In TCM,sui is divided into brain,spinal cord and bone marrow,etc.They are related to each other closely,stem from the kidney essence and are all connected with sea of sui,which is called fan-sui relation.Recent researches demonstrated that not only brain but also other sui can vary before or after brain damage,which may be a predictor of brain disease,or played an important role in the recovery of brain function.These achievements proved the possibility of fan-sui relation.Further research on the biological mechanism and application of fan-sui relation could:reveal the essence of 'kidney storing essence and generating sui'in TCM better and develop the new idea of the pathological mechanism of brain diseases;enhance preventive consciousness and construct the new preventive system of brain diseases characterized by TCM;help finding new methods or appropriately combine current methods to treat brain diseases.The new viewpoint can provide a chance to develop a new research field of brain diseases and improve the preventive and treatment system of brain diseases.

Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.

Objective To analyze the pitfalls of 18F fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET-CT) scan in the diagnosis of 60 patients of tuberculosis mimicking malignancy.Methods The study included 60 patients with PET-CT diagnosis of probable malignancy.Fifty patients were proved to be tuberculosis by pathological examinations and 10 were diagnosed by clinical followup.The images of whole body were acquired at 60 min after administration of 222-555 MBq 18F-FDG.The PET-CT imaging characteristics and clinical data,including lesion size,distribution,standardized uptake value (SUV) were retrospectively analyzed.After the whole body scan of PET-CT,each patient had a chest spiral CT scan for detailed observation of lung lesions.Contrast enhanced CT (CECT) was performed in 8 patients.Results (1)Thirty patients were misdiagnosed as lung cancer,14 patients as malignant lymphoma,6 patients as malignant mesothelioma,3 as intestine carcinoma,2 as bone malignancy,1 patient as hepatocarcinoma,spleen malignancy,ovarian cancer,laryngocarcinoma and nasopharyngeal carcinoma respectively.(2) 90.9％ (20/22) of patients showed normal level of serum CEA and 100％ (13/13) of patients showed normal level of CA199.Increasing serum CA125 was found in all patients (6/6) with activeTB patients accompanied with ascites,pleural fluid and (or) pericardial effusion.(3) 93.3％ (28/30)active tuberculosis showed accumulated 18F-FDG which was incorrectly interpreted as malignancy.The most common sites of TB lymphadenopathy were bilateral cervical tissues,which was accounted for 85.7％(12/14).CECT revealed characteristics of peripheral enhancement and central necrosis in tubercular lymphadenopathy,which was 87.5％ (7/8).Conclusions The diverse manifestations of TB on imaging and high uptake of 18F-FDG on PET imaging result in misdiagnosis of malignancy.It is important for radiologists and nuclear medicine physicians to identify the common imaging features and patterns of TB to make a correct diagnosis.Integration of reconstruction HR CT,PET-CT and lab examinations may improve the diagnostic accuracy.

Objective To study the effects of Qingzao Runfei Huazhuo Xingxue decoction (QRHXD) on inflammatory reaction and histopathology in mice with PM2.5-induced pulmonary injury, and to approach the possible mechanism of prevention and treatment of traditional Chinese medicine on lung injury induced by haze.Methods Fifty healthy male C57BL/6 mice were randomly divided into five groups (n = 10): namely control, PM2.5, PM2.5+ low-, moderate-, and high-dose groups. The PM2.5 suspensions at a dosage of 40 mg/kg was respectively given to mice by the nasal instillation for reproduction of mouse model of lung injury induced by PM2.5, and the mice in control group were given the same volume of normal saline. The mice in PM2.5+ low-, moderate-, and high-dose QRHXD groups were given 15, 25, 50 mL·kg-1·d-1 QRHXD by oral perfusion daily for consecutive 21 days at the next day of model reproduction (the QRHXD included: Pear 75 g,Bulbus Fritillariae Cirrhosae 10 g, Radix Stemonae 8 g,Rhizoma Pinelliae 8 g,Radix Platycodi 6 g, Aster 10 g, Almond 5 g, Lily 6 g, Rhodiola 4 g, Lotus 3 g,Fructrs Liquidambaris 6 g,Radix Paeoniae Rubra 5 g, Semen Cassiae 6 g). The mice in control and PM2.5 groups were given equivalent volume of normal saline respectively. After treatment for 21 days, the mice were sacrificed, and the left lung was harvested for bronchoalveolar lavage, and the bronchoalveolar lavage fluid (BALF) was collected for determination of levels of acid phosphatase (ACP), alkaline phosphatase (AKP), lactic dehydrogenase (LDH), and albumin (ALB). The right lung was harvested for histopathology observation under light microscope using hematoxylin and eosine (HE) staining.Results After intranasal instillation of PM2.5 suspension, the levels of ACP, AKP, LDH, and ALB in PM2.5 group were significantly higher than those in control group [ACP (U/L): 3.9±0.4 vs. 1.7±0.3, AKP (U/L): 9.0±1.5 vs. 4.8±0.3, LDH (U/L): 416.7±44.4 vs. 112.5±20.3, ALB (mg/L): 198.7±32.4 vs. 65.8±21.3, all P < 0.05]. Under light microscope, the PM2.5 particles were collected, the alveolar septa were thickened, and the inflammatory cells in the alveolar cavity and pulmonary interstitium were found. On the contrary, after administration of QRHXD, a significant reduction of biochemical indexes was found, which showed a dose-dependent manner. The parameters of PM2.5+ high-dose QRHXD group were significantly lower than those in PM2.5 group [ACP (U/L): 2.1±0.8 vs. 3.9±0.4, AKP (U/L): 5.3±1.4 vs. 9.0±1.5, LDH (U/L): 146.6±29.8 vs. 416.7±44.4, ALB (mg/L): 88.5±26.7 vs. 198.7±32.4, all P < 0.05]. At the same time, the pathological changes in lung tissue were better with the increase of the dose.Conclusions QRHXD can reduce the pulmonary inflammatory response and tissue damage caused by PM2.5, with the increase concentration of Chinese medicine, and the effect is more obvious. This may be related to the immune response of the human body to regulate inflammatory mediators, which provide basis for the treatment of pulmonary injury induced by PM2.5.

Objective To explore the effect of different delivering methods on the pelvic floor function in vaginal delivery by transvaginal three-dimensional ultrasound.Methods Eighty-four patients delivered transvaginal were classified into three groups according to the mode of delivery (perineal integrity group [n=32],episiotomy group [n=30] and forceps delivery group [n=22]).The hiatal images at resting,Valsalva,levator ani muscle maximum contraction were obtained and compared in three groups.Results There were no differences between perineal integrity group and episiotomy group in hiatal diameter and area (P＞0.05).There were significantly differences between perineal integrity group and forceps delivery group in hiatal diameter,area and change in hiatal area from rest to pelvic floor muscle contraction and from rest to Valsalva (all P＜0.05).Conclusion The injury of the pelvic floor of forceps delivery group is bigger than perineal integrity.And episiotomy is no significant difference with pelvic floor function injury.
