In order to explore the cellular mechanism of antishock effect of anisodamine (654-2), the changes of intramitochondrial magnesium during late hemorrhagic shock were observed. Results showed that there exists a negative correlation between the blood plasma magnesium concentration and arterial blood pressure in shocked animals and at the same time the magneium content of liver mitochondria reduced significantly; 654-2 prevented the decrease of mitochondria magnesium and the increase of blood plasma magnesium, and improved the prognosis of the shocked animals. These results indicate that 654-2 may protect the liver mitochondria of shocked animals at a cellular and subcellular levels.

Objective To investigate the characteristics and diagnostic value of fundus fluorescein angiography(FFA)for familial exudative vitreoretinopathy(FEVR).Methods 34 children(68 eyes)with FEVR and 64 parents(1 28 eyes)were included.All the clients were received examinations of slit-lamp biomicroscopy and indirect ophthalmoscopy.Meanwhile the children were examined by Retcam Ⅱ,the best corrected visual acuity of parents were recorded.The children and their parents were classified according to the ocular findings.Among 68 eyes of children,3 eyes(4.41% )were normal,4 eyes(5.88% )were in stage 1,7 eyes(10.29% )were in stage 2,2 eyes(2.94% )were in stage 3,8 eyes(11.76% )were in stage 4 and 44 eyes(64.71% )were in stage 5.Among 128 eyes of parents,74 eyes(57.81% )were normal,51eyes(39.84% )were in stage 1,1 eyes(O.78% )were in stage 2 and 2 eyes(1.56% )were in stage 5.FFA was performed on the children with RetcamⅡunder anesthesia and on the parents with HR2 in order to observe the FFA characteristics in different stage.Results FFA characte ristics in children included uncompleted vascularization of the periphery,peripheral avascular zone(stage 1);neovascularization and/or peripheral subretinal and intraretinal exudation(stage 2);subtotal retinal detachment with attached foyea (stage 3);subtotal retinal detachment with detached foyea(stage 4)and total retinal detachment(stage 5).FFA characteristics in parents included abrupt cessation of the peripheral retinal capillary network and a peripheral avascular zone(stage 1); abnormal peripheral arteriovenous shunts, neovascularization or exudation(stage 2)and atrophia bulbi(stage 5).Conclusions FEVR in different stage has different FFA characteristics.FFA plays an important role in early diagnosis of FEVR.

With the development of modem tumor diagnostic techniques and therapies, the survival rate of malignant tumor has been remarkably increased. With the increase in survival rate of cancer-beating patients, the chance of tumor metastasis is elevated. Minimally invasive treatment provides a new strategy to the therapy of spinal metastatic carcinoma. Its benefits include smaller surgical wound,, higher efficacy and fewer complications, and thus have a broad application prospects in the field of spinal metastatic tumors. In this article, a general re-view is given on minimally invasive treatments of spinal metastatic carcinoma, as well as the latest progress in the field. It was proposed that the united application of the treatment might be a promising hot spot of tumor therapy.

Tension-free hernioptasty is a major method for treating inguinal hernia, characterizing by less wound, tension-free incision, sample processing, less dissection and separation, mild pain, rapid recovery, and short length of stay. In particular, transabdominal preperitoneal inguinal hernioplasty is considered as the most ideal method at physiologicoanatomical level. However, the effect of patch materials on postoperative recovery is generally ignored for a long time. Recent studies demonstrate that patch weight and mesh diameter are important factors for abdominal wall repairing and reconstruction. Polypropylene patch, characterizing by strong stability, high intensity, great unreactiveness, and sample processing, has become a major material for hernioptasty. However, there are still some problems of clinical application, including that polypropylene patch may induce intensive foreign body reaction and chronic inflammation as well as compliance decreasing of abdominal wall. Therefore, polypropylene patch should be chosen according to patient requirement, i.e., light, soft, and wide-aperture patch, so as to reduce onset of complication. Nerve and ligament tissues could be clearly observed from light and soft patch, and this might and prevent hurt by mistake, improve repairing operability, enhance correct putting of patch, and decrease incidence of pain. Furthermore, the structure was beneficial for in-growth of fiber tissue, longitudinal and transversal movement induced by body position alternation and muscle contraction, and reduction of discomfortableness.

Hand, foot, and mouth disease (HFMD) is a viral infectious disease regarded to be a public-health problem worldwide. Since the 1990s, HFMD began to spread in the Asia-Pacific region (especially in South-East Asia). HFMD outbreaks have occurred in mainland China frequently since 2008, and the morbidity and mortality of HFMD has continued to increase in recent years. In mainland China, enterovirus A serotype enterovirus A71 (EV-A71) and coxsackievirus A16 (CVA16) have been the major pathogens of HFMD during these years. However, the etiological spectrum of HFMD changes with time. This review focuses mainly on the etiological spectrum of HFMD and changes in epidemic patterns in mainland China.

Purpose CT spectroscopy imaging was used in the preoperative differentiation evaluation of renal clear cell carcinoma, to access its malignant degree preoperatively, and to guide the operation treatment. Materials and Methods The spectral characteristics of 40 patients with renal clear cell carcinoma (RCCC) were analyzed retrospectively, all the RCCC patients underwent gemstone spectral imaging (GSI) scans, to obtain spectral serial images for the arterial phase and medulla phase. Spectral characteristic parameters and spectrum curve between different grades of renal cell carcinoma was compared, and the results were compared with pathology. Results Among the 40 cases of patients, carcinoma of grade I, II and III were 13 cases, 15 cases and 12 cases respectively. CT value ratio of renal clear cell carcinoma of grade I, II and III under 70 keV were 1.17±0.25, 0.84±0.85 and 0.64±0.19 (F=23.697, P<0.05) in arterial phase and 0.83±0.12, 0.64±0.07 and 0.54±0.08 (F=30.975, P<0.05) in medulla phase;iodine concentration ratio was 1.19±0.40, 0.60±0.10 and 0.25±0.94 (F=32.932, P<0.05) in arterial phase, and 0.69±0.18, 0.43±0.94 and 0.26±0.51 (F=28.673, P<0.05) in medulla phase. Spectrum curve slope of renal clear cell carcinoma of grade I, II, III in arterial phase was 4.00±1.24, 2.16±0.95 and 0.92±0.64 (F=23.392, P<0.05), and 3.54±1.20, 2.70±0.71 and 1.20±0.44 (F=24.272, P<0.05) in medulla phase. Differences of water concentration in arterial and medulla phase between renal clear cell carcinoma with different grade were not statistically signiifcant (P>0.05). Conclusion The differences of CT value, energy spectrum curve slope, iodine value under CT spectroscopy single energy imaging between renal clear cell carcinoma with different nuclear grade were statistically signiifcant, which can be expected to provide the basis for preoperative therapy selection.
