Objective:To observe the effect of rapid point pressure on clinical effect and pulmonary function of patients with chronic persistent bronchial asthma.
Methods:A total of 60 confirmed chronic persistent bronchial asthma cases were randomly allocated into two groups, 30 in each group. Cases in the treatment group were treated with rapid point pressure, 1 h for the initial treatment, and 40 min for the ensuing treatments. The treatment was done once a day for 40 d. Cases in the control group were treated with Compound Methoxyphenamine Hydrochloride Capsules, 2 capsules for each dose, 3 times a day. The treatment lasted for 7 consecutive days. A 1-year follow-up was made for both groups.
Results:After treatment, the scores of each symptom and total symptom scores for the traditional Chinese medicine (TCM) symptoms in the treatment group were significantly higher than those in the control group (P<0.05);the total effective rates in the treatment group were higher than those in the control group in each time frame; and there was a between-group statistical significance in total effective rate after 7 d of treatment (P<0.01). After 40-day treatments, there were statistical significances in the forced expiratory volume in 1 s percentage of predicted value (FEV 1%) and inspiratory capacity (IC%) in the treatment group (P<0.05); however, there were no statistical significances (P>0.05) in forced expiratory volume in 1 second to forced vital capacity ratio (FEV1/FVC), peak expiratory flow rate (PEF%) and maximum midexpiratory flow rate (MMEF%); and there were no statistical significances in pulmonary function parameters in the control group. In addition, as for pulmonary function parameters, there were no intra-group statistical significances in differences before and after treatment (P>0.05).
Conclusion:Rapid point pressure can alleviate patients’ TCM symptoms and improve their FEV%and IC%.

Objective:To observe the effect of breathing andDaoyin exercises on the quality of life in patients with stable chronic obstructive pulmonary disease (COPD) due to deficiency of the lung and kidney (grade II-III).
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) by random number table. Cases in the control group received routine Western medical treatment, whereas cases in the treatment group conducted breathing andDaoyin exercises in addition to routine Western medical treatment. Patients in both groups were treated for a total of 3 months. Then the observation was made on changes in pulmonary ventilation function, major clinical symptoms, modified Medical Research Council scale (mMRC), distance in 6-minute walk test (6-MWT), COPD assessment test (CAT) and efficacy satisfaction questionnaire for COPD (ESQ-COPD) before and after treatment.
Results:After treatment, the total effective rate was 80.0% in the treatment group, versus 66.7% in the control group, showing a statistical difference (P<0.05). Patients in the treatment group obtained more significant improvement in coughing, sputum production, dyspnea and shortness of breath than those in the control group (P<0.05). Patients in the treatment group obtained more significant elevation in the forced expiratory volume in 1 second percentage of predicted value (FEV1%) and peak expiratory flow rate (PEF%) than those in the control group (P<0.05). Patients in the treatment group obtained lower mMRC score than those in the control group (P<0.05). Patients in the treatment group obtained longer 6-MWT distance than those in the control group (P<0.05). Patients in the treatment group obtained lower CAT score (P<0.01) and higher ESQ-COPD score (P<0.05) than those in the control group.
Conclusion:Breathing andDaoyin exercises combined with routine Western medical treatment are effective for stable COPD (grade II-III) due to deficiency of the lung and kidney and can improve the patients’ quality of life.

Objective:To observe the clinical effect of acupuncture on chronic obstructive pulmonary disease (COPD), and the improvements of patients’ pulmonary ventilation function and 6-minute walk test (6-MWT) distance. Methods:A total of 80 COPD patients [grade 3-4 in Global Initiative for Chronic Obstructive Lung Disease (GOLD), qi deficiency of the lung and kidney in traditional Chinese medicine (TCM) pattern] were randomly allocated into a treatment group (n=40) and a control group (n=40). Salmeterol Xinafoate and Fluticasone Propionate powder (Seretide,50μg/250μg) for inhalation was used for basic treatment in both groups (once in the morning and once in the evening). Patients in the treatment group received acupuncture at Feishu (BL 13), Shenshu (BL 23), Qihai (CV 6), Guanyuan (CV 4), Dingchuan (EX-B 1), Danzhong (CV 17) and Zusanli (ST 36) twice a week for 3 months. After 3 months of treatment, clinical effects, lung ventilation functions and 6-MWT distance were observed and compared in the two groups. Results:After 3 months of treatment, the total effective rate was 95.0% in the treatment group, versus 80.0% in the control group, showing a statistical difference (P<0.05); the phlegm expectoration, dyspnea and shortness of breath were more significantly improved in the treatment group than those in the control group (P<0.01,P<0.05); and the 6-MWT distance and forced expiratory volume in 1 second percentage of predicted value (FEV1%) were more significantly improved in the treatment group than those in the control group (P<0.05,P<0.01). Conclusion:Seretide inhaler combined with acupuncture can improve signs and symptoms in COPD patients, increase the 6-MWT distance, improve FEV1% and obtain better results than Seretide alone.

Objective To evaluate the efficacy of TCM Bufei Yishen method combined with conventional western medicine for patients with stable chronic obstructive pulmonary disease (COPD) presenting lung-kidney deficiency.Methods Sixty six COPD patients with lung-kidney deficiency admitted from January 2014 to December 2015 were randomly divided into Bufei Yishen (BY) group (n=34) and control group (n=32).Patients in control group treated with conventional western medicine and those in BY group were treated with TCM Bufei Yishen recipe combined with conventional western medicine.The pulmonary function and COPD Assessment Test (CAT) score were evaluated before and after treatment,and after 3 month-following up.Results In BY group the pulmonary function parameters FEV1 and FEV1/FVC after treatment were significantly higher than those before treatment (69.91±8.15 vs.51.56 ± 8.33,t=4.435,P< 0.01;57.33 ± 9.86 vs.49.89 ± 8.89,t=3.526,P<0.05,respectively);the FEV1 and FEV1/FVC after 3-momth follow up were significantly higher than those before treatment (65.68±9.54 vs.51.56±8.33,t=3.993,P<0.05;59.08±8.49 vs.49.89±8.89,t=3.668,P<0.05,respectively).In control group the FEV1 and FEV1/FVC after 3-momth follow up were significantly higher than those before treatment (63.94±8.76 vs.50.98±8.08,t=4.475,P<0.05;59.12±9.55 vs.50.35±9.06,t=3.614,P<0.05,respectively).The pulmonary function parameters FEV1 of BY group was significantly better than that of control group (69.91±8.15 vs.62.02±8.91,t=3.745,P<0.05) after 3-months of follow-up.After treatment,the CAT score in both group was decreased (BY group: 27.35±2.93 vs.30.36±3.19,t=3.548,P<0.05;control group: 29.06±2.67 vs.30.51±2.99,t=1.832,P<0.05);however,the CAT score was decreased more markedly in BY group than that in control group (t=2.658,P<0.05).Conclusion TCM Bufei Yishen method combined with conventional western medicine can improve the pulmonary function and quality of life of patients with stable COPD presenting lung-kidney deficiency.

Objective:To analyze Traditional Chinese Medicine(TCM) prescriptions in COVID-19 patients in Shanghai area.Methods:Two hundred and forty patients were enrolled in the study, including 19 mild cases, 199 moderate cases, 16 severe case and 6 critical cases. The COVID-19 formula in Shanghai area was extracted and input in TCM Inheritance platform. Data association method such as software association rules,improved mutual information method,complex system entropy clustering,unsupervised entropy hierarchical clustering were used to analyze the frequency,herb flavor and meridian, combination rule and core combination of different types of Chinese herbs in the treatment of COVID-19 in Shanghai area.Results:According to the frequency analysis of 240 prescriptions of Chinese medicine,194 herbs were found. The COVID-19 formula herbs were all "cold", the frequency of use in mild, moderate, severe and critical cases was [46.02%(104/226), 46.31%(1 230/2 656), 37.06%(146/394), 39.24%(31/79)]. The flavor was mainly "bitter" and the frequency of use in 4 types of disease were [36.53%(122/332), 37.33%(1 445/3 857), 35.96%(205/564), 33.62%(39/113)]. Scutellaria was the most frequently used TCM of "bitter and cold". The drugs used were mainly lung,stomach and spleen meridians. By comparing the formulas between mild and moderate cases,herb combinations with the highest frequency were all "scutellaria glycyrrhiza" and "tangerine glycyrrhiza". The formulas for 19 mild cases were collected,and 197 drug combinations were counted, and 125 Chinese medicine association rules,including 13 Chinese herbs. The formulas were extracted in 199 moderate cases of COVID-19, a total of 92 drug combinations and 38 Chinese medicine association rules were collected,including 19 Chinese herbs. In 16 severe cases, a total of 62 drug combination models and 46 Chinese medicine association rules were collected,including 17 Chinese herbs. For the 6 critical cases,80 Chinese medicine prescriptions were combined,and 10 Chinese medicine association rules, including 12 Chinese herbs.Conclusions:The herbal prescriptions of COVID-19 in Shanghai are characterized by clearing away heat and resolving dampness. By analyzing prescription rules with complex system entropy clustering, association compatibility ideas of different types of traditional Chinese medicine are found to be different among four types of COVID-19 cases. Analyzing the connection rules in formulas, by using the theory of TCM and pharmacology of traditional Chinese medical formula in different COVID-19 patients may be helpful for general practitioners.

Objective To investigate the epidemiological characteristics,clinical features,diagnosis,treatment and prognosis of benign tumor of the bile ducts.Methods The retrospective cross-sectional multicenter study was conducted.The clinical data of 136 patients with benign tumor of the bile ducts who were admitted to the eight hospitals between January 2007 and December 2016 were collected,including 70 in the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University,19 in the First Affiliated Hospital of Zhengzhou University,15 in the First Affiliated Hospital of Xi'an Jiaotong University,11 in the First Affiliated Hospital of Dalian Medical University,7 in the Affiliated Hospital of North Sichuan Medical College,6 in the Southwest Hospital of the Third Military Medical University,4 in the Cancer Center of Sun Yat-Sen University and 4 in the Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine.All the patients received laboratory and imaging examinations,and then underwent corresponding surgery when treatment planning was respectively determined by comprehensive hospitals according to clinical features and results of examinations.Surgical procedures were performed based on the results of intraoperative frozen section in rapid pathological diagnosis.Observation indicators:(1) epidemiological characteristics;(2) clinical features;(3) results of laboratory and imaging examinations;(4) treatment situations;(5) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the survival of patients up to March 2017.Measurement data with normal distribution were represented as-x±s.Results (1) Epidemiological characteristics:Of 136 patients,the male to female ratio was 1.78 ∶ 1.The incidence of whole bile duct tumors was from high to low,including 52 patients with duodenal papilla adenoma,32 with extrahepatic bile duct adenoma,24 with intrahepatic biliary cystadenoma,11 with intrahepatic papillary adenoma,9 with intrahepatic bile duct epithelial tumor,7 with epithelial tumor of duodenal papilla and 1 with neuroendocrine tumor of duodenal papilla.Among 136 patients,adenomas (including cystadenoma) was detected in 108 patients,papillomas in 11 patients,intraepithelial neoplasias in 16 patients,neuroendocrine tumor in 1 patient;intrahepatic bile duct benign tumors in 44 patients and extrahepatic bile duct (including duodenal papilla) benign tumors in 92 patients.(2) Clinical features:of 44 patients with intrahepatic bile duct benign tumors,29 had abdominal pain,fever and abdominal masses,4 had jaundice,11 had no obvious clinical symptoms and were diagnosed by physical examination.Among 92 patients with extrahepatic bile duct benign tumors,76 developed obstructive jaundice,68 were accompanied by abdominal pain or colicky pain,8 were combined with pancreatitis and 2 deveIoped hemobilia,some patients were combined with multiple clinical symptoms.(3) Results of laboratory and imaging examinations:82 patients received CA19-9 test,results of 22 patients were abnormal,with a level of (148-± 126)U/mL.Ninety-seven patients received carcinoembryonic antigen (CEA) test,with a level of test of (2.7±2.0) μg/L,and a level of CEA in 1 patient was slight abnormal,with a level of 11.2 pμg/L.One hundred and thirty-six patients underwent preoperative ultrasound examinations,showing unqualified hepatic and bile duct space occupying lesions and bile duct dilatation.Ninetyfive patients underwent preoperative computed tomography (CT),80 underwent preoperative magnetic resonance imaging (MRI) or magnetic resonanced cholangio-pancreatography (MRCP),and 13 underwent preoperative endoscopic ultrasonography (EUS).Twenty-nine patients were considered for intrahepatic bile duct benign tumors;76 were diagnosed with obstructive jaundice,with uncertain benign or malignant tumors;other patients had bile duct space occupying,considering bile duct tumor (including cancer).Twelve patients with bile duct obstruction underwent ERCP,showing obstruction site and morphology.(4) Treatment situations:among 136 patients,65 underwent pancreaticoduodenectomy,17 underwent right hemihepatectomy + cholecystectomy,16 underwent cholecystectomy + hepatic left lateral lobectomy,11 underwent left hemihepatectomy + cholecystectomy,11 underwent duodenal papillary local excision+papilla reconstruction,11 underwent Roux-en-Y choledochojejunostomy anastomosis,4 underwent cholecystectomy + extrahepatic bile duct local excision + end-to-end bile duct anastomosis and 1 underwent endoscopic mucosal resection of duodenal papillary adenomna.Of 136 patients with postoperative complications,25 were complicated with pancreatic leakage,11 with bile leakage,2 with postoperative hemorrhage and 1 with hepatic failure.Two patients with pancreatic leakage died of massive hemorrhage caused by abdominal infection,1 died of hepatic failure and other patients were discharged from hospital after symptomatic treatment.(5) Follow-up situations:47 of 136 patients were followed up for 3-123 months,with a follow-up rate of 34.6％.During follow-up,2 patients undergoing duodenal papillary local excision + papilla reconstruction had canceration,and other patients had good survival.Conclusions There is a low clinical incidence of benign tumor of the bile ducts,which is more common in male than in female,and in adenomas (including cystadenoma) and papillomas.The preoperative imaging examinations or ERCP biopsy pathological examination can increase an accuracy of preoperative diagnosis.Benign tumors with high canceration rates need positive surgical treatment.

Objective To analyze the clinicopathological features and lymph node metastases characteristics of intrahepatic cholangiocarcinoma (ICC).Methods The retrospective case-control study was conducted.The clinicopathological data of 1 321 ICC patients who were admitted to 12 hospitals from April 2007 to November 2017 were collected,including 182 in the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University,173 in the First Affiliated Hospital of Xi'an Jiaotong University,156 in the First Hospital Affiliated to Army Medical University (Third Military Medical University),139 in the Cancer Center of Sun Yatsen University,128 in the Zhongshan Hospital of Fudan University,113 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine,109 in the First Affiliated Hospital of Dalian Medical University,84 in the Tianjin Medical University Cancer Institute and Hospital,65 in the First Affiliated Hospital of Zhengzhou University,62 in the Affiliated Hospital of North Sichuan Medical College,58 in the Affiliated Drum Tower Hospital of Nanjing University Medical School and 52 in the Second Affiliated Hospital of Zhejiang University School of Medicine.Treatment planning was respectively determined by comprehensive hospitals according to clinical features and results of related examinations.Surgical procedures were performed based on the results of intraoperative examinations and patients' conditions.Observation indicators:(1) laboratory examination and treatment situations;(2) relationship between clinicopathological features and primary tumor location and diameter;(3) diagnosis of lymph node dissection and metastases;(4) relationship between clinicopathological features and lymph node metastases.Measurement data with normal distribution were represented as x±s,and comparison between groups was done by the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the chi-square test.Results (1) Laboratory examination and treatment situations:of 1 321 patients,cases and percentages of positive hepatitis B virus (HBV),positive serum alpha-fetoprotein (AFP) (＞ 20 μg/L),positive serum carcinoembryonic antigen (CEA) (＞ 5 μg/L),positive serum alanine transaminase (ALT) (＞75 U/L),positive serum CA19-9 (＞37 U/mL) and positive serum total bilirubin (TBil) (＞20 μmol/L) were respectively 202,80,329,207,590,300 and 15.586％ (202/1 296),7.339％(80/1 090),26.299％ (329/1 251),16.587％ (207/1 248),49.789％(590/1 185),24.000％ (300/1 250).Of 1 321 patients,1 206 underwent surgery,including 904 with hepatectomy,193 with transcatheter arterial chemoembolization (TACE),72 with percutaneous transhepatic biliary drainage (PTBD),3 with endoscopic retrograde cholangiopancreatography (ERCP),3 with PTBD + ERCP and 31 with other treatments;115 had missing registration of surgical procedures.(2) Relationship between clinicopathological features and primary tumor location and diameter:① Relationship between clinicopathological features and primary tumor location:cases with CA19-9 level ≤ 37 U/mL,38-200 U/mL and ＞ 200 U/mL were respectively 227,91,146 with primary tumor located in left liver and 282,134,137 with primary tumor located in right liver.Cases combined with hepatitis and intrahepatic bile duct stone were respectively 67,73 with primary tumor in left liver and 111,47 with primary tumor in right liver,with statistically significant differences in above indictors (x2 =6.710,5.656,12.534,P＜0.05).The results of further analysis showed that incidence age of ICC was (63± 10)years old in patients with hepatitis and (59± 10) years old in patients without hepatitis,with statistically significant differences (t =4.840,P＜0.05).② Relationship between clinicopathological features and primary tumor diameter:cases with primary tumor diameter ≤ 3 cm,with 3 cm ＜ primary tumor diameter ≤ 5 cm and with primary tumor diameter ＞ 5 cm were respectively 159,250,229 with CEA level ≤ 5 pg/L and 40,65,95 with CEA level ＞ 5 μg/L and 165,258,286 with ALT level ≤ 75 U/L and 34,57,36 with ALT level ＞ 75 U/L and 148,242,281 with TBil level ≤ 20 μmol/L and 51,73,43 with TBil level ＞ 20 μmol/L,and 37,70 and 131 patients had satellite loci of tumor,with statistically significant differences in above indictors (x2=8.669,6.637,15.129,34.746,P＜0.05).(3) Diagnosis of lymph node dissection and metastases:of 904 patients with hepatectomy,346 received lymph node dissection,total number,number in each patient and median number of lymph node dissected were respectively 1 894.0,5.5 and 4.0 (range,1.0-26.0);157 had lymph node metastases,with a rate of lymph node metastasis of 45.376％ (157/346),number and number in each patient of positive lymph node were respectively 393.0 and 2.5.Of 346 patients with lymph node dissection,114 had lymph node metastasis by preoperative imaging examination,postoperative pathological examinations confirmed 64 with lymph node metastasis and 50 without lymph node metastasis;232 didn't have lymph node metastasis by preoperative imaging examination,postoperative pathological examinations confirmed 93 with lymph node metastasis and 139 without lymph node metastasis.The sensitivity,specificity and diagnostic accuracy by imaging examination were respectively 40.8％,73.5％ and 58.7％.(4) Relationship between clinicopathological characteristics and lymph node metastases:lymph node metastasis rate was respectively 51.397％ (92/179) in patients with primary tumor located in left liver,39.103％ (61/156) in patients with primary tumor located in right liver,34.615％(18/52) in patients with primary tumor diameter ≤ 3 cm,42.500％(51/120) in patients with 3 cm ＜ primary tumor diameter ≤ 5 cm,52.980％(80/151) in patients with primary tumor diameter ＞ 5 cm,48.790％(121/248) in patients with CEA ≤ 5 μg/L,59.302％ (51/86) in patients with CEA ＞ 5 μg/L,40.234％ (103/256) in patients with TBil ≤ 20 μmol/L,35.106％ (33/94) in patients with TBil ＞ 20 μmol/L,with statistically significant differences in above indictors (x2 =5.078,6.262,9.456,5.156,P ＜ 0.05).Conclusions The related etiological factors may be different due to different primary location of ICC.Primary tumor in left liver is significantly associated with intrahepatic bile duct stone of left liver,and primary tumor in right liver is associated with combined hepatitis,while combined hepatitis could lead early occurrence of ICC.At present,there is a low rate of lymph node dissection in ICC patients and a high lymph node metastasis rate in patients receiving lymph node dissection.Lymph node metastasis is associated with primary tumor location and diameter,levels of CEA and TBil.Lymph node metastasis rate in left liver is higher than that in right liver,and is getting higher with increased primary tumor diameter.
