OBJECTIVE: The aim of the present study was to evaluate the effects of radiofrequency coblation surgery for treatment of abnormal sensation of throat induced by the hypertrophy of lingual tonsil. METHOD: Three hundred and seven patients affected by abnormal sensation of throat induced by the hypertrophy of lingual tonsil were enrolled. Radiofrequency coblation was performed on all patients under nasal endoscopy. A comprehensive statistics were obtained from all the participants regarding the recovery of wound surface, postoperative pain, intra and postoperative bleeding and the effects of the procedure. RESULT: The VAS score of abnormal sensation of throat was reduced from (9.3 +/- 0.6) to (3.7 +/- 2.4) (P<0.05) after the operation. 84.4% of the abnormal sensation dis appeared, no recurrence within six month; 6.8% of the abnormal sensation largely reduced within six month; 4.6% of the abnormal sensation reduced within six month. There was no significant postoperative pain. 3.6% (11/307) of patients experienced postoperative hemorrhage. The follow-up period ranged from 6 to 36 months, there was no recurrence. CONCLUSION Radiofrequency coblation is a useful surgical technique, as effective as,or even superior to,other surgical techniques when dealing with patients suffering from abnormal sensation of throat induced by the hypertrophy of lingual tonsil with potentially fewer adverse effects and subsequently improved quality of life for patients.

OBJECTIVETo find an effective operative procedure against reflux after esophagogastric anastomosis with mucosal valve.

METHODSFour hundred and sixty-four patients with esophageal or cardiac cancer were randomly divided into three groups according to anastomosis modes. Group A underwent esophagogastric anastomosis with mucosal valve (175 cases), group B with mechanical stapler (151 cases) and group C one layer anastomosis with handcraft suture (138 cases). The gastroesophageal reflux index (GERI) was examined by isotope,and 24 h esophageal pH was also monitored. The esophageal motor function was compared among three groups.

RESULTSThe reflux rates were 0, 33.3%, and 6.7% in group A, B, C respectively. The esophageal motor function and the 24 h esophageal pH monitoring indicated that the various indexes were approaching to the normal level in group A, but the various indexes in group B and C were significantly different from the normal values (P< 0.05).

CONCLUSIONThe esophagogastric anastomosis with mucosal valve has better antireflux effect and can prevent the reflux esophagitis after esophageal or cardiac cancer eradication.

Objective:To investigate the psychological depression of obese patients with acanthosis nigricans (AN), in order to provide evidence for clinical treatment.Methods:From March 2014 to August 2014,a total of 88 consecutive patients with obese were treated in our department,56 age-matched normal weight healthy volunteers were included as control group.They were divided into simple obesity group (OB,n= 30)and obesity with acanthosis nigricans group (AN,n= 58). The self-administrated Beck Depression Inventory-Ⅱ questionnaire was used in three groups,and general characteristics and clinical data were collected for analysis.Results:Compared with OB group,AN group had higher levels of FFA and UA (P<0.05).The severity of depression was significantly higher in AN group than OB group and the control group (P<0.05).The frequency of depression was recorded as 67.2% in the AN group,43.4% in OB group,and 3.6% in control group (P<0.05).Conclusions:Obese patients with AN has severer metabolism disorder and severity of depression than simple obesity patients.Psychotherapy is necessary for AN patients when treat for obesity .

OBJECTIVETo explore the relationship between body mass index, waist circumference and blood pressure among residents in Chongqing area.

METHODSA total of 5246 residents aged 15 and over in Chongqing area were enrolled in this study by use of stratified sampling and cluster sampling methods. Data on blood pressure (SBP, DBP), pulse, height, body weight, waist and hip circumferences as well as questionnaire survey were analyzed.

RESULTSThe level of SBP and DBP and hypertension prevalence rate were significantly positively correlated with BMI (all P < 0.01). SBP, DBP levels and hypertension prevalence rate were significantly higher in people with abdomen obesity than people with normal waist circumference (all P < 0.01). BMI, waist circumference in hypertensive residents were significantly higher than non-hypertensive residents (all P < 0.01).

CONCLUSIONBlood pressure level and hypertension prevalence rate were closely related with BMI and waist circumference among residents in Chongqing area.

OBJECTIVEThis study was designed to compare clinical efficacy of segmental pulmonary vein ablation (SPVI), amiodarone or amiodarone plus losartan on sinus rhythm maintenance in patients with lone paroxysmal atrial fibrillation (PAF).

METHODSPatients with lone PAF were treated with amiodarone alone (A, n = 52), segmental pulmonary vein isolation (SPVI, n = 51), or amiodarone plus losartan (AL, n = 51). The primary endpoint of this study was the incidence of symptomatic atrial tachyarrhythmia (> 30 s) documented by 12 lead ECG or Holter during 12 months follow-up period.

RESULTSDuring follow-up, AF was documented in 24 patients (46.2%) in A group, 11 patients (21.6%) in SPVI group and 12 (23.5%) in AL group (P < 0.05 vs. A group). The Kaplan-Meier survival analysis demonstrated a significant equally reduction in AF recurrence in SPVI and AL groups (P = 0.009, log-rank test and P = 0.018, log-rank test, respectively) compared with A group. The hazard ratio for AF recurrence in patients treated with SPVI and amiodarone plus losartan was 0.41 (95% CI 0.200 to 0.848, P = 0.016) and 0.46 (95% CI 0.225 to 0.953, P = 0.036), respectively. Incidences of major adverse cardiac events were similar among the groups (9.6% in A, 3.9% in SPVI and 7.8% in AL group, P > 0.05).

CONCLUSIONThe results of this study suggest that the segmental pulmonary vein isolation and amiodarone plus losartan are superior to amiodarone alone for preventing AF recurrence in patients with lone PAF.

Referring to the rules for agricultural seed testing (GB/T 3543-1995) issued by China, the test of sampling, purity, thousand seed weight, moisture, viability, relative conductivity and germination rate had been studied for seed quality test methods of Lonicera macranthoides. The seed quality from 38 different collection areas was measured to establish quality classification standard by K-means clustering. The results showed that at least 7.5 g seeds should be sampled, and passed 20-mesh sieve for purity analysis.The 500-seed method used to measure thousand seed weight. The moisture was determined by crushed seeds dried in high temperature (130±2) ℃ for 3 h.The viability determined by 25 ℃ 0.1% TTC stained 5h in dark. 1.0 g seeds soaked in 50 ml ultra pure water in 25 ℃ for 12 hours to determine the relative conductivity. The seed by 4 ℃stratification for 80 days were cultured on paper at 15 ℃. Quality of the seeds from different areas was divided into three grades. The primary seed quality classification standard was established.The I grade and II grade were recommend use in production.

In order to improve reproductive efficiency and quality standard, the influence factors of seed germination and seeding growth of Lonicera macranthoides werew studied. The fruit and seed morphological characteristics of L. macranthoides were observed, the seed water absorbing capacity was determined, and different wet sand stratification time, temperature and germination bed treatment were set up. The effects of the parameters on seed germination and seedling growth were analysed. There was no obstacles of water absorption on L. macranthoides seed, quantity for 22 h water absorption was close to saturation. In the first 80 d, with the increase of the stratification time, seed initial germination time was shortened, germination rate and germination potential was improved. Stratification for 100 d, germination rate decreased. At 15 ℃, seed germination and seedling growth indicators were the best. The seedling cotyledon width in light was significantly higher than that in dark. Seeds on the top of paper and top of sand germination rate, germination potential, and germination index was significantly higher than that of other germination bed and mildew rate is low. The optimal conditions of seeds germination test was stratified in 4 ℃ wet sand for 80 d, 15 ℃ illuminate culture on the top of paper or top of sand. The first seeding counting time was the 4th day after beginning the test, the final time was the 23th day. The germination potential statistical time was the 13th day after beginning the test.
