Objective To investigate the feasibility,technique and clinical significance of preserving the great auricular nerve in parotid benign tumors surgery during the first postoperative year.Methods Fifty-two patients with parotid benign tumors were randomly divded into 2 groups.24 patients (group sacrificed) underwent classic parotidectomy with sacrifice of the great auricular nerve.The surgeons spare the nerve in the 32 patients with FOCUS ultrasonic harmonic scalpel (group preserved).Results After surgery,both groups showed lower levels of subjective sensation and sensory function test at auricle.These alterations were less pronounced in group preserved.Both groups showed improvement over time.In group preserved the sensory function reached normal level by 12 months after surgery.The recuperation in group sacrificed was partial at 12 months after operation.Conclusion The great auricular nerve preservation during parotidectomy is feasible,It can decrease sensory disturbance in the early postoperative period and avoid the permanent sequelae that occur when the nerve is sacrificed.The FOCUS ultrasonic harmonic scalpel technique can reduce the operation time.

Papillary thyroid cancer (PTC) is the most common type in thyroid carcinomas.Recently,the prevalence and diagnostic rate of PTC has got significantly high with the general use of ultrasound.Nowadays,more and more studies have suggested that the coexistence of PTC and diabetes is common.They indicated that hyperglycemia would induce the deterioration of oxidative stress injury,chronic inflammation,insulin resistance,obesity,dyslipidemia,deficiency of vitamin D and dysimmunity.All of these may break the balance of oxidation and antioxidation and result in disordering signal pathway,accumulation of inflammatory cytokines,over activating of insulin and insulin-like growth factor-1,changing the metabolic pathways,which will promote the occurrence and progression of PTC.

Objective To investigate the changes in proliferation index (PrI) of gingival fibroblasts in nifedipine-induced gingival hyperplasia ( NIFr-HGF). Methods Gingival fibroblasts were derived from a patient with nifedipine-induced gingival hyperplasia. Cells were induced by 10 ng/mL and 1 000 ng/mL nifedipine ( low- and high-concentration drug intervention groups), respectively. Cells were harvested 18 h and 30 h after intervention, cell cycles were detected by flow cytometry, and Prls were calculated. NIFr-HGF without nifedipine induction were served as blank control. Results After induction for the same time, Prls of NIFr-HGF cell cycle of low- and high-concentration drug intervention groups were significantly higher than those of blank control group (P <0.05) , while there was no significant difference between low and high-concentration drug intervention groups (P > 0.05). In low and high-concentration drug intervention groups, Prls of NIFr-HGF cell cycle after intervention for 30 h were significantly higher than those after intervention for 18 h [(57. 54 ± 0.019)% vs (21.15 ±0.011)%, and (59.36 ±0.031)% vs (19.01 ±0.012) %, respectively] (P < 0.05). Conclusion For patients with nifedipine-induced gingival hyperplasia, PrI of NIFr-HGF cell cycle increases with time of nifedipine intervention, while is not significantly related to drug concentration.

Objective To explore the emotional socialization development between boys and girls aged 1-3 years. Methods A total of 1008 children were randomly selected with 571 boys and 437 girls. Chinese version of Urban Infant-Toddler Social and Emotional Assess-ment (CITSEA) was used to assess the emotional socialization development situation between boys and girls. Results There were statistical-ly significant differences between boys and girls in the overt behavior domain and ability domain of CITSEA (t>2.136, P<0.05), and was not in the covert behavior domain and imbalance domain (t<1.172, P>0.05). Conclusion There are gender differences in emotional socialization development of children.

Objective To investigate the effects of endaravane on hypoxia-ischemia (HI)-induced brain injury in neonatal piglets. Methods Male piglets 3-7 days old weighing 2.0-3.0 kg were used in this study. Group Ⅰ 10 piglets were randomly collected as sham operation without HI. Twenty piglets with HI were randomly divided into 2 groups (n = 10 each) : group Ⅱ HI and group Ⅲ HI + endaravone. The animals were anesthetized with intraperitoneal pentobarbital sodium 50 mg/kg, tracheostomized and mechanically ventilated with 30% O_2. Right femoral artery and vein were cannulated. MAP, HR, PET CO_2, blood gases and glucose and rectal temperature were monitored. After 15 min stabilization cardiac arrest was induced by inhalation of hypoxic air (O_2 10%) for 40 min followed by inhalation of 21% O_2 for 5 min. The tracheal tube was then occluded for 7 min. Cardio-pulmonary resuscitation (CPR) was then started until recovery of spontaneous circulation (ROSC). CPR > 3 min was considered a failure. A bolus of endaravone 3 mg/kg was given iv over an hour at 30 min after CPR,followed by continuous infusion at 1.5 mg·kg~(-1)·h~(-1) for 5.5 h in group Ⅲ , while in group Ⅱ vehicle was given instead of endaravone. The neurological function of the animals was evaluated at 48, 72 and 96 h after ROSC and scored (0-154, 0 = normal, 154 = severest dysfunction). The animals were killed at 96 h after ROSC. The brains were removed for microscopic examination of striatum and cortex and determination of 8-hydroxy-2'-deoxyguanine (8-OHdG/OHG) expression in putamen by immuno-histochemistry. Results The neurological function scores were significantly higher at 48 h after ROSC and the number of viable neurons in striatum and sensory cortex were significantly lower and the expression of 8-OHdG/OHG in putamen was significantly higher in group Ⅱ than in group Ⅲ . Conclusion The antioxidant endaravone given after CPR can attenuate Hl-induced brain injury by inhibiting oxidative damage to DNA and RNA.
