Objective To investigate the Huatan Huoxue Jiangqi prescription in treating AECOPD clinical curative effect. Methods 123 patients with AECOPD were randomly divided into the treatment group and the control group. The two groups were treated with western medicine, and the treatment group added with Chinese herbal medicine treatment with Huatan Huoxue Jiangqi prescription. The syndrome effect, clinical symptom score, CAT score, mMRC classification, lung function, the serum FIB and CRP levels were obtained to evaluate the efficacy of the two groups before and after treatment. Results The syndrome effect of the treatment group was significantly better than that of the control group. Compared with the control group, there was significant difference between traditional Chinese medicine syndrome score, CAT score (P < 0.05); Lung function (including FEV1, FEV1%, FEV1/FVC) was significantly improved in the treatment group after treatment (P < 0.05). The serum FIB and CRP levels decreased significantly in the treatment group compared with the control group (P < 0.05). Conclusion Huatan Huoxue Jiangqi prescription has reliable effets on treating AECOPD.

Due to the ongoing outbreak of COVID-19, we reflect on the optimization of teaching content and the guidance to deep learning, from the perspective of TCM teaching research. We believe that it's necessary to pay attention to the overall integration of TCM theories, academic researching, and clinical practicing when teaching. By excavating and sorting out the knowledge system of TCM, a clear conceptual pedigree of academic inheritance is constructed. In the teaching of traditional Chinese pharmacy, we should integrate the reconsideration and multi-dimensional research on the theory of medicinal properties, and make preparations for the development of Chinese medicine in a new direction through the cross-integration of various disciplines.

OBJECTIVETo describe trends of changes in blood lead levels in children aged 1 - 6 years during the time period before and after introducing lead free gasoline in Shanghai 1997 and 1999.

METHODSBlood lead levels of 1 969 children aged 1 - 6 years were determined by a sampling survey in five districts of Shanghai in August and September, 1997. Blood lead levels of the same population were re-determined by the same method from April to June in 1998 and from August to September in 1999. Filter paper blood lead test was carried out monthly using the filter paper blood lead proficiency testing program of Centers for Disease Control in the United States. The results from blood lead samples were under acceptable ranges during the study.

RESULTSThe geometric means of blood lead levels were 83 microgram/L in 1997, 80 microgram/L in 1998 and 76 microgram/L in 1999, respectively. The prevalence rates of childhood lead poisoning (blood lead level was equal or more than 100 microgram/L) were 37.8% in 1997, 25.7% in 1998 and 24.8% in 1999. The amounts of decrease on average blood lead levels in the five districts between 1997 and 1999 were 10 microgram/L, 11 microgram/L, 6 microgram/L, 4 microgram/L and 2 microgram/L, respectively.

CONCLUSIONLead poisoning is a preventable disease. The average levels of lead in young children in Shanghai decreased significantly after the introduction of lead free gasoline to Shanghai. Lead emissions from vehicles running on leaded gasoline was one of the important contributors to increase the children's blood lead levels in Shanghai. Lead poisoning is not evenly distributed among children in Shanghai, resulting in the different levels of decline.

Objective:To monitor the blood pressure in pediatric patients with coarctation of the aorta (CoA) before and 8 years after surgery, and explore the mechanism of elevated blood pressure in pediatric patients with repaired CoA.Methods:A cohort of 23 pediatric patients who underwent CoA repair between January 2010 and October 2010 in Guangzhou Women and Children's Medical Center was studied. And 20 age-, sex-match patients with isolated ventricular septal defect (VSD) who underwent surgery at the same time, 20 age-, sex-match health patients with normal echocardiographic findings were included in the study. Systolic blood pressure (SBP), diastolic blood pressure (DBP), arm-leg SBP gradient, right carotid intima-media thickness (CIMT), serum transforming growth factor-β1 (TGF-β1) were monitored at baseline(1 day before surgery) and 8-year follow-up (8 years after surgery).Results:There were no differences in SBP and DBP among patients with CoA, patients with VSD and health children at baseline ( P>0.05). But at 8-year follow-up, 2 patients with CoA exhibited hypertension. Not only that, patients with CoA had higher SBP than patients with VSD and health children at 8-year follow-up ( P<0.05). Patients with CoA had higher arm-leg SBP gradient than patients with VSD and health children at baseline ( P<0.01). But there were no differences in arm-leg SBP among patients with CoA, patients with VSD and health children at 8-year follow-up ( P>0.05). Patients with CoA had increased CIMT and higher serum levels of TGF-β1 at baseline and 8-year follow-up ( P<0.05). The preoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with their levels at 8-year follow-up, respectively ( P<0.01). There was a strong correlation between the levels of CIMT and serum TGF-β1 in patients with CoA, both preoperatively and postoperatively ( P<0.01). The preoperative and postoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with SBP at 8-year follow-up, respectively( P<0.05). Conclusion:Although surgery can successfully cure the anatomical " stenosis" , patients with CoA have elevated systolic blood pressure than normal people and patients with simple congenital heart disease (such as VSD). And some of the patients with CoA suffer from hypertension at long-term follow-up, even they are normotensive preoperatively. It may be related to vascular remodeling, in which TGF-β signaling pathway may be involved. Monitoring CIMT and TGF-β1 in patients with CoA preoperatively may be significative for prediction for the levels of SBP postoperatively.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

BACKGROUND: Derlin 3 (DERL3) is downregulated in colorectal cancer (CRC) samples. Its level is closely linked to lymphatic metastasis or distant metastasis rate in CRC patients. However, its biological behavior in lung adenocarcinoma were rarely reported. The aim of this study is to investigate the ectopic expression of DERL3 in lung adenocarcinoma tissues and its effect on the invasion and metastasis of lung adenocarcinoma A549 cell line to reveal the possible mechanism of invasion and metastasis of lung adenocarcinoma. METHODS: Lung adenocarcinoma microarray gene chip data included 3 cases of lymph node metastasis and 3 cases of lung adenocarcinoma tissue without lymph node metastasis. The GEDS and Kaplan-Meier plot queries the survival curve and expression level of DERL3. Western blot was used to detect the expression of DERL3 in lung adenocarcinoma cells. The efficiency of knockdown DERL3 gene was detected by Western blot assay. Transwell detected the number of cells passing through the basement membrane of the transwell. EDU assay detected cell proliferation ability. Western blot detected the expression of epithelial-mesenchymal transition related proteins E-cadherin and Vimentin. RESULTS: The microarray gene chip results showed that compared with lung adenocarcinoma tissues without lymph node metastasis, 1,314 mRNAs in lung adenocarcinoma tissues with lymph node metastasis were up-regulated, 400 mRNAs were down (P<0.05). The expression of DERL3 increased in lung adenocarcinoma (P<0.05). The results of survival curve showed that the lung cancer patients with high expression of DERL3 with poor prognosis (P<0.05). Western blot results indicated that plasmid transfection was successful. Knockdown of DERL3 suppressed the ability of proliferation, invasion and migration in A549 cells (P<0.05). After knockdown of DERL3, the expression level of Vimentin was decreased, while E-cadherin expression increased (P<0.05). CONCLUSIONS Knockdown of DERL3 inhibited the proliferation, invasion and metastasis of A549 cells.
