简介：厦门，一个足以让人一见倾心的城市．多少人为之向往．为之奋斗然而．厦门抬高落户门槛新政策的出台．无疑于一颗重磅炸弹落在了厦门岛内．引起了业界及消费者的诸多争议。我们且不去论这些观点的对锚与否，至少它反映的是众多开发商与消费者的心声。直至目前为止，令大家最为关注的焦点．恐怕非“房价”莫属了。据业内人士分析，从长远来看，厦门房价仍然走高。因为厦门是块土地开发一块少一块的地方．特别是岛内“僧多粥少”、土地的供求严重失衡的情况下，土地的招标、拍卖挂牌出让，它必然拉动了地价的上升，地价的大幅上升也就必然使厦门商品房房价上升。

简介：AbstractVascular access is the lifeline of hemodialysis patients. There are great differences in the establishment and use of vascular access in different countries and regions around the world. We believe that on the basis of good evaluation and planning, it is recommended that hemodialysis patients choose native arteriovenous fistula first. In view of the new progress of vascular access views domestic and international at home and abroad in recent years, we organized experts to recommend the establishment and maintenance of arteriovenous fistula (AVF) for the Chinese population, including preoperative evaluation and planning of the establishment of AVF, AVF surgery, perioperative drug intervention measures and postoperative maintenance, and put forward suggestions for future research directions. The recommendations in this consensus are general and clinicians need to make treatment decisions based on the actual situation.

简介：AbstractChronic subdural hematoma (CSDH) is a chronic space-occupying lesion formed by blood accumulation between arachnoid and dura mater, which is usually formed in the third week after traumatic brain injury. Surgical treatment is usually the first choice for patients with CSDH having a significant space-occupying effect. Most of the patients showed good results of surgical treatment, but still some patients had a postoperative recurrence (the recurrence rate was up to 33%). Because CSDH is often seen in the elderly, patients are weak and have many basic diseases. The risk of surgical treatment is high; serious complications and even death (the death rate is up to 32%) can often occur. The overall good prognosis rate of patients aged more than 90 years is 24%. The drug treatment can provide a safe and effective treatment for elderly patients who are weak, intolerable to surgery, or failed in surgery. Low-dose and long-term use of atorvastatin (20mg/d) is suggested for continuous treatment for at least 8 weeks, while low-dose and short-term use of dexamethasone can improve the therapeutic effect of atorvastatin on CSDH. Patients should undergo CT or MRI scanning at least one time within 2 weeks after the start of drug treatment.

简介：AbstractMeningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.
