Objective To compare the therapeutic effects between cervical and extra-cervical surgical approaches for endoscopic thyroidectomy . Methods From October 2012 to December 2013, forty-four thyroid goiter patients were divided into two groups randomly .Group A underwent modified Miccoli endoscopic thyroidectomy ( n =20 ) and group B underwent endoscopic thyroidectomy via breast areola approach ( n=24 ) .The operative time , intraoperative blood loss , pain in 24 hours postoperatively , drainage volume , postoperative hospital stay , hospital cost , complication and cosmetic results between the two groups were compared . Results Compared with group B, group A had shorter operative time [(77.9 ±28.3) min vs.(97.9 ±30.0) min, t=-2.259, P=0.029], less intraoperative blood loss [(15.9 ±8.7) ml vs.(29.5 ±16.1) ml, t=-3.384, P=0.002], less pain in 24 hours postoperatively ( no pain, endurable pain , intolerable pain in group A and B were 15, 5, 0 and 7, 15, 2 cases respectively , Z=-3.066, P=0.002), less postoperative drainage volume [(31.7 ±10.3) ml vs.(57.0 ±14.6) ml, t=-6.511, P=0.000], but poorer cosmetic results (very dissatisfied, not satisfied, satisfied, comparatively satisfied, and very satisfied in group A and B were 1, 4, 5, 6, 4 and 0, 1, 4, 5, 14 cases respectively, Z=-2.723, P=0.006).There was no significant difference in postoperative hospital stay and hospital cost between the two groups (P>0.05).One case suffered transient hoarseness in group A and one case had trembling hand due to low calcium level in group B and both of them recovered 1 month after symptomatic treatment .No permanent recurrent laryngeal nerve injury , parathyroid injury or other complications occurred in both groups . Conclusions Cervical approach is minimally invasive and leads to good cosmetic results while extra-cervical approach causes bigger trauma but leads to better cosmetic results.Patients with high cosmetic reguest may choose endoscopic thyroidectomy via breast areola approach .

Objective To observe the clinical efficacy of lung detoxification soup for treatment of patients with ventilator associated pneumonia(VAP)and its effects on serum procalcitonin(PCT),high sensitivity C reactive protein (hs-CRP)and white blood cell count(WBC). Methods A prospective randomized controlled trial was conducted, sixty cases of VAP with traditional Chinese medicine(TCM)syndrome of accumulation of phlegm and heat in lung from Department of Intensive Care Unit(ICU)in the First Affiliated Hospital of Anhui TCM University were enrolled, and the CASIO fx-360P function calculator was applied to generate random numbers to proceed to simple randomized dividing into two groups(each,30 cases). In the control group,mechanical ventilation,anti-infection,prevention of stress ulcer,early enteral nutrition,early weaning of ventilator and conventional western medicine treatment were given to the patients,while in the treatment group,based on the above conventional treatments in the control group,additionally the lung detoxification soup was given(soup composition:radix astragali 20 g ,baical skullcap root 15 g,coptis 10 g,shellfish 8 g,pinelliae tuber 10 g,white mustard seed 10 g,heartleaf houttuynia herb 15 g, honeysuckle flower 15 g,forsythia 15 g,banlangen 15 g,rhubarb 10 g,salvia miltiorrhiza 30 g)by nasal feeding, once 100 mL,twice a day. The therapeutic course was 7 days in both groups. The changes of TCM syndrome integral, levels of serum PCT,hs-CRP and WBC before and after treatment and the clinical efficacy were compared between the two groups. Results After treatment,the TCM syndrome integral,the levels of WBC,serum PCT,hs-CRP were significantly lower than those before treatment in both groups,and the decrease in treatment group being more marked〔TCM syndrome integral:4.73±1.10 vs. 10.33±1.46,WBC(×109/L):8.71±0.55 vs. 10.77±0.65,PCT (μg/L):1.64±0.40 vs. 5.71±1.25,hs-CRP(mg/L):4.96±1.06 vs. 8.85±1.53,all P<0.05〕. The total effective rate of treatment group was significantly higher than that in the control group〔(93.33%(28/30)vs. 73.33(22/30),P<0.05〕. Conclusion The lung detoxification soup can significantly improve the clinical symptoms,reduce the levels of WBC,serum PCT and hs-CRP in patients of VAP with TCM syndrome of accumulation of phlegm and heat in lung, therefore the soup may play a beneficial role as an adjuvant therapy for such patients.
