OBJECTIVE: To evaluate the efficacy of Yacovino repositioning maneuver in patients with anterior semicircular canal benign paroxysmal positional vertigo (ASC-BPPV). METHOD: Nine patients were diagnosed as ASC-BPPV from January 2013 to October 2014. All the patients were performed with Yacovino repositioning maneuver and the effective rate were evaluated by Dix-Hallpike tests. RESULT: Among the nine ASC-BPPV patients, 2 cases were successfully controlled by the first maneuver, 2 cases by the second time, and the nystagmus of 1 case was disappeared after 1 months' follow-up. The remaining 3 cases were respectively followed up till 7,8, 12 months with consistent positional downbeat nystagmus. CONCLUSION Being a relative low incidence disease, of ASC-BPPV also has low effective rate after Yacovino repositioning maneuver.

Objective To investigate the pathogen distribution and drug resistance of gram-negative bacteria causing lower respiratory tract infections in patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) .Methods A total of 742 sputum samples were collected from AECOPD patients with lower respiratory tract infections in Taizhou Hospital of Zhejiang Province during January 2013 and December 2014.Vitek 2 Compact system combined with disk diffusion was used for strains identification and drug susceptibility test.Modified Hodge test and ethylenediamine tetraacetic acid (EDTA) synergic test were used to screen carbapenem-resistant strains.Statistical analysis was performed using WHONET 5.6 and SPSS 20.0 software.Results A total of 593 strains of gram-negative bacteria were isolated , in which 367 strains were nonfermentative bacteria (61.89%), 220 strains were enterobacteriaceae (37.10%), and the rest 6 strains ( 1.01%) were other gram-negative bacteria.Acinetobacter baumannii ( 186 strains ), Pseudomonas aeruginosa (99 strains), Stenotrophomonas maltophilia (33 strains) and Burkholderia cepacia (22 strains ) were top 4 nonfermentative bacteria , and they all showed high resistance to ampicillin , ampicillin/sulbactam, cefazolin, ceftriaxone, cefotetan and nitrofurantoin with resistant rates of 67.20%-100.00%. Drug resistance rates to other β-lactams, fluoroquinolones, aminoglycoside, compound sulfamethoxazole and minocycline were significantly higher in carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa strains than those in non-carbapenem-resistant strains , and the differences were statistically significant (P <0.05 or <0.01).Stenotrophomonas maltophilia and Burkholderia cepacia strains were only sensitive to levofloxacin , compound sulfamethoxazole and minocycline . Klebsiella pneumonia (89 strains), Escherichia coli (80 strains) and Enterobacter cloacae (25 strains) were top 3 enterobacteriaceae , which were almost completely resistant to ampicillin , but were sensitive to piperacillin/tazobactam , cefoperazone/sulbactam , amikacin and carbapenems ( with resistant rates <15%) .More than 50%strains of extended spectrum β-lactamases ( ESBLs )-producing Klebsiella pneumonia and Escherichia coli were moderately or highly resistant to ampicillin/sulbactam , most cephalosporins ( except cefotetan and cefoperazone/sulbactam ), gentamycin, tobramycin, fluoroquinolones, aztreonam, compound sulfamethoxazole and minocycline , and the resistant rates were higher than those in non-ESBLs-producing strains (P <0.05 or <0.01).Conclusions Nonfermentative bacteria and enterobacteriaceae are the most prevalent gram-negative bacterial pathogens in lower respiratory tract infections in patients with AECOPD . Carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa strains, as well as ESBLs-producing Klebsiella pneumonia and Escherichia coli strains are highly resistant to most antibacterial agents .

OBJECTIVE: To investigate the correlation betwen varying degrees of non-acute tinnitus and anxiety and depression. METHOD: Seventy-seven outpatients with non-acute tinnitus as their in chief complaint were submitted to Tinnitus Handicap Inventory(THI), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS). RESULT: THI and its three subscales were found to have significant correlations with SAS and SDS. The group (THI ≥ 38) had more anxiety and depression than the mild (THI < 38). Significant correlations were also observed between THI, SAS and SDS in the group with THI ≥ 38, in contrast with the group of THI < 38. CONCLUSION Patients with THI ≥ 38 suffered from severe anxiety and depression than the mild. Doctors should pay more attention to these patients, especially their psychological disorders.

Clinicopathological data of 15 patients with pyloric early cancer and precancerous lesions, who received endoscopic submucosal dissection (ESD) in Zhejiang Cancer Hospital from March 2011 to January 2020 were retrospectively analyzed. Postoperative pathology showed 7 cases of low-grade intraepithelial neoplasia, 3 cases of high-grade intraepithelial neoplasia, and 5 cases of early gastric cancer. R0 complete resection was achieved in all patients. The mean operation time was 55.2 min (35-78 min). One patient had delayed postoperative bleeding, and no other complications such as bleeding, perforation or abdominal pain occurred in other 14 patients. No recurrence, metastasis or pyloric stenosis was found during the follow-up of 31.3 months (1-106 months). ESD is safe and effective for early cancer and precancerous lesions in the pylorus.

Objective:To evaluate the potential effects of serum lipid levels, appendicular skeletal muscle mass index (ASMI) and body mass index (BMI), together with its dynamic changes, on tumor progression in renal clear cell carcinoma patients, so as to inform body weight management.Methods:This prospective cohort study included a total of 100 patients with high-risk clear cell renal cell carcinoma. Serum lipid levels were detected, ASMI and BMI were measured using bioelectrical impedance analysis and the dynamic changes of BMI were tracked. The effects of BMI, ASMI and serum lipid levels on tumor progression within 2 years were explored.Results:Patients with normal BMI and low ASMI had 5.248 (95% CI: 1.946 to 14.153, P = 0.001) times higher risk of tumor progression than those who were overweight or obese. For every 0.1-unit increase in pre-operative HDL-C, the risk of tumor progression decreased by 0.771 (95% CI: 0.631 to 0.942, P = 0.011) times. Patients who experienced more than 5% decrease in BMI compared with baseline had 5.165 (95% CI: 1.735 to 15.370, P = 0.003) times the progression risk of patients whose BMI changed within ±5% from baseline. Conclusions:The advantage of obese clear cell carcinoma patients over normal-weight patients in tumor progression-free survival may be influenced by ASMI, pre-onset involuntary weight loss and lipid levels. Therefore, patient weight management should not merely focus on absolute BMI but tailor to individual characteristics, including cancer stage, body composition and metabolic status.

The clinico-pathological data of 539 patients who underwent laparoscopic LAR of rectal cancer in 13 medical centers, including 248 cases in Renji Hospital of Shanghai Jiaotong University School of Medicine, 35 cases in Ningbo First Hospital, 35 cases in Changzhou Second People's Hospital, 32 cases in the First People's Hospital of Nantong, 32 cases in Linyi People's Hospital, 31 cases in Changzhou Wujin People's Hospital, 28 cases in Jiading District Hospital of Traditional Chinese Medicine, 27 cases in the First Hospital of Taizhou, 26 cases in Shanghai Pudong Gongli Hospital, 21 cases in the People's Hospital of Rugao, 11 cases in Central Hospital of Fengxian District, 7 cases in Ningbo Hangzhou Bay Hospital and 6 cases in Jiangsu jianhu People's Hospital, from January 2016 to November 2020 were collected. There were 157 males and 382 females, aged (62.7±0.5)years. Observation indicators: (1) follow-up; (2) risk factors for anastomotic leakage after laparoscopic LAR; (3) establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. Follow-up was conducted by outpatient examination or telephone interview. Patients were followed up at 1 week after discharge or 1 month after the operation to detect the anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test and multivariate analysis was conducted usong the Logistic regression model. The area under curve of receiver operating characteristic curve was used to estimate the efficiency of detecton methods. The maximum value of the Youden index was defined as the best cut-off value. Results:(1) Follow-up: 539 patients were followed up at postoperative 1 week and 1 month. During the follow-up, 79 patient had anastomotic leakage, with an incidence of 14.66%(79/539). Of the 79 patients, 39 cases were cured after conservative treatment, 40 cases were cured after reoperation (ileostomy or colostomy). (2) Risk factors for anastomotic leakage after laparoscopic LAR. Results of univariate analysis showed that sex, age, body mass index, smoking and/or drinking, tumor diameter, diabetes mellitus, hemoglobin, albumin, grade of American Society of Anesthesio-logists (ASA), neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line, the number of pelvic stapler, reinforced anastomosis, volume of intraoperative blood loss, placement of decompression tube, preservation of left colic artery, operation time and professional doctors were related factors for anastomotic leakage after laparoscopic LAR ( χ2=14.060, 4.387, 5.039, 4.094, 17.488, 33.485, 25.066, 28.959, 34.973, 34.207, 22.076, 13.208, 16.440, 17.708, 17.260, 4.573, 5.919, 5.389, P<0.05). Results of multivariate analysis showed that male, tumor diameter ≥3.5 cm, diabetes mellitus, hemoglobin <90 g/L, albumin <30 g/L, grade of ASA ≥Ⅲ, neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line <1 cm, the number of pelvic stapler ≥3, non-reinforced anastomosis, volume of intraoperative blood loss ≥100 mL and no placement of decom-pression tube were independent risk factors for anastomotic leakage after laparoscopic LAR ( odds ratio=2.864,3.043,12.556,7.178,8.425,12.895,8.987,4.002,3.084,4.393,3.266,3.224,95% confidence interval as 1.279?6.411, 1.404?6.594, 4.469?35.274, 2.648?19.459, 2.471?28.733, 4.027?41.289, 3.702?21.777, 1.746?9.171, 1.365?6.966, 1.914?10.083, 1.434?7.441, 1.321?7.867, P<0.05). (3) Establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. based on the results of univariate analysis, clinicopathological factors with χ2>20, χ2>10 and ≤20 or χ2≤10 were defined as scoring of 3, 2, 1, respectively. The cumulative clinicopatho-logical factors scoring ≥6 was defined as an effective evaluating indicator for postoperative anastomotic leakage. The risk assessment scoring model (6-321) for anastomotic leakage after laparoscopic LAR was established. The cumulative value ≥6 indicated high incidence of anastomotic leakage, and the cumulative value <6 indicated low incidence of anastomotic leakage. Conclusions:Male, tumor diameter ≥3.5 cm, diabetes mellitus, hemoglobin <90 g/L, albumin <30 g/L, grade of ASA ≥Ⅲ, neo-adjuvant chemoradiotherapy, distance from anastomotic level to dentate line <1 cm, the number of pelvic stapler ≥3, non-reinforced anastomosis, volume of intraoperative blood loss ≥100 mL and no placement of decompression tube are independent risk factors for anastomotic leakage after laparoscopic LAR. The risk assessment scoring model (6-321) is established according to the above results.The cumulative value ≥6 indicates high incidence of anastomotic leakage and the cumulative value <6 indicates low incidence of anastomotic leakage.
