Tea Drinking Customs in China

When you visit a Chinese home, you will be given a cup of hot tea irrespective of the geographical location, cultural background and nationality of the host. This is part of China’s ritual and culture. However, tea drinking customs vary in certain parts of China. Min-chao congou tea. Min-chao refers to the areas covering southern Fujian Province and Chaozhou and Santou in Guangdong Province. congou means the special skill of making tea.

Impact of mTOR gene polymorphisms and gene-tea interaction on susceptibility to tuberculosis

BACKGROUND mTOR gene is a key component of the PI3K/Akt/mTOR signaling pathway,and its dysregulation is associated with various diseases.Several studies have demonstrated that tea drinking is a protective factor against tuberculosis(TB).This study was designed to explore five single nucleotide polymorphisms(SNPs)of mTOR in the Han population of China to determine how their interactions with tea drinking affect susceptibility to TB.AIM To investigate if the polymorphisms of mTOR gene and the gene-tea interaction are associated with susceptibility to TB.METHODS In this case-control study,503 patients with TB and 494 healthy controls were enrolled by a stratified sampling method.The cases were newly registered TB patients from the county-level centers for disease control and prevention,and the healthy controls were permanent residents from Xin'ansi Community,Changsha city.Demographic data and environmental exposure information including tea drinking were obtained from the study participants.We genotyped five potentially functional SNP sites(rs2295080,rs2024627,rs1057079,rs12137958,and rs7525957)of mTOR gene and assessed their associations with the risk of TB using logistic regression analysis,and marginal structural linear odds models were used to estimate the gene-environment interactions.RESULTS The frequencies of four SNPs(rs2295080,rs2024627,rs1057079,and rs7525957)were found to be associated with susceptibility to TB(P<0.05).Genotypes GT(OR 1.334),GG(OR 2.224),and GT+GG(OR 1.403)at rs2295080;genotypes CT(OR 1.562)and CT+TT(OR 1.578)at rs2024627,genotypes CT(OR 1.597),CC(OR 2.858),and CT+CC(OR 1.682)at rs1057079;and genotypes CT(OR 1.559)and CT+CC(OR 1.568)at rs7525957 of mTOR gene were significantly more prevalent in TB patients than in healthy controls.The relative excess risk of interaction between the four SNPs(rs2295080,rs2024627,rs1057079,and rs7525957)of mTOR genes and tea drinking were found to be-1.5187(95%CI:-1.9826,-1.0547,P<0.05),-1.8270(95%CI:-2.3587,-1.2952,P<0.05),-2.3246(95%CI:-2.9417,-1.7076,P<0.05)and-0.4235(95%CI:-0.7756,-0.0714,P<0.05),respectively,which suggest negative interactions.CONCLUSION The polymorphisms of mTOR(rs2295080,rs2024627,rs1057079,and rs7525957)are associated with susceptibility to TB,and there is a negative interaction between each of the four SNPs and tea drinking.

An Introduction of the Vaporized Therapy with Tea Herb Drink for Relieving Agitation due to Pulmonary Encephalopathy

What methods would you choose apart from increasing sedatives for agitation in an advanced patient with hypercapnic encephalopathy due to AECOPD?This is a 94-year-old female who suffered from COPD for over 30 years,occurred with an accelerated episode of cough,productive sputum and a dropping down to 86%in SatO₂due to a cold weather.A diagnosis of pulmonary encephalopathy(PE)was made on the basis of the subsequent agitation and delirium,and the sedatives,such as quatiepine and haloperidol,had to be given for her mental excitation respectively,but she still pulled out indwelling needle herself and refused to any infusion therapy.As an alternative,a vaporized therapy integrated with tea herb drinking had to be applied to relieving her agitation,being designed as the vaporization of the inhaled oxygenation by means of high-flow oxygenation device(HFOD),with an ampoule of ambroxol mixed into the inhaler and simultaneous drinking of TCM tea herb for reducing sputum,helping dissolve the mucoid bolts inside her terminal bronchioles when being infected.We thought that a better efficacy would be achieved for hypercapnic encephalopathy due to AECOPD if we concentrate on a good ventilation of small airway through the vaporized therapy.

Association of CASP9,CASP10 gene polymorphisms and tea drinking with colorectal cancer risk in the Han Chinese population

The initiators caspase-9 （CASP9） and caspase-10 （CASPIO） are two key controllers of apoptosis and play important roles in carcinogenesis. This study aims to explore the association between CASPs gene polymorphisms and colorectal cancer （CRC） susceptibility in a population-based study. A two-stage designed population-based case-control study was carried out, including a testing set with 300 cases and 296 controls and a validation set with 206 cases and 845 controls. A total of eight tag selected single nucleotide polymorphisms （SNPs） in CASP9 and CASPIO were chosen based on HapMap and the National Center of Biotechnology Information （NCBI） datasets and genotyped by restriction fragment length polymorphism （RFLP） assay. Multivariate logistic regression models were applied to evaluate the association of SNPs with CRC risk. In the first stage, from eight tag SNPs, three polymorphisms rs4646077 （odds ratio （OR）AA＋AG： 0.654, 95% confidence interval （CI）： 0.406-1.055; P=0.082）, rs4233532 （ORcc： 1.667, 95% CI： 0.967-2.876; Oacm： 1.435, 95% CI： 0.998-2.063; P=0.077）, and rs2881930 （ORcc： 0.263, 95% CI： 0.095-0.728, P=0.036） showed possible association with CRC risk. However, none of the three SNPs, rs4646077 （ORAA＋AG： 1.233, 95% CI： 0.903-1.683）, rs4233532 （ORcc： 0.892, 95% CI： 0.640-1.243; ORcT： 1.134, 95% CI： 0.897-1.433）, and rs2881930 （ORcc： 1.096, 95% CI： 0.620-1.938; ORcT： 1.009, 95% CI： 0.801-1.271）, remained significant with CRC risk in the validation set, even after stratification for different tumor locations （colon or rectum）. In addition, never tea drinking was associated with a significantly increased risk of CRC in testing set together with validation set （OR： 1.755, 95% CI： 1.319-2.334）. Our results found that polymorphisms of CASP9 and CASPIO genes may not contribute to CRC risk in Chinese population and thereby the large-scale case-control studies might be in consideration. In addition, tea drinking was a protective factor for CRC.

Correlation between Thymidylate Synthase Genotype and Susceptibility to Gastric Carcinoma

OBJECTIVE To investigate the correlation between polymorphism of the 5′-untranslated region （5′-UTR） of thymidylate synthase genes, as well as the lifestyle, and the susceptibility of gastric carcinoma. METHODS A case-control study, with 60 cases of gastric carcinoma and 170 cases of general risk population-based controls from Nantong, Jiangsu province, China, was conducted. The epidemiological data, such as living habits of the cancer patients, were collected. DNA of peripheral blood leukocytes was obtained from all of the subjects. The TS 5′-UTR tandem repeat genotype was detected using polymerase chain reaction （PCR）. RESULTS There were three TS 5′-UTR genotypes in the group of gastric cancer cases （2R/2R, 2R/3R and 3R/3R） and six TS 5′-UTR genotypes in the group of the controls （2R/2R, 2R/3R, 3W3R, 2R/4R, 2R/5R and 3R/4R）. The genotypic frequencies were respectively 5.0%, 43.3% and 51.7% in the gastric cancer group. Compared with the parameters in the control group, i.e., 4.7%, 31.7%, 60.6%, 1.2%, 1.2% and 0.6%. There were no significant differences between the two groups. Compared with the 3R/3R- genotype individuals who where non-smokers, drank alcohol twice or less each week, drank tea and did not intake pickled food （PF）, the risk of gastric cancer significantly went up in the 2R/2R or 2R/3R-genotype people who had habits of smoking, drinking alcohol more than twice each week, no tea drinking but with frequent intake of PF. The adjusted ORs were as follows, 3.79 （95% CI： 2.45-8.64）, 3.41 （95% CI and 3.61 （95% CI： 1.81-8.78）. CONCLUSION There is 1.21-8.47）, 5.99 （95% Ch 3.01-14.7）, an obvious correlation between the polymorphisms of TS 5′-UTR genotypes and the lifestyle of individuals in the development of gastric carcinoma.

Chinese Tea Drinking Goes Back Centuries

TEA is a necessity in Chinese life. According to historical records the Chinese had already learned how to plant and bake tea more than 2,000 years ago. Sipping tea has always been a favorite Chinese tradition. To the south of the Changjiang River is a region with good irrigation and a climate favorable for growing tea: it is cool at night and often misty. Zhejiang Province is a well-known tea production area, and the famous Longjing Tea is solely produced along the West Lake in Hangzhou, capital of the province. Tea is produced in four areas of China:
