Objective To investigate influence of different usage of dyclonine hydrochloride mucilage on hemodynamics and postoperative throat pain of laryngeal mask anesthesia patients.Methods Sixty patients in flexible ureteroscopic holmium laser lithotripsy with laryngeal mask anesthesia were randomly divided into three groups according to different usage of dyclonine hydrochloride mucilage (n =20).Group A was coated laryngeal mask with paraffin oil.Group B was coated laryngeal mask with dyclonine hydrochloride mucilage.Group C was coated laryngeal mask with dyclonine hydrochloride mucilage and dyclonine hydrochloride mucilage gargle.The indwelling time of laryngeal mask, postoperative recovery time of spontaneous breathing, time of hearing the call to open eyes, and the time of pulling out the laryngeal mask were recorded.Heart rate (HR), mean blood pressure (MBP) index at T1 (pre-anesthesia induction), T2 (1 min before pulling out the laryngeal mask), T3 (pulling out the laryngeal mask), T4 (5 min after removing the laryngeal mask), and T5 (10 min after removing the laryngeal mask) were recorded.The complications of throat after removing laryngeal mask were observed.The pain degree of sore-throat at the time of 30 minutes after removing the laryngeal mask was observed.The adverse reactions of the usage of dyclonine hydrochloride were observed in three groups.Results There were no statistically significant differences in indwelling time of laryngeal mask, postoperative recovery time of spontaneous breathing, time of hearing the call to open eyes, and the time of pulling out the laryngeal mask among three groups (P ＞ 0.05).There were no statistically significant differences in HR, MBP at T1 , and T5 (P ＞ 0.05).HR and MBP were higher in group A than in groups B and C at T2 ～ T4, and HR and MBP were higher in group B than in group C at T2 ～ T4, with statistically significant difference (P ＜ 0.05).The incidences of sore throat and swallowing discomfort were significantly lower in groups B and C than in group A (P ＜ 0.05).The incidences of sore throat and swallowing discomfort were significantly lower in group C than in group B (P ＜0.05).No statistically significant difference were found in incidence of hoarseness among three groups (P＞ 0.05).The pain degree of sore-throat in group C were significantly lower than in group B, and the pain degree of sore-throat in groups B and C was significantly lower than in group A (P ＜ 0.05).There were no allergic reactions and local anesthetic poisoning for three groups.Conclusions Dyclonine hydrochloride mucilage can reduce hemodynamic fluctuations during recovery period, and prevent or relieve effectively the patient's throat pain after laryngeal mask anesthesia.At the same time, dyclonine hydrochloride mucilage can improve the patient's postoperative physical comfort without adverse reactions, especially coated laryngeal mask with dyclonine hydrochloride mucilage and dyclonine hydrochloride mucilage gargle.

Objective To examine the effect of berberine on tumor necrosis factor-α(TNF-α)-induced VEGF expression and the possible mechanism.Methods There were two sessions in this study.In the first session,HepG2 cells were treated with 10 ng/mL TNF-αfor 0,12,24 and 48 h,respectively.In the second session,HepG2 cells were pre-incubated with 0,10,25 and 50μmol/L berberine for 24 h,respectively,and then treated with 10 ng/mL TNF-αfor 24 h.The effect of berberine on the prolif-eration of HepG2 cells was assayed by MTT.The level of VEGF mRNA was detected by real-time PCR,and the expression lev-els of VEGF,IκBαand NF-κB p65 proteins by Western blot.The activity of NF-κB was measured by ELISA.Results Berberine could dose-dependently inhibit the growth of HepG2 cells.TNF-αcould increase the mRNA and protein expression levels of VEGF in HepG2 cells in a time-dependent manner.Berberine could significantly dose-dependently down-regulate the TNF-α-in-duced VEGF expression at mRNA and protein levels.TNF-αsignificantly decreased the expression of IκBαand increased the ex-pression of NF-κB p65 and the activity of NF-κB in a time-dependent manner,which could be dose-dependently abrogated by pretreatment with berberine.Conclusion Berberine inhibits TNF-α-induced VEGF expression via NF-κB signaling pathway.

Objective To evaluate the feasibility and safety of endoscopic thyroidectomy via anterior chest and breast for the treatment of patients with papillary thyroid carcinoma ( PTC ).Methods Endoscopic thyroidectomy was performed in 85 PTC patients between March 2006 and March 2010. Diagnosis was based on intraoprative frozen section. There were 83 females and 2 males, age averaged at 36. 3 years. Sixty three of 85 cases were diagnosed preoperatively as thyroid carcinoma and US revealed ipsilateral cervical lymph node enlargement suspective of metastasis in 12 cases. Endoscopic thyroidectomy plus selective neck dissection was performed. Results This procedure was carried out successfully in 84patients. There were 51 cases of papillary thyroid microcarcinomas(<1. 0 cm) , 28 cases between 1. 0 cm and<2. 0 cm, and 5 cases with the diameter between 2. 0 cm and 3. 0 cm. Total thyroidectomy, ispilateral lebectomy and ispilateral lebectomy plus contralateral subtotal lobetomy were performed in 4, 6, 74 cases,respectively. Central compartment dissection was performed in all of the 84 cases and ipsilateral neck dissection was also performed in 12 cases that were suspected metastatic lateral neck lymph nodes. The mean operative time was (113. 3 ±46. 5) minutes. No significant blood loss occurred. The mean number of lymph nodes yield in the central compartment and lateral compartment were 6. 5 (range 2 to 14) and 19. 2 (range 9 to 26 ), respectively. Forty-four cases ( 44/84, 52. 4% ) had metastatic lymph nodes in central compartment, while 11 cases (11/12,91.1% ) in lateral compartment. Six patients (6/84,7.14%) had transient vocal cord palsy and recovered after 1-2 months. Postoperative transient hypocalcaemia occurred in 4 cases (4. 8% ) , and there were no other major complications. The average postoperative hospital stay was 3. 7 days (range 3 to 6). No evidence of residual or recurrent disease was found at follow-up. The cosmetic results of this procedure were excellent. Conclusions The anterior chest and breast approach of endoscopic thyroidectomy is feasible and safe and cosmetic worthwhile for selected cases of PTC.

Objective To report a randomized trial in comparing the clinical outcomes of three-port LC versus standard four-port LC. Methods From March 2001 to August 2004, four hundred consecutive patients who underwent elective LC were randomized to receive either the three-port or the four-port technique. All patients were blinded to the type of operation they underwent. Postoperative overall pain and incisional pain at different sites were assessed on the first day after surgery using the Prince-Henry scale. Other outcome measures included length and success of the operation, analgesia requirements, postoperative complications, postoperative stay, and the cosmetic results. Results There was no difference between the two groups in age, sex, weight or other diseases. In terms of outcome, patients in the three-port group had less pain at individual subcostal port sites and better cosmetic results. Success rate, mean operative time, complications, subxiphoid port and overall pain score, analgesia requirements, and postoperative hospital stay were similar between these two groups. Conclusion Three-port LC resulted in less individual port-site pain and similar clinical outcomes but fewer surgical scars compared to four-port LC. The three-port technique is as safe as the standard four-port procedure for LC. Thus, it can be recommended as a routine procedure in elective LC.

Objective To study the frequency of cystic fibrosis transmembrane conductance regulator(CFTR)mutations in patients with congenital bilateral absence of vas deferens(CBAVD).Methods Eighty-five CBAVD patients were collected from May 2007 to May 2009.The diagnosis of CBAVD included azoospermia,normal of 4 sex hormone items,absence of seminal vesicle,normal volume of testicular and epididymis dilated siltation.And 85 normal fertile men served as controls.Genomic DNA was isolated from peripheral blood.The mutations of CFTR exons 10,11 were detected by PCR-single strand conformation polymorphism,and direct sequencing was performed on 85 cases of CBAVD and the control males.Results Of the 85 CBAVD,10 cases(11.8％)exhibited an abnormal CFTR gene mutation,with 4 cases I556V,2 cases M469V,and 1 case of E527N,A F508,L558S,S485C.No mutations were detected in 85 controls.There was a significant difference between the 2 groups(x2 =8.606,P =0.003).Conclusions CBAVD might be caused by the CFTR mutations.The frequencies and the spectrum of CFTR mutations might be different from those Caucasian population in the west country.
