Objective To observe the efficacy ofHuayu Kangyou Formula combined with Western medicine for Hp-related peptic ulcer disease;To discuss the mechanism of action.Methods Totally 152 patients were randomly divided into treatment group and control group, 76 cases in each group. Control group was given standard triple therapy, while treatment group was givenHuayu Kangyou Formula based on the standard triple therapy. The treatment lasted for 6 weeks. The clincal symptom scores and gastroscopy were observed to evaluate the therapeutic effect, adverse reactions were recorded, and relapse of ulcer was followed-up.Results The total effective rates of clinical symptoms in the treatment group and the control group were 94.74% (72/76) and 84.21% (64/76), respectively;the excellent rates were 78.95% (60/76) and 55.26% (42/76), respectively;the incidences of adverse reactions were 5.26% (4/76) and 13.16% (10/76), respectively;the relapse rates after 1 year of follow-up visit were 13.63% (6/44) and 41.67% (10/24), respectively, with statistical significant difference between the two groups (P<0.05).ConclusionHuayu Kangyou Formula combined with Western medicine can effectively improve the efficacy of Hp-relative peptic ulcer disease, reduce adverse reaction rate and relapse rate.

Objective To explore the clinical characteristics and risk factors of occult pneumonia in advanced elderly patients.Methods A total of 170 advanced elderly patients with community-acquired pulmonary infection in geriatric department of Xijing hospital from January 2014 to October 2017 were enrolled.Patients were divided into two groups:the observation group (with occult pneumonia,n=80)and the control group(without occult pneumonia,n =90).Clinical data of patients were collected,and clinical characteristics and related risk factors of occult pneumonia in elderly patients were analyzed.Results There was no statistically significant difference in the positive rate of sputum culture and the distribution of pathogenic bacteria between the two groups (P ＞ 0.05).Gram-negative bacteria predominated in pathogenic bacteria.The hospitalization time was longer in the observation group than in the control group[(17.3 ± 3.0) d vs.(10.3 ± 3.9) d,P ＜ 0.05].The mortality rate was higher in the observation group than in the control group(10.0 ％ vs.3.3 ％,P ＜ 0.05).The age was older in the observation group than in the control group[(87.0± 1.7) years vs.(82.0± 2.4) years,P ＜ 0.05].The incidences of diabetes,Alzheimer's disease,hypothyroidism and long-term bed rest were higher in the observation group than in the control group (P ＜ 0.05).Multivariate logistic regression analysis showed that age (OR =6.93),dementia (OR =4.32),hypothyroidism(OR =4.89) were independent risk factors for occult pneumonia (P ＜ 0.05).Conclusions The pathogenic bacteria in advanced elderly patients with occult pneumonia are mainly gram-negative bacteria.The positive rate of CT scan confirmed-occult pneumonia is much higher than that by chest X-ray.The advanced elderly patients with occult pneumonia have longer hospitalization time and higher mortality rates.Old age,senile dementia and hypothyroidism are independent risk factors for occult pneumonia in advanced elderly patients.
