive Qilin Pills (once 6 g, bid), sertraline (once 50 mg, qd), and Qilin Pills plus sertraline, respectively, all for 4 weeks. The intravaginal ejaculatory latency time (IELT) and PE diagnostic tool (PEDT) scores were obtained before and after medication and at 1 month after drug withdrawal, and comparative analyses were made among the three groups of patients.

RESULTSThe IELT was dramatically prolonged in groups A, B, and C after treatment ([3.23 ± 1.84], [3.87 ± 2.43], and [5.92 ± 3.11] min) and at 1 month after drug withdrawal ([1.85 ± 1.27], [1.52 ± 1.06], and [ 4.26 ± 1.88 ] min) as compared with the baseline ([0.88 ± 0.45], [0.84 ± 0.47], and [0.85 ± 0.50] min) (P < 0.01), even longer in group C than in A and B (P < 0.01). The PEDT scores of the three groups were 5.1 ± 1.8, 4.9 ± 1.7, and 3.8 ± 1.2 after treatment and 8.2 ± 2.4, 8.1 ± 2.4, and 6.5 ± 2.1 at 1 month after drug withdrawal, significantly improved in comparison with 13.2 ± 3.2, 12.8 ± 3.1, and 13.1 ± 3.4 before treatment (P < 0.01), even more significantly in group C than in A and B (P < 0.01).

CONCLUSIONQilin Pills combined with sertraline has a definite efficacy in the treatment of secondary non-consolidated kidney qi PE and therefore deserves wide clinical application.

Objective To evaluate the application of duct endoscopy in the diagnosis of breast diseases characterized by nipple discharge.Methods One hundred and sixty-nine consecutive cases from October 2003 to September 2004 who had duct endoscopy for nipple discharge were reviewed and followed up.Results Of 169 cases,79 ductitis,62 intraductal papilloma,9 intraductal carcinoma in situ,19 without breast diseases were diagnosed under duct endoscopy.During following up,the diagnostic accuracy of intraductal papilloma and intraductal carcinoma in situ with duct endoscopy was 89.8%(44/49) and 55.6%(5/9),respectively.There was only one patient who had breast pain and mild skin redness which was cured with oral antibiotics for 3 days.Conclusion Duct endoscopy is an only technique to explore the etiology for duct discharge under vision.It is direct,safe and effective,with a high accuracy.

Objective To provide decision-making information for the spread of techniques that improve the quality of neonates. Methods A systematic study was made of the political, technical, economic and social viability of neonatal disease screening in China by means of economic and policy evaluation, sociological analysis, and statistical analysis. Results Neonatal disease screening was conducted in 29 provinces throughout the country. However, there was a great difference between the provinces in screening coverage. In order to strengthen control, 16 provinces issued methods or regulations concerning neonatal disease screening. Since the Ministry of Health did not issue relevant control methods that would standardize the responsibilities of the organizations undertaking the screening, problems affecting the safety and effectiveness of neonatal disease screening became increasingly prominent. Conclusion It is necessary and viable to conduct neonatal disease screening in China. But macro control of the work by the government needs to be reinforced. The Ministry of Health ought to issue as soon as possible methods for controlling neonatal disease screening and relevant technical criteria. At the same time publicity of the work needs to be strengthened in society so as to give it impetus throughout the country.
