OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.

CONCLUSIONMobi-C CADR retains the movement unit in the decompression segment and can quickly recover normal action for patients. Using CADR method has a good curative effect in the early phase, and the clinical effect is reliable, may improve the quality of life.

Objective To investigate the clinical characteristics and chronological change of ulcerative colitis(UC) in the Chinese PLA General Hospital in near 16 years. Methods Patients diagnosed with UC during the period from 1994 to 2009 in the Chinese PLA General Hospital were registered and their clinical profiles were analyzed. Results From 1994 to 2009, of 525 patients diagnosed with UC, with a median onset age of 42 years. The predominant form of UC was extensive colitis, which affected almost 33.3% (175/525), left-sided colitis was present in 21.3% (112/525) and rectum was present in 12.4%(65/525). The chronic relapsing type of UC was the most common (69.0%, 362/525 ), followed by the initial onset type (18. 1%, 95/525 ), chronic continuous type with intermittent exacerbations (9.7%,51/525), and acute fulminant type (3. 2%, 17/525 ). Two hundred and twenty-one patients (42. 1%,221/525) were graded as mild, 162 (30.9% , 162/525) as moderate, and 142(27.0%, 142/525) as severe UC. The proportion of mild colitis and rectum was significantly higher in patients with an onset age of over 60 years, compared with those with an onset age of less than 30 years( P ＜0. 05 ). The proportion of UC patients with old age onset ( P ＜ 0. 05 ), male sex ( P ＜ 0. 01 ), mild colitis ( P ＜ 0. 01 ), rectum ( P ＜0. 01 ) , relapse-free type ( P ＜ 0. 01 ) demonstrated a chronological increase from 1994 to 2009.Conclusions The distinctive clinical features and chronological change were seen in UC patients in recent years. Compare to those with an onset at less than 30 years, the proportion of mild colitis and rectum was significantly larger in patients with an onset at over 60 years of age, and the proportion of UC patients with old age onset, male sex, mild colitis, rectum, relapse type were less.

The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.

Objective To investigate the role of synapsin-I in the differentiation of the embryonic stem cells (ESC) into the neuron,and to seek a controllable point for the ESC neural differentiation in vitro.Methods Neural differentiation of ESC was induced with the "five step approach",synapsin-I antisense oligonucleotides (AS ONs) was employed to inhibit the synapsin-I expression at different stages. At different time points,morphology,differentiation efficiency and neural specific markers were compared among the normal group and the transfected groups.A tumor cell line called PC12 cell was compared with the ESC at the same time.Results After the synapsin-I AS ONs were used in ESC differentiation, considerable decreases of neurite growth rate and neural precursor cells (nestin (+)) percentage were observed at Stage 3(68.5%?4.2% vs 76.2%?5.1% and 75.8%?4.9%,P

According to morphological and microscopic characteristics, a high-efficient decolorizing fungus, the strain Asaw117, was identified as Aspergillus awamori. Selecting eight different dyes from Azo dyes, anthraquinones dyes and oxygen Quinones dyes, the decolorizing assays of various dyes showed that the strain Asaw 117 was the highest decolorizing potential to 0.1 g/L Vat Blue RSN, the discoloration rate up to 100 percent. Comparing to different kinds of medium and several of carbon and nitrogen sources, the strain had the best decolorizing efficient although grew slower in the Czapek medium, otherwise, grew quicker and decolorizing efficient lower in the PDF medium. It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources. So the strain has good potential for the dyeing wastewater treatment

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.
