Objective To investigate the curative effect of modified Yanghe decoction on pulmonary interstitial fibrosis.Methods In this study,62 patients suffering fiom pulmonary interstitial fibrosis were randomly divided into 2 groups with the use of the Random Number Table method.31 cases in the treatment group were treated with modified Yanghe decoction,while 31 cases in the control group were treated with prednisone,40 mg/d (produced by Zhejiang Xianju Pharmaceutical Factory).The dosages of prednisone were gradually reduced a month later.The changes and improvement in symptoms,pulmonary function,chest CT,etc were observed and analyzed after three month.Results The study showed that the total?effective?rates of the treatment group and control group were 83.9％ (26/31) and 58.1％ (18/31) respectively,and the difference had statistical significance (P=0.031,P＜0.05).The integrals of gasping,breathlessness,cough and Velcros Rale of the treatment group before the treatment were (3.1 ± 2.61),(4.1 ± 1.53),(1.38 ± 1.02),(1.56 ±2.34)respectively while those of the control group were (2.83±2.34),(3.90±1.67),(1.28±1.24),(1.61±2.14) respectively.The after-treatment integrals of the treatment group were (1.1 ± 1.06),(1.52± 1.40),(0.36±0.71),(0.65±0.67)respectively while those of the control group were(1.2± 1.33),(2.15±1.31),(0.41±0.70),(0.78 ± 0.30)respectively.Compwered with their symptoms before the treatment,there was obviousimprovement in the symptoms of both groups after the treatment,(P＜0.05),but the difference in these aspects between the two groups had no statistical significance (P＞0.05).Before the treatment,the total lung capacity,vital capacity,diffusion function,arterial oxygen pressure of the treatment group were (69.80±21.7) ％,(73.16±16.38) ％,(51.46± 16.42) ％,(69.70± 10.74) mm Hg (1 mm Hg=0.133 kPa) respectively while those of the control group were(77.52 ± 15.96)％,(74.57 ± 20.73)％,(55.68 ± 17.27)％,(64.86 ± 11.40)mm Hg respectively.After the treatment,the total lung capacity,vital capacity,mass function,arterial oxygen pressure of the treatment group were (82.31±21.65)％,(83.66±17.32)％,(62.34±17.96)％,(83.51±9.37)mm Hg respectively while those of the control group were (85.06± 16.10) ％,(85.72± 20.40) ％,(68.32± 20.16) ％,(79.61 ±9.41)mm Hg respectively.Compwered with their symptoms before the treatment,there was obvious improvement in the symptoms of both groups after the treatment (P＜0.05),but the difference in these aspects between the two groups had no statistical significance (P＞0.05).Conclusion Modified Yanghe decoction can be effectively applied in the prevention and treatment of pulmonary interstitial fibrosis.

Objective This study aimed to investigate the characteristics of maternal death cases, the cause of maternal death and the cause of medical dispute,and recommended the relative prevention measures. Methods We retrospectively analyzed 35 cases of maternal death identified in the College of Forensic Medicine in Kunming Medical University from January 2002 to December 2012. Results In 35 maternal death cases: (1) Most maternal deaths are over 30 years old (14 cases, 40%), followed by 17 to 19 years old (6 cases, 17.1%) . And most maternal deaths came from countryside (25 cases,71.4%) . (2) 26 cases maternal deaths happened during the perinatal period (68.5%) . (3) 26 cases happened in county hospitals, township hospitals and informal medical organizations (74.3%) . 5 maternal deaths happened on the way to the hospital or at home (14.3%) . (4) 17 cases died of obstetric hemorrhagic shock (48.6%), 11 cases died of amniotic fluid embolism (31.4%), 2 cases died of amniotic fluid embolism and obstetric hemorrhagic shock (5.7%) . (5) 30 cases of medical disputes were caused by maternal death. Among them, the clinical diagnosis was not consistent with the pathological diagnosis in 20 cases (The misdiagnosis rate was 66.7%) . (6) The causes of medical dispute:clinical diagnosis was unknown in 11 cases (36.7%),11 cases were suspected that rescue was not timely or improper (36.7%),and 8 cases were suspected of misdiagnosis (26.6%) . Conclusion Obstetric hemorrhage and pulmonary amniotic fluid embolism were the main reasons of the maternal death. The incidence of maternal death and medical disputes could be reduced by improving the ability of obstetric staff,and strengthening the diagnosis and treatment about obstetric hemorrhage and pulmonary amniotic fluid embolism. At the same time, women should improve their self-care awareness, reduce early marriage and early pregnancy,and enhance the consciousness of hospital treat and cure.

Objective:To explore the association of the total gestational weight gain (GWG) and GWG in different trimesters with adverse pregnancy outcomes during the second pregnancy in women with history of gestational diabetes mellitus (GDM).Methods:This retrospective cohort study recruited 441 singleton pregnant women with a history of GDM who gave birth at Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2017 to December 2018 as the GDM history group. Another 1 637 singleton pregnant women without a history of GDM who gave birth at the same period were selected through the mechanical sampling method as the control group. Independent sample t-test and Chi-square test were used to compare the differences in general conditions, GWG and perinatal outcomes between the two groups. Based on the Institute of Medicine guidelines for GWG, the subjects were further divided into three subgroups: inadequate GWG, adequate GWG and excessive GWG groups. Multivariate logistic regression analysis was used to compare the pregnancy outcome in women with the same GWG in different periods of pregnancy between the two groups. Results:(1) Women with GDM history had lower GWG before and after oral glucose tolerance test (OGTT) and the whole pregnancy than those without [(6.3±3.3) vs (7.9±3.7) kg, (4.8±2.6) vs (5.6± 2.6) kg, (11.8±4.6) vs (14.4± 4.6) kg; t=8.074, 5.183, 10.277; all P<0.001]. The incidence of GDM, gestational hypertension, and large for gestational age (LGA) in the GDM history group were higher than those in the control group [46.5% (205/441) vs 18.1% (296/1 637), 8.4% (37/441) vs 5.4% (88/1 637), 12.9% (57/441) vs 9.7% (158/1 637); χ2=153.181, 5.583, 4.013; all P<0.05]. (2) Before OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 4.02 (2.35-6.88), 3.92 (2.65-5.79) and 3.33 (2.11-5.25), respectively, all P<0.001]. Except for women with inadequate GWG, pregnancy with a history of GDM also had a higher risk of preeclampsia [ OR and 95% CI were 3.62 (1.47-9.23) and 2.22 (1.07-5.57) for adequate and excessive GWG, respectively, both P<0.05]. After OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 2.48 (1.60-3.84), 4.63 (2.92-7.35) and 4.22 (2.73-6.51), respectively, all P<0.001]. Pregnant women with a history of GDM with excessive GWG had an increased risk of preeclampsia ( OR=2.46, 95% CI: 1.10-5.51, P<0.05). During pregnancy: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI were 3.02(2.00-4.59), 4.08(2.76-6.04) and 2.66(1.54-4.59) for inadequate, adequate and excessive GWG, respectively, all P<0.001]. Women with GDM history had an increased risk of large for gestational age (LGA) in those with inadequate GWG and postpartum hemorrhage in those with excessive GWG [ OR and 95% CI were 1.94 (1.09-4.21) and 2.93 (1.31-6.55), respectively, both P<0.05]. Conclusions:The total GWG and GWG in different periods during the second pregnancy in women with a history of GDM are lower than those without, but with a higher risk of adverse outcomes. Even in women with the same range of GWG, GDM history still increases the risk of adverse pregnancy outcomes.

Objective: To explore a single center large cohort of patients with Takayasu’s arteritis for their clinical manifestation and long-term outcome in China. Methods: We retrospectively analyzed 566 patients with Takayasu’s arteritis admitted in our hospital from 2002-01 to 2013-11 for their clinical characteristics, laboratory ifndings, angiographic features, treatment and long-term outcomes. Results: The patient’s ratio for female to male gender was 1 to 3.8 and the average onset age was (28.9 ± 12.0) years. The most common non-speciifc symptom, initial symptom and complication were fever (52/566 patients, 9.2%), dizziness (214 patients, 37.8%) and hypertension (392 patients, 69.3%) respectively. The patients with pulmonary artery and coronary artery involvement were 83 (14.7%) and 66 (11.7%) respectively, and 131 (23.1%) patients had faster erythrocyte sedimentation rate. The major vascular damage was steno-occlusive lesion and the most common involvement was left sub-clavian artery, which was observed in 278 (49.1%) patients. The treatments were mainly included in medication, interventional therapy, autologous blood vessel transplantation, artiifcial blood vessel transplantation and aortic valve replacement. There were 32 patients died during the mean follow-up period of (5.0 ± 0.2) years. Hypertension, complication and the progressive stage of disease were the major factors affecting prognosis in relevant patients (regression coefifcients: 4.664, 1.959 and 1.870 respectively, allP<0.05). Conclusion: Hypertension was the leading reason for patients’ hospital visit. Takayasu’s arteritis was closely related to cardiovascular disease, the early diagnosis and treatment were really important in clinical practice.

Objective: To explore the clinical features and prognosis in patients with Takayasu arteritis (TA) combining neurological symptoms. Methods: We retrospectively studied 274 TA patients combining neurological symptoms who admitted to our hospital from 2002-01 to 2013-10 for their clinical and imaging features with prognosis. Results: The ratio of male to female was 1:4.3 and the mean age of disease onset was at (28.2±11.2) years. The most common neurological symptom was dizziness (214/274 cases, 78.1%), most frequent type was type III TA (112 cases, 40.9%), most common affected artery was left subclavian artery (147 cases, 53.6%), and there were 77 cases (28.1%) with (3-4) branches of the aortic arch involvement. For stroke conditions, ischemic stroke was more frequently observed in patients with steno-occlusive lesions in subclavian artery and common carotid artery, while hemorrhagic stroke was more frequently found in patients with steno-occlusive lesions in descending aorta, abdominal aorta and/or renal artery. Heart failure was the most common cause of death, it was also the most common cardiovascular event in surviving cohorts. Conclusion: TA patients could have many neurological symptoms, which were related to the number and site of artery involvement.

The aim of this study is to evaluate the effectiveness of a smart non-invasive blood glucose monitor prototype during pregnancy through clinical validation.The monitor utilizes near-infrared spectroscopy combined with AI big data analysis of photoelectric volumetric pulse wave data to achieve non-invasive monitoring of blood glucose in women during pregnancy.The research team developed a monitor that employs a sensing chip,effectively overcoming the problems of weak signals and individual differences in non-invasive blood glucose monitoring.The user experience is enhanced by visualizing the test results on the accompanying cell phone APP(application)of the smart non-invasive pregnancy blood glucose monitor.Clinical validation revealed that the non-invasive monitoring data for pregnant women aged 20～30 years significantly differed from those obtained via traditional blood glucose measurement methods,whereas no significant difference(P<0.05)was observed for pregnant women aged 31～42 years.The study concluded that further calibration of the monitor and an expansion of the sample size are necessary to enhance consistency with invasive glucose monitoring results.

Objective:To visualize and analyze the literature related to the treatment of extremity lymphedema (EL) over the years 2012 to 2022 and to explore future research directions.Methods:Taking "lymphedema" and "treatment" as the themes, the study searched the Chinese and English literature related to EL treatment reported by Chinese scholars from 2012 to 2022 in Chinese National Knowledge Infrastructure (CNKI) and Web of Science (WOS) databases, and used CiteSpace software to visualize the literature, draw maps of authors, research institutes, keywords, etc., and carry out clustering and emergent word analysis on the keywords.Results:A total of 1 007 Chinese articles with 16 core authors and 236 English articles with 8 core Chinese authors were included. The author with the largest number of publications in Chinese was Liu Ningfei from the Ninth People’s Hospital of Shanghai Jiao Tong University School of Medicine (16 articles), and the author with the largest number of publications in WOS was Cheng Ming-Huei from Chang Gung Memorial Hospital Lin Kou Campus (Taiwan Province of China) (33 articles). The institution with the largest number of articles in Chinese was Sun Yat-sen University Cancer Center (16 articles), and the institution with the largest number of articles in English was Chang Gung University (Taiwan Province of China) (45 articles). "Breast cancer" "nursing care" and "quality of life" were the top 3 keywords in CNKI ; "breast cancer" "diagnosis" and "lower extremity" were the top 3 keywords in WOS. Cluster analysis of the keywords showed that 16 clusters in CNKI and 11 clusters in WOS covering evaluation indexes, treatment method and mechanism studies. The result of CNKI keyword emergence analysis showed that the top 10 emergent keywords were "postoperative breast cancer" "upper limb" "rehabilitation" "nursing care" "rehabilitation therapy" "intramuscular effect patch" "acupuncture therapy" "cervical cancer" "upper limb function" "lymphatic drainage". The result of WOS keyword emergence analysis showed that the top 10 emergent keywords were "prevalence" "extremity lymphedema" "therapy" "postmastectomy lymphedema" "transplantation" "cancer" "flap transfer" "mechanism" "surgical treatment" "reconstruction" .Conclusion:Surgical treatment, preventive nursing and lymphangiogenesis are the key research directions of EL treatment. Both traditional Chinese medicine and Western medicine have their own advantages in the treatment of EL, and the combination of traditional Chinese medicine and Western medicine can play a better role in the treatment. Multidisciplinary team can develop personalized solutions for patients.

We purified a novel mannose binding lectin form Musca domestica pupae by affinity chromatography on Con A-Sepharose 4B and DEAE weak anion-exchange chromatography. By SDS-PAGE, MBL-1 yielded a single band with the molecular weight of 24 kDa. It was a glycoprotein detected by periodic acid-schiffs staining reaction, with 97.36% protein and 2.1% oligosaccharide. Meanwhile, the results of beta-elimination reaction, infrared spectroscopy, atomic force microscopy and protein sequencing instrument show that MBL-1 was an ellipsoidal-shaped monomer with 60-100 nm in diameter. N-glycoside bond linked oligosaccharide chain and the N-terminal blocked peptide chain. Further study suggested that MBL-1 promote the proliferation of macrophage in a concentration-dependent manner. The scanning electron microscope analysis shows that MBL-1 promoted the activation of macrophages. These results show that MBL-1 purified from Musca domestica pupae possesses immune regulation effect, serving a reference basis to develop natural immune-modulator.
