The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective To evaluate the clinical value of Fluorine-18-fluorodeoxyglucose (18F-FDG) positron-emission temography-computed tomography (PET-CT) examination in intrahepatic cholangiocarcinoma (ICC) staging.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 190 patients with ICC who were admitted to the Eastern Hepatobiliary Surgery Hospital Affiliated to Naval Military Medical University from September 2013 to June 2016 were collected.There were 107 males and 83 females,aged from 37 to 79 years,with an average age of 57 years.There were 90 cases without distant metastasis undergoing surgery treatment and 100 with distant metastasis undergoing non-surgical treatment.Patients underwent preoperative CT,magnetic resonance imaging (MRI),and PET-CT examination,and then received surgery or non-surgery according to preference of patients and their family members.Observation indicators:(1) imaging features on preoperative CT,MRI,PET-CT examination;(2) treatment;(3) evaluation of tumor diameter,multiple tumors,macrovascular invasion,and bile duct invasion by three examinations in ICC staging of patients undergoing operation;(4) evaluation of regional lymph node metastasis by three tests in ICC staging of patients undergoing operation;(5) evaluation of distant metastasis in ICC staging by three tests.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was analyzed by single factor ANOVA and paired comparison was analyzed by SNK method.Measurement data with skewed distribution were described as M (range).Count data were described as absolute number or percentage,and comparison between groups was analyzed using the chi square test.Results (1) Imaging features on preoperative CT,MRI,PET-CT examination:all the 190 patients received routine upper abdominal CT,MRI,and systemic PET-CT examination before treatment.CT imaging of ICC showed inhomogeneous low density on plain scan,peripheral enhancement in arterial phase,persistent enhancement of tumor margin in portal phase,and sometimes mild to moderate centripetal enhancement.MRI imaging showed heterogeneous low signal on T1-weighted imaging,uneven high,and slightly high signal on T2-weighted imaging.Reinforcement on MRI is the same as CT.Transverse images,fusion transverse images and maximum intensity projection images of PET-CT imaging showed abnormal high FDG uptake around the tumor.(2) Treatment:81 out of the 90 ICC patients with surgery treatment underwent hepatectomy and lymphadenectomy,and 9 underwent only tumor tissue biopsy and lymph node biopsy due to intraoperative finding of abdominal metastasis.Of the 100 non-operated patients,30 received systemic chemotherapy,23 received local radiotherapy,and 47 gave up treatment.(3) Evaluation of tumor diameter,multiple tumors,macrovascular invasion,and bile duct invasion by three examinations in ICC staging of patients undergoing operation:the tumor diameters of ICC on CT,MRI and PET-CT were (6.8±2.8)cm,(6.9±2.9)cm,(7.2±2.8)cm,respectively.There was no significant difference among the three methods (F=0.085,P＞0.05).CT,MRI,PET-CT had similar accuracy of 80.0％ (72/90),78.9％ (71/90),72.2％ (65/90) on diagnosing multiple tumors,87.8％(79/90),92.2％ (83/90),94.4％ (85/90) for macrovascular invasion,and 93.3％ (84/90),95.6％ (86/90),96.7％ (87/90) for vascular and bile duct invasion,respectively,there was no significant difference in the above indicators between the three groups (x2 =1.801,2.662,1.131,P＞0.05).(4) Evaluation of regional lymph node metastasis by three examinations in ICC staging of patients undergoing operation:the accuracy of CT,MRI and PET-CT examination for lymph node metastasis was 62.2％ (56/90),68.9％(62/90),86.7％ (78/90) and sensitivity was 40.0％ (16/40),47.5％ (19/40),80.0％ (32/40),respectively,showing significant differences between the three groups (x2 =14.446,14.666,P＜0.05),showing a significant difference between CT and PET-CT examination (x2=14.134,13.333,P＜0.05),showing a significant difference between MRI and PET-CT examination (x2=8.229,9.141,P＜0.05).The sensitivity of CT,MRI and PET-CT examination for lymph node metastasis was 80.0％ (40/50),86.0％ (43/50),92.0％ (46/50),showing no significant difference between the three groups (x2=2.990,P＞0.05).(5) Evaluation of distant metastasis in ICC staging by three tests:there were 27,34 and 100 cases with distant metastasis evaluated by CT,MRI and PET-CT examination,including 40 with supraclavicular lymph node metastasis,32 with bone metastasis,30 with mediastinal lymph node metastasis,20 with hilar lymph node metastasis,17 with pulmonary metastasis;77 patients had more than 2 sites of metastasis.The accuracy of CT,MRI and PET-CT examination for distal metastasis in 190 ICC patients was 61.58％ (117/190),65.26％ (124/190),98.42％ (187/190),respectively,with a significant difference between the three groups (x2=83.639,P＜0.05),with a significant difference between CT and PET-CT examination (x2=80.592,P＜0.05),between MRI and PET-CT examination (x2=70.284,P＜ 0.05).Conclusion PET-CT examination makes up for the deficiency of CT and MRI in judging regional lymph node metastasis and distant metastasis,and contributes to the clinical staging of ICC.

ObjectiveTo investigate clinical symptoms and influencing factors of food intolerance and to identify susceptibility of food intolerance among adults with various Traditional Chinese Medicine (TCM) constitutions.MethodsA total of 411 individuals were recruited by using simple sampling method.ELISA was used to test serum levels of food intolerance specific IgG antibody.TCM constitution,food intake habit,lifestyle,and biochemical data were collected.Results ( 1 ) The prevalence of food intolerace was 60.1％ (247/411).(2) The most commonly seen food intolerance specific IgG were those against egg (44.9％ ),crab ( 37.7％ ),or cod ( 23.1％ ).Intolerance to 1 to 5 kinds of food could be found in single individual.Subhealthy people were more likely to suffer from food intolerance ( P＜0.05 ).( 3 ) Those with food intolerance always presented with various symptoms,mainly respiratory system symptoms.(4) The most common types of TCM constitution of the participants were gentleness constitution,qi-insufficiency constitution,yang-deficiencyconstitution,anddampness-heatconstitution.Thoseofnon-bloodstasis constitution were more likely to suffer from crab intolerance ( P＜0.05 ).Conclusion The prevalence of food intolerance is relatively high in Fuzhou areas.Subhealthy status,obesity women,and pathological constitutions may be risk factors of food intolerance.

A model of hypoxic pulmonary hypertension (HPH) was reproduced in rats by exposing them to chronic hypoxia environment corresponding to 5km level. At 10d,20d, 30d after hypoxia in hypoxia groups and control group, the pulmonary vascular structural changes were observed with optical microscope, histochemistry and electronic microscope. The changes in hypoxia groups were as follows: ①the wall of small pulmonary arteries of every calibre showed marked thickening compared with that in control group, and the main changes involved smooth muscle cells(SMC)proliferation and collagen deposition in the vessels wall; ② SMC proliferation, muscularization of non myocytic arteries and partial myocytic arteries were observed in intra acinar pulmonary arteries, so the counts of muscular arteries significantly increased compared with control group( P
