Williams syndrome is a rare disease caused by 1.5 ～ 1.8 Mb gene deletion in the chromosome 7q1 1.23 region,with autosomal dominant inheritance.The incidence is about 1/10 000.It involves the cardiovascular system,nervous system,endocrine system and so on,and is most likely to cause damage to the cardiovascular system.The mortality of sudden cardiac death in patients with Williams syndrome is higher than that in healthy population.At present,suspected patients were screened by Lowery score and the American pediatrics score,then were evaluated by imaging examination and were diagnosed by gene detection.The main therapy is symptomatic treatment.Therefore,it is important to ensure an accurate diagnosis and prompt treatment.In the article,the research progress of the clinical diagnosis,gene diagnosis,gene therapy and prognosis is reviewed.

Objective:To discuss the relationship between serum advanced oxidation protein products (AOPP)and cystatin C with the early preeclampsia pregnancy outcome.Methods:Clinical data of 75 patients received treatment and labor at our hospital from 2011 to 2013 was retrospectively analyzed.The control group included 60 normal pregnant women who received prenatal examination in our hospital at the same time.The difference in cystatin C and AOPP level of the patients with preeclampsia and the normal group was compared.The clinical data and the adverse pregnancy outcome of the patients with preeclampsia in different severity and different outcome of pregnancy were compared.Results:A total of 135 patients were retrospective analyzed ,including 75 in observe group and 60 in control group.The SBP level in the patients with preeclampsia is obviously higher than in the normal group .The level of SB,UA,Cr and AOPP in the patients of mild group is obviously lower than in the severe group.The incidence of oligohydramnios , placental abruption,fetal growth restriction and HELLP syndrome in the patients of mild group was obviously lower than in the severe group .The differences were statistically significant.The level of cystatin C,UA,Cr and AOPP in the patients of adverse pregnancy outcome were obviously higher than in the group of good outcome of pregnancy.Conclusion:The cystatin C and AOPP level of the early preeclampsia patients is obviously increased and it has significant correlation with the pregnancy outcome in patients .

This paper reviews the advances concerning the diagnosis and treatment of carpal collapse. Systematic study on carpal collapse was launched only two decades ago. The improved roentgenologic diagnosis has deepened our understanding of the disorder. Its classification has helped doctors conduct objective follow ups of the progress and prognosis of the disease. And the related biomechanical research has made clear mechanism of the collapse which can serve as an important basis for choice of operative methods. The various partial carpal arthrodesis, of which the commonest is four corner arthrodesis, and proximal row carpectomy are proved to be effective in relieving most symptoms and ending the continuation of collapse, so they have become major treatment methods for the disease. But operative methods have to be chosen in the light of detailed conditions of radiocarpal and midcarpal joints. The silicon arthroplasty has been abandoned due to its serious complications.

In order to get more nutrition from outside the erythrocyte,new channels were induced by malaria par-asite.These channels play an important role in physiology of the parasitized cell.They are of interest both as potential targets in their own right and as potential drug targeting routes capable of mediating the entry of cytotoxic drugs into the app-ropriate compartment of the infected cell.It is hoped that this new anti-malarial strategy will help to create a sustainable anti-malaria-drug-development portfolio for the treatment of malaria.

BACKGROUND:Periodontal ligament stem cels are one of the ideal seed cels in periodontal tissue regeneration. Sources, biological characteristics and influential factors of periodontal ligament stem cels have been an issue of concern. OBJECTIVE:To review the biological characteristics and functional factors of periodontal ligament stem cels as wel as relevant research status and progress in regenerative medicine, and to discuss the relevant application prospect and existing problems, thereby providing theoretical and experimental basis. METHODS:PubMed and Wanfang databases were searched by the first author for articles related to differentiation and proliferation of periodontal ligament stem cels published from 2002 to 2015. The key words were “periodontal ligament stem cel, periodontal tissue, proliferation, differentiation” in English and Chinese, respectively. Finaly, 47 articles were included in result analysis. RESULTS AND CONCLUSION:Periodontal ligament stem cels have the ability of differentiating into fibroblasts, adipocytes, chondrocytes and cementum. Cel growth factors play an important role in the proliferation and differentiation of periodontal ligament stem cels. Fibroblast growth factor, vascular endothelial growth factor and insulin-like growth factor can promote the proliferation of periodontal ligament stem cels. Application of stem cel biofilm as a carrier material can effectively guide periodontal tissue regeneration. Isolation, culture and influential factors of periodontal ligament stem cels should be further improved. Combined application of stem cels, biofilms and growth factors is expected to achieve the desired periodontal tissue regeneration, which is the focus of future research.

Objective To discuss the application and effect of sufentanil combined with propofol on painless gastroscopy anesthesia.Methods In the fourth people's hospital of Zhejiang in April 2014-June 2016,94 cases treated with painless gastroscopy I were randomly divided into two equal groups.Anesthesia group A were anaesthetized with fentanyl and propofol,sufentanil and propofol for anesthesia group B.The anesthetic effect,the time of consciousness disappearance,eye opening time,recovery time of orientation,the dosage of propofol in the two groups were compared.The mean arterial pressure,heart rate and adverse reaction rate in the two groups were compared.Results The anesthetic effect in the anesthesia groupB is significant better than that in the anesthesia group A(P<0.05).Compared with the anesthesia groupA,the time of consciousness disappearance,eye opening and orientation recovery is shorter in the anesthesia groupB(P<0.05),The difference of the mean arterial drug Pressure and heart rate is not significant in the two groups before medication.After medication and wake up,compared with the anesthesia group A,the mean arterial pressure,heart rate fluctuation is smaller,and the adverse reaction rate is lower in the anesthesia group B,(P<0.05).Conclusion It is effective which sufentanil combined with propofol used in anesthesia in painless gastroscopy,It can stable vital signs of patients during operation,,work quickly,restore consciousness rapidly,and contribute to reduce complications,and is worthy of promotion.

OBJECTIVE:To investigate the hemostatic effect and safety of hemocoagulase in radical gastrectomy.METHODS:60 cases with gastric cancer were divided on average into 2 groups.Therapy group received hemocoagulase 2 KU during and after operation,and control group received dicynone 0.5 g and aminomethylbenzoic acid 0.2 g during and after operation.Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation were observed.The value of D-dimer was monitored after operation.RESULTS:Intraoperative blood loss and amount of blood drainage at 6 h and 24 h after operation in therapy group were less than in control group (P

We detected varicella-zoster virus (VZV) DNA sequences in bullous lesions and skin biopsies obtained from healed skin lesions in 16 patients with herpes zoster using polymerase chain reaction. A 385 bp VZV DNA fragment was found in all the bullous lesions and in two of six biopsies from the skin lesions healed within two months. No VZV DNA was found in the skin lesions two months after healing in 10 cases of herpes zoster. VZV DNA may be detected at the sites of resolved herpes zoster lesions within short duration.

In the course of patient care, it may occur that doctors and patients have unbalanced grasp of medical information, which directly affects the building of doctor-patient trust and patients'evaluation of medical effects. Instrumental methods for building and enhancing doctor-patient trust include mainly the use of relative networks or the presentation of favors while affective methods chiefly include mutual respect and the promotion of friendly relations via communication. The rebuilding of doctor-patient relationship of trust, however, can be approached from the following seven perspectives: ①establishing and perfecting the system of rendering information accessible to the public; ②raising the managers'awareness of trust; ③building an atmosphere of trust acceptable to the entire staff members; ④accepting the restraint of standards and morality; ⑤rendering information accessible to the public in a realistic way; ⑥taking the initiative in clearing up doubts and performing the obligation of notification; and ⑦perfecting the mechanisms of supervision and reward.

Nonglomerular synapses in the neuropil of the substantia gelatinosa of adult ratspinal trigeminal nucleus were subjected to electron microscopic examination. Nonglomerular synapses in the substantia gelatinosa were associated with four main types of axonal terminals. On the basis of vesicle shapes, these were classified as round vesicle, elongate vesicle, pleomorphie vesicle, and dense cored vesicle terminals. The category of round vesicle terminals could be subdivided into large round vesicle terminals and small round vesicle terminals according to their different size of synaptic vesicles. Nonglomerular synapses included four types, i. e. axodendritic, axo-axonic, dendro-dendritic and dendro-axonic synapses. Of these, the majority of synapses were axodendritie. The functional significance of the classification of these synapses and their axonal terminals had been discussed.
