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 evaluate the influence of self-etch adhesive,total-etch adhesive and glass ionomer cement on the marginal microleakage of class II restorations. Methods Thirty human premolars were randomly divided into 3 groups(n=10),and cuboid class II cavities(4.0 mm?3.5 mm?2.5 mm) were prepared.Restoration was performed using self-etch adhesive+nano-resin(self-etch group),total-etch adhesive + nano-resin(total-etch group) or glass ionomer cement(glass ionomer group).Half of each group underwent 200 thermocyclings and the other half underwent 500 thermocyclings.The specimens were immersed in 0.5% basic fuchsin for staining.Each tooth was then evaluated the microleakage at the axial wall and the gingival wall section by section under a stereomicroscope.The data were statistically analyzed. ResultsSelf-etch group had significantly more miroleakage than total-etch group and glass ionomer group after 200 and 500 thermocyclings(P

Neurogranin, a neuron-specific postsynaptic protein, has been considered to play an important role in synaptic plasticity and learning and memory. The present study aimed to investigate the effects of prenatal restraint stress on neurogranin expression in rat offspring hippocampus. Pregnant rats were given a restraint stress (3 times a day for 7 d, 45 min each time) at the late stage of gestation except that in the control group. The offspring rats were divided into four groups: female control group, male control group, female stress group and male stress group. Expression of neurogranin was determined by immunohistochemistry and Western blot. The results showed that neurogranin-positive immunostaining was detected in all areas of the hippocampus. The staining density was stronger in the CA1 and CA3 regions than that in the dentate gyrus (DG) region. Western blot assay showed that neurogranin protein level in female and male prenatal stressed offspring was significantly lower than that in the controls (P<0.01). Neurogranin level was significantly lower in the female stress group than that in the male stress group, whereas there was no significant gender difference in the control group. Immunohistochemical data further confirmed these results. The present study provides evidence that prenatal restraint stress induces gender-dependent decrease in neurogranin expression in the offspring hippocampus. The prenatal restraint stress-induced decrease in neurogranin expression in the hippocampus might be associated with the deficit in spatial learning and memory reported previously.

Objective To investigate the independent factors influencing the efficacy of pre-hospital CPR effect. Method The data base with 1376 cases was set up with EpiData software by means of questionnaires and the information was provided by the survivals from cardiopulmonary arrest( CA)saved with cardiopulmonary resuscitation(CPR), and the data were analyzed with SPSS 13.0 software to carry out binary logistic regression. Through single factor analysis, the factors with emerged statistical significance were chosen as variances. Results With regard to the restoration of spontaneous circulation(ROSC), the rescue did by the first witness was the protective factor(PF)( OR = 2.21, P = 0.001, 95.0% CI=1.356-3.602); the male was the risk factor(RF) contrasted with the female( OR = 0. 515, P =0. 006, 95.0%0 CI = 0.320 - 0. 26) ; ages between 20 and 29 years old had higher likelihood of ROSC than group ≥81 years old( OR = 3.241, P = 0.026, 95.0%CI = 1.146 -9.138); the length of CA time before CPR was RF(OR = 0.913, P = 0.000, 95.0%CI = 0.887-0.948);ventricular fibrillation(VF) was PF compared with asystole( OR = 5.092, P = 0.000, 95.0%CI=2.927 -8.861); electric shock was PF(OR = 3.384, P = 0.000, 95.0%CI = 2.033 - 5.635); epinephrine dosage 0 - 4 mg had higher likelihood of ROSC than > 5 nag dosage( OR = 3. 255, P = 0. 001, 95.0% CI = 1. 606 -6.597). In respect of probability about victims at the tittle reached hospital alive, ages of 2- 12 and 13 - 19 years old had higher rations than ≥81 years old( OR = 12.818, P = 0.029, 95.0% CI = 1.299 - 126.508)( OR = 10.505, P = 0.036, 95.0% CI = 1.161-95.058); the length of CA time before CPR was RF(OR =0.862, P = 0.000, 95.0%CI = 0.821-0.906); VF was PF compared with asystole(OR = 7.330, P =0.000, 95.0%CI = 3.962 - 13.560). Conclusions ECG change before CPR, rescue by the first witness,electric shock, the length of CA time before CPR, epinephrine dosage, gender and age were independent influencing factors of pre-hospital CPR for the emergency of ROSC. Age, the length of CA time before CPR and ECG before CPR were influencing factors of pre-hospital CPR for patients at the time transferred to hospital alive.

Objective To understand time-effect relationship in prehospital emergency care of trauma patients so as to cut down mortality. Methods The data of pre-hospital deaths of trauma pa-tients were collected from 67 Shenzhen Emergency Network Hospitals during 2002-2004 and input into a database established by using Foxpro 6.0.Then, the data were analyzed by software SPSS 11.0. Re-sults A total of 161 364 trauma patients received prehospital emergency call service during 2002-2004 and 3 967 patients died prehospital or in hospital.There were 360.528 and 645 trauma patients died pre-hospitsl in 2002, 2003 and 2004 respectively, accounting for 32.57%, 37.69% and 44.25% respec-tively of whole trauma emergency patients in corresponding year.In 2002, 2003 and 2004 respectively, pre-hospital mortality was 1.15%, 0.88% and 0.99%, ratio of male to female 79.17/20.83, 77.65/22.35 and 71.63/28.37, the death age(29.04 ±13.98), (27.84±18.54)and(29.25±17.06)years old, ratio of traffic trauma to non-traffic trauma 48.33/51.67.26.14/73.86 and 37.98/62.02, the median response time of ambulance in hospital 2, 2 and 1 minute, the median time of ambulance arri-ving at the accident scene 5, 8.5 and 7 minutes and the median time of ambulance to and fro was 15.35 and 30 minutes. Conclusions There is a tendency that the number of the pre-hospital deaths of trauma patients increases, but that the ratio of traffic to non-traffic trauma and mortality decrease.The average age of dead trsuma patients is 10 years younger than that of whole emergency patients in the city of Shenz-hen.The response time of ambulance in hospital shortens, but the time of ambulance arriving accident 8cene and to and fro time of ambulance prolong.
