[Survival in Lung Cancer among Female Never-smokers in Rural Xuanwei and Fuyuan Counties in Eastern Yunnan Province, China].

Background: Lung cancer rates among women in rural Xuanwei and Fuyuan counties in eastern Yunnan province, China, are among the highest in the world, even though almost all women are non-smokers, and they tend to develop lung cancer at a younger age than other locations by roughly 5 yr-10 yr. This study investigated the survival of lung cancer patients among female never-smokers.

Methods: The female never-smokers, who had lived for many years in Xuanwei and Fuyuan counties, with lung cancer newly-diagnosed between July 2006 to March 2010, were followed up through the end of 2016.

Laryngeal electromyography-guided hyaluronic acid vocal fold injection for unilateral vocal fold paralysis: a prospective long-term follow-up outcome report.

Importance: Unilateral vocal fold paralysis (UVFP) is a common voice disorder that may cause glottal closure insufficiency with hoarseness of voice. Laryngeal electromyography (LEMG)-guided hyaluronic acid vocal fold (VF) injection has been proposed as a treatment option to improve glottal closure with a satisfactory short-term effect. To our knowledge, this study reports the first long-term follow-up result of this treatment modality.

[Molluscicidal effect of Rongbao in Mianyang City].

Objective: To evaluate the molluscicidal effect of Rongbao in schistosomiasis endemic areas in Mianyang City.

Methods: Three Oncomelania hupensis snail habitats with the similar snail status were selected and sprayed with Rongbao, niclosamide, and fresh water, respectively. Then the snail status in the three fields was surveyed before the spraying and 7, 15, 30 and 60 days after the spraying, and the molluscicidal effects of different molluscicides were compared.

[Toxicity of 50% ethanol salt powder of niclosamide on growth of silkworms].

Objective: To observe the toxity of niclosamide on the growth of silkworms.

Methods: Mulberry leaves were soaked in the different concentrations of solution of 50% ethanol salt powder of niclosamide for 10 s or 3 min, and then the leaves were fed to silkworms. The death rates of silkworms and the weight of cocoons were observed.

The learning curve for laparoscopic splenectomy for massive splenomegaly: a single surgeon's experience.

Background: Laparoscopic splenectomy (LS) for massive splenomegaly is more technically challenging than for a normal-sized spleen. The purpose of this study was to determine the effect of operative experience on perioperative outcomes of LS for massive splenomegaly.

Methods: Between January 2008 and December 2010, 36 consecutive patients who were diagnosed with massive splenomegaly underwent LS in our department.

Laryngeal electromyography-guided hyaluronic acid vocal fold injection for unilateral vocal fold paralysis--preliminary results.

Objectives: The purpose of this study is to investigate the feasibility of using an injectable needle electrode to guide hyaluronic acid (HA) vocal fold injection (VFI) during laryngeal electromyography (LEMG) for unilateral vocal fold paralysis (UVFP).

Study Design: Prospective study.

Methods: From March to June 2010, 20 UVFP patients received LEMG examination at our clinic.

The basis of preoperative vocal fold paralysis in a series of patients undergoing thyroid surgery: the preponderance of benign thyroid disease.

Background: Preoperative vocal fold paralysis (VFP) is thought to be rare in patients with benign thyroid disease (BTD). In contrast with cases of malignancy, in which the recurrent laryngeal nerve (RLN) should be severed, in patients with BTD and VFP the RLN can be preserved without threatening patients' lives. This study investigates the clinical features that enable identification of patients who have VFP associated with BTD.

Association of heartburn and laryngopharyngeal symptoms with endoscopic reflux esophagitis, smoking, and drinking.

Objectives: This study was conducted to investigate the association of laryngopharyngeal symptoms and heartburn with endoscopic esophagitis, smoking, and drinking. The clinical importance of the Reflux Symptom Index (RSI) in predicting endoscopic esophagitis was also evaluated.

Study Design: Case series with planned data collection.

[Mental health assessment among scattered residents after Wenchuan earthquake in Anxian, Sichuan province].

Objective: To explore the mental health status of residents scattered living in Anxian after Wenchuan earthquake so as to provide scientific basis for further mental health intervention.

Methods: A face to face interview was conducted among the scattered residents with designed questionnaire, which had three parts of the physical and emotional reaction, the relax methods and the social care and supports expected. Two-stage probability proportional to size (PPS) sample method was performed to sample 2184 from 0.

[Public health situation and needs assessment after Wenchuan earthquake in Anxian, Sichuan province].

Objective: To explore the public health situation and needs in Anxian after Wenchuan earthquake so as to make an effective strategy for disease control and prevention.

Methods: 69 concentrated settlements with 100 residents were investigated. Probability proportion to size was adopted for sampling of 2200 residents from 687 scattered households (about 440 000 scattered residents).

Prognostic indicators of unilateral vocal fold paralysis.

Objectives: To determine the possible prognostic indicators of unilateral vocal fold paralysis (UVFP) and survey the timing and values of preset laryngeal electromyography (LEMG) rules for UVFP.

Design: Cohort study with retrospective data analysis.

Setting: Voice clinic of a tertiary medical center.

Cervical sympathetic chain schwannoma.

Schwannomas are benign, slow-growing tumors that arise from Schwann cells of the nerve sheath. Those originating from the sympathetic cervical chain are rare. Herein, we present three cases of cervical sympathetic chain schwannoma (CSCS) and describe our experience with the clinical presentation, surgical management, and outcomes of patients with this pathology.
