OBJECTIVETo analyze the perioperative complications of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture.

METHODSFrom June 2009 to December 2011, 63 patients with osteoporotic vertebral compression fracture underwent PKP, there were 18 males and 45 females with an average age of 75.3 years ( ranged, 62 to 91). All patients with severe back pain and without neurological symptoms and signs, which were confirmed by X-ray and MRI. Among them,there were 63 cases with severe osteoporosis, 37 cases with hypertension, 10 with coronary artery disease, 29 with anemia, 26 with diabetes, 11 with chronic obstructive pulmonary diseases and 8 with gastritis and peptic ulcer. The common perioperative complications were retropectively reviewed.

RESULTSPreoperative complications occured in 9 cases (14.3%), including hypostatic pneumonia (1 case), electrolyte disturbances (2 cases), urinary tract infection (2 cases), moderate anemia(2 cases),electrolyte disturbances combined with moderate anemia (1 case), hypostatic pneumonia combined with delirium (1 case). Intraoperative and postoperative. complications occurred in 17 cases (26.9%), there were bone cement correlated complications in 9 cases (14.3%), in which 2 cases of toxic reaction of bone cement and 7 cases of leakage (2 cases had clinical symptoms); there were non-bone cement correlated complications in 3 cases (4.8%), in which 1 case of focal hematoma caused by paracentesis, 1 case of transient nerve injury, 1 case of left intercostal neuralgia;there were transient hyperpathia in 5 cases after operation. All complications result in no severe consequence after treatment.

CONCLUSIONPerioperative complications of percutaneous kyphoplasty are not uncommon,however,these complications may not cause serious consequence after active treatment,so prevention and treatment are important for it.

The conservation of long noncoding RNA (LncRNA), including primary structure, spatial structure, transcriptional position, splicing mode and tissue distribution, is research focus of LncRNA research. In-depth studies of lncRNA conservation can be applied to the screening process of lncRNA in non-modal organisms, which lack adequate reference genome databases, greatly enhancing the integrity and accuracy of lncRNA databases of non-modal organisms. LncRNA screening tools or processes such as CPC and pipeline for lncRNA annotation from RNA-seq data (PLAR), which have been developed by length of open reading frame, distribution and frequency of codon, functional domain and other conservative information, are new strategies for the screening of lncRNA and construction of reference database of non-model organisms. In this review, we summarized the conservation of lncRNA and its application in screening lncRNA in non-model organisms, and briefly introduced PLAR, anew screening method using the conservation of lncRNA.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

Objective To detect the mutations of ATP2C1 gene in patients with Hailey-Hailey dis- ease (HHD).Methods PCR and direct sequencing were performed in 17 patients and 120 healthy controls to screen the mutations in the exons of ATP2C1 gene.Results Eight mutations were identified in nine probands, including three deletion mutations (nt1464-1487 del/nt1462-1485del,1523delAT,2375delTTGT),three splice site mutations (360—2A→G,1415—2A→T,2243+2T→C) and two missence mutations (C920T and G1942T).None of the above mutations was found in the controls.Conclusion Eight specific novel mutations were identified in nine probands of HHD,which could be causative factors of the disease.

Objective To study the vascular compression on the ponline cistern of the trigeminal with magnetic resonance diffusion tensor imaging (DTI) and explore the clinical application value of DTI.Methods Sixty patients who were conformed by operation as having trigeminal neuralgia (TN) caused by responsible vascular compression (TN group) and 50 healthy volunteers (control group) were performed conventional MRI and horizontal DTI to measure the apparent diffusion coefficient (ADC)value and fractional anisotropy (FA) value. Results The ADC value and FA value of trigeminal nerve in control group were (1.76±0.98)×10-3 mm2/s, and (0.40±18), respectively, no significant differences of the ADC value and FA value between the left and right trigeminal nerves were found (P>0.05). The ADC and FA values of the trigeminal nerve among the controls, patients with mild or severe compression and the patients with compression combined with neuratrophia were statistically difrerent(P<0.05). The ADC value in the oppression region was increased in 28 patients and unchanged in 4; the average ADC value in the NT group was significantly higher than that in the control group. FA value in the oppression region decreased in 15 patients, unchanged in11 and increased in 5; the average FA value in the NT group was lower than that in the control group. Conclusion DTI has its value in determining the vascular compression of the trigeminal nerve; the greater the degree of trigeminal nerve compression is, the higher the ADC value and the lower the FA value are.

OBJECTIVETo investigate the factors of long-turn survival of liver cancer after surgical treatment.

METHODSFive hundred and twenty-two cases of liver cancer that received surgical treatment in 14 years were analyzed retrospectively.

RESULTSComparison between the small liver cancer (< 5 cm) and the greater one (> 10 cm) revealed that the small liver cancer had a higher survival rates than the greater one [3 year (61.25 +/- 4.41)% versus (45.90 +/- 6.98)%; 5 year (53.84 +/- 5.68)% versus (30.21 +/- 10.23)%]. There were same results between single-nodule and two or more than two nodule [3 year (61.86 +/- 3.69)% versus (38.31 +/- 4.97)%; 5 year (55.40 +/- 4.91)% versus (28.01 +/- 6.31)%], between child I and child II or more than II [3 year (60.68 +/- 3.68)% versus (49.88 +/- 4.13)%; 5 year (50.99 +/- 5.10)% versus (36.39 +/- 7.58)%], and between single segmentectomy of the liver and two or more than two segmentectomy [3 year (68.65 +/- 4.95)% versus (49.88 +/- 4.13)%; 5 year (65.38 +/- 5.69)% versus (37.98 +/- 5.70)%].

CONCLUSIONSSmall liver cancer, single-nodule, good hepatic function and minor resection were important factors to prolong survival further.
