Objeetive To study the therapeutic effect of the H2 antagonist fomotidine on preventing weight gain olanzapine-induced.Methods Forty first-episode CCMD-3 schizophrenia patients were randomly allocated to received either famotidine or placebo in addition to olanzapine for 8 weeks.Their body weights and heights were measured before treatment and 2 weeks,4 weeks,8 weeks after treatment to calculate the body mass index and the percentage of patients gained more than 7% of initial bpdy weight after 8 weeks.SAPS and SANS were selected to evaluate the therapeutic effect.Results While the weight and the body mass index of patients in two groups after 2 weeks,4 weeks,8 weeks post-treatment increased significantly compared with those of pre-treatment(P＜0.05).The weight of patients in two groups gained 3.7kg at the edd of 8 weeks,and the BMI increased 2.5 or 2.6 kg/cm2,reapectively.However 8 weeks later,the difference between two groups wan not significant(P＞0.05).The difference between two groups on the percentage of patients gained more than 7% of initial body weight at the end of 8 weeks Wan not significant(P＞0.05).The sCOres of SAPS and SANS at the end of 8 weeks decreased significantly compared with those of the baseline(P＜0.05),but the difference between two groups was not significant(P＞0.05).Conclusion Allocated to the H2 antagonist fomotidine could not reduce weight gain olanzapine-induced.

ObjectiveTo compare the effect of imagings taken with different angles to observe relationship of wrist joint and distal screws.Methods29 patients with the distal radius fractures were performed operatively with the open reduction and internal fixation. The standard antero-posterior and lateral imagings of the wrist joint were taken during operation, and two different angle imagings of the wrist joint were also taken meantime in all 29 patients.ResultsScrews were found to penetrate into the joint in antero-posterior imagings of 23 cases and standard lateral imagings of 25 cases. However, no screws were found to penetrate into the joint in two different angle imagings.ConclusionTwo different angle imagings can fully show the articular surface of distal radius without screws.

To present the clinical characteristics and the misdiagnosis rate of acute coronary syndrome manifested primarily as throat discomfort, we conducted a multicentric and retrospective study in the cardiology and otorhinolaryngology departments. Records of patients with primary complaint of throat discomfort, absence of chest pain at onset, and an ultimate diagnosis of acute coronary syndrome, as well as patients with pharyngitis (as controls) were collected from May 2015 to April 2016. The patients' main manifestations were compared. Logistic regression results showed that chest tightness, dyspnea, perspiring, and exertional throat symptoms were significantly associated with acute coronary syndrome, with odds ratios of 8.3 (95% CI 2.2-31.5), 10.9 (95% CI 1.8-66.9), 25.4 (95% CI 3.6-179.9), and 81.2 (95% CI 13.0-506.7). A total of 25 (56.82%) out of 44 acute coronary syndrome patients, who were first admitted to the otorhinolaryngology department, were misdiagnosed, with a 12% (3/25) mortality rate. Throat discomfort can be the principal manifestation of acute coronary syndrome. Such patients exhibit high misdiagnosis and mortality rates. Exertional throat symptoms, chest tightness, perspiring, and dyspnea were important indicators of acute coronary syndrome in patients whose main complaint was throat discomfort. The awareness of this condition will result in prompt diagnosis and reduce morbidity and mortality.
