OBJECTIVEThe aim of this retrospective study is to present the long-term effects of open healing of keratocystic odontogenic tumors (KCOTs) in the mandible.

METHODSA retrospective case series study was conducted on 41 patients with large KCOTs (the maximum diameter of the tumors exceeded 5 cm) treated at our institution between September 2003 and April 2011. A conservative surgical treatment was applied. The treatment involved enucleation of the primary lesion through narrow unroofing and open packing of the residual osseous defect with iodoform gauze for secondary healing. Bone regenera- tion and surgical complications were observed. The long-term effects of the treatment were followed up.

RESULTSThe inferior alveolar nerve was exposed in the KCOT bone cavity in all cases, and some nerves adhered to the tumor tightly. The post- operative follow-up time was 81.5 months on the average (36 to 127 months). The packing gauze was changed every two weeks after enucleation, and the total duration time for packing was 8.9 months on the average (3 to 15 months). Notable bone regeneration and satisfactory secondary healing were observed clinically and radiographically. The KCOT-affected teeth were reserved, and their chewing functions were restored. Two cases presented recurrences after the initial treatment. The recurrence rate was 4.9% (2/41). No serious complications were observed.

CONCLUSIONEnucleation associated with subsequent open packing is a reliable treatment for patients with large KCOTs in the mandible.

Objective:To study the efficacy and safety of natural calcined bone repair material(NCBM)in repairing bone defect af-ter tooth extraction.Methods:A randemized,double-blinded,parallel,positive control(Bio-Oss)and multi-center clinical trial was employed.Imaging examination was used as the main efficacy evaluation index,surgical wound healing,rejection reaction,bone me-tabolic changes,bone infection signs were the subordinate efficacy evaluation indexes,the incidence of adverse reactions was observed for safety evaluation.Results:280 cases were included,269 cases completed the trial.In NCBMand Bio-Oss group the effective rate of imaging examination was 93.08% and 93.70%(P >0.05)respectively.The wound healing time of the 2 groups was less than 7 days,no rejection reaction,bone metabolic change and bone infection sign were observed.The incidence of adverse events in NCBM and the Bio-Oss group was 0.72% and 2.14%(P >0.05)respectively.Conclusion:The efficacy and safety between natural cal-cined bone repair material is not inferior to Bio-Oss in repairing bone defect after tooth extraction.

Objective:To compare the outcomes of guide bone regeneration by calcined bovine bone and Bio-Oss graft material in alveolar ridge preservation after tooth extraction.Methods:280 patients were divided into two groups randomly.Each patient had single tooth extracted.The sockets were filled with calcined bovine bone in 140 patients and Bio-Oss graft in another 140 patients. After shaping,all the sockets were covered with Bio-Gide membrane.Buccal mucoperiosteal flap was released and sutured to close the alveolar sockets.The patients were regularly examined at the 1st,12th and 24th week after surgery.Physical examination and X-ray evaluation were applied to compare the outcomes of the two materials in alveolar ridge preservation.Results:No infection and re-jection occurred.The radiographic results showed the width and height of the alveolar bone were preserved well at the 12th and 24th weeks.No statistically difference was found in the two groups at the 1st and 24th weeks(P>0.05).Conclusion:The two graft ma-terials can effectively preserve alveolar bone after tooth extraction.

Objective To Pulse oximetry saturation has been wildly used clinically.It has been reported that pulse oximetry plethysmographic waveform (POP) reflected the peripheral tissue perfusion.In this study,we parameterized POP,observed the value of POP parameters in normal adults,and established the normal reference value range.Methods A multi-center prospective descriptive study.Total of 1 019 adult volunteers with normovolemia from 7 cities were enrolled in this study.Sex,age,height,weight and pulse oximetry data in awake and spontaneous breathing under in quiet conditions in the room temperature were collected.POP parameters and perfusion index were analyzed using MATLAB 2012a software.The normal reference value ranges of POP parameters,including the amplitude of POP (Amp) and the area under the curve of POP (AUC),were formulated.Results Statistical differences of POP parameters were detected between men and women in the normal adult.The 95％ confidence reference value of POP parameters in normal population was as follows:Amp (104.8-2298.7) PVA and AUC (3265.8-6028.5) PVPGin total,Amp (129.4-2433.6) PVA and AUC (3319.0-5862.2) PVPG in male;Amp (89.5-2138.2) PVA and AUC (3163.9-5929.9) PVPG in female.Conclusions POP,including the amplitude of POP (Amp) and the area under the curve of POP (AUC),had normal reference value ranges in normal adults.

Objective:To observe the results of electroacupuncture (EA) on the resuscitation of a rat model of asphyxia cardiac arrest (CA). And to explore its effect on the neurologic deficits and hemodynamic instability of post-cardiac arrest syndrome (PCAS).Methods:A total of 107 male SD rats were randomly divided into sham, CA, and EA groups. Each group received arterial catheterization and tracheal intubation. The sham group was not induced asphyxia. Asphyxial cardiac arrest was established by endotracheal tube clamping. Rats in the CA group received basic respiratory support and fluid resuscitation in return of spontaneous circulation (ROSC) and rats in the EA group received EA at Baihui based on the treatment of CA group after ROSC, with a dense-dispersed wave at frequencies of 4-20 Hz, while the current intensity was adjusted minimum to induce a twitch of the scalp, the course of treatment was 30 minutes. The baseline data, hemodynamics after ROSC, neurological deficit score (NDS), pathological changes of brain tissue, and levels of serum biomarker were recorded and compared among the three groups. The 72-hour survival of rats was analyzed by Kaplan-Meier survival curve. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of necrotic neurons in the hippocampal CA1 region of rat brain. Meanwhile, Nissl staining and TdT-mediated dUTP nick-end labeling (TUNEL) were used to detect cell apoptosis and injury.Results:Compared with the CA group, the mean arterial pressure (MAP) in the EA group increased significantly at 15 minutes after ROSC [mmHg (1 mmHg≈0.133 kPa): 125.00 (94.00, 136.25) vs. 92.00 (72.00, 122.50), P < 0.05]. There was no significant difference in the NDS score between the EA group and the sham group. Still, the NDS score of the rats in the CA group at 6 hours after ROSC were significantly lower than that in the sham group (46.00±10.61 vs. 80.00±0.00, P < 0.05). Kaplan-Meier survival curve analysis showed that EA did not improve the 72-hour survival rate of rats (100% in the sham group, 25% in the CA group, and 30% in the EA group, P > 0.05). The analysis by TUNEL showed that the apoptosis rate of neurons in CA1 region of the hippocampus in EA group at 6 hours after ROSC was significantly lower than that in CA group [(62.84±2.67)% vs. (71.29±3.70)%, P < 0.05]. Compared with the CA group, the level of serum S100 calcium binding protein B (S100B) in the EA group at 6 hours after ROSC was significantly lower (ng/L: 19.30±13.87 vs. 132.28±31.67, P < 0.05), but there were no significant differences in the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) between these two groups. Conclusions:In the present study, EA at Baihui can stabilize the hemodynamic, moreover, it has a particular neuroprotective effect on PCAS rats. Still, EA at Baihui does not reduce the systemic inflammatory response and improve the survival rate of rats, and its mechanism remains to be verified in further research.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
