A total of 72 patients with first-episode mild-and-moderate depression took Qishen Fukang Capsules.The change of event-related potential P3 was determined before and after treatment for 6,12 and 24 weeks.And another 70 healthy controls received the same tests simultaneously.Compared with before treatment,HAMD scores after treatment were lower in the patient group [(29.1 ± 5.1) score vs.(10.4 ±4.1) score].P3 latencies were shorter and amplitudes became higher after treatment (P ＜0.01).And the difference of before and after treatment for 6 weeks was larger than the difference of 12 weeks and after treatment for 6 weeks (P ＜ 0.01).The curative effect is definite.And the clinical symptoms and brain evoked potential index have improved in patients with first-episode mild-and-moderate depression after medication.

OBJECTIVETo observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferon-γ (IFN-γ)/interleukin-4 (IL-4) in peripheral blood and disease activity in primary Sjogren's syndrome (pSS) patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity.

METHODSA total of 66 pSS patients were randomized with tossing coins method into two groups: the integrative therapy group (34 cases) and the control group (32 cases); and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G (IgG), erythrocyte sedimentation rate (ESR), IFN-γ and IL-4 in peripheral blood were measured before and after treatment.

RESULTSCompared with the normal group, the levels of IgG, ESR, IFN-γ and IL-4 were significantly increased in pSS patients (P<0.05). Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN-γ and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment (P<0.05). The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN-γ and the ratio of IFN-γ/IL-4 in the integrative therapy group were significantly lower than the control group (P<0.05). For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR.

CONCLUSIONChinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.

OBJECTIVETo explore the feasibility and effectiveness of worksite-based cardiovascular disease (CVD) prevention and control program in urban population of China.

METHODSWorksite-based intervention program was implemented 110 000 employees at Capital Iron and Steel Company of Beijing (CISC) focusing on primary prevention for CVD and control of hypertension. Intervention components comprised of infrastructure setting-up, health education and health promotion, professional training, detection and management of hypertensive patients, and reasonably readjusting their diet structure focusing on salt intake reduction, reducing their overweight, quitting smoking, and restricting alcohol consumption in high-risk population. Changes in level of risk factors, incidence and mortality of stroke and coronary events and their trend were evaluated between the intervention group at CISC and eight simultaneously parallel reference groups in other provinces outside Beijing with population surveillance data.

RESULTSMajor risk factors for CVD, including blood pressure, body mass index and serum cholesterol level, decreased relatively in intervention population at CISC during 1974 to 1998, while those in majority of eight parallel reference groups at different provinces of China significantly increased at the same time. Systolic blood pressure (SBP) decreased by 0.8 mm Hg and 4 mm Hg in average for men and women, respectively, and their diastolic blood pressure (DBP) remained the same as baseline for both men and women at CISC, while SBP increased by (2 - 11) mm Hg and (6 - 8) mm Hg in average for men and women, respectively in reference groups, and DBP increased by (2 - 6) mm Hg in average for men in five of eight reference groups, and by (3 - 6) mm Hg for women in four of eight reference groups. Serum level of cholesterol decreased by 0.26 mmol/L in women and slightly increased for men at CISC, and increased by (0.35 - 0.97) mmol/L for men and (0.29 - 1.05) mmol/L for women in all reference groups. Prevalence of overweight increased by 58.7% for men and 11.3% for women at CISC and increased by one to 22 folds in eight reference groups. Awareness of health knowledge improved significantly with an average net reduction of SBP/DBP of (2.5/2.2) mm Hg in the enforced intervention group at CISC than that in general intervention groups. Incidence and mortality rates of stroke decreased by 54.7% and 74.3%, respectively in intervention group at CSIC, but those of coronary events slowly increased with fluctuation.

CONCLUSIONWorksite-based comprehensive intervention for CVD prevention and control was feasible and cost-effective in decreasing risk factors for CVD, incidence and mortality rate of stroke in population of urban areas of China.

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

There are geographical, regional, and ethnic differences in the phenotypes and endotypes of patients with drug hypersensitivity reactions (DHRs) in different parts of the world. In Asia, aspects of drug hypersensitivity of regional importance include IgE-mediated allergies and T-cell-mediated reactions, including severe cutaneous adverse reactions (SCARs), to beta-lactam antibiotics, antituberculous drugs, nonsteroidal anti-inflammatory drugs (NSAIDs) and radiocontrast agents. Delabeling of low-risk penicillin allergy using direct oral provocation tests without skin tests have been found to be useful where the drug plausibility of the index reaction is low. Genetic risk associations of relevance to Asia include human leucocyte antigen (HLA)-B*1502 with carbamazepine SCAR, and HLA-B*5801 with allopurinol SCAR in some Asian ethnic groups. There remains a lack of safe and accurate diagnostic tests for antituberculous drug allergy, other than relatively high-risk desensitization regimes to first-line antituberculous therapy. NSAID hypersensitivity is common among both adults and children in Asia, with regional differences in phenotype especially among adults. Low dose aspirin desensitization is an important therapeutic modality in individuals with cross-reactive NSAID hypersensitivity and coronary artery disease following percutaneous coronary intervention. Skin testing allows patients with radiocontrast media hypersensitivity to confirm the suspected agent and test for alternatives, especially when contrasted scans are needed for future monitoring of disease relapse or progression, especially cancers.

Zha-xun is widely used in Tibetan medicine and is also an international traditional medicine. This article would summarize the use status and research progress of Zha-xun by various ethnic groups all over the world, and the results show that it has various synonyms but most of them imply its most characteristic feature-outflow from the rock; Zha-xun resources are distributed in various places of the world, and its bearing spots are closely related to the geological structure; there are sharp arguments on the origins of Zha-xun, mainly including the minerals origin, biological fossils origin, biological origin, etc. Zha-xun has multiple functions and is mainly used to treat stomach disease, liver disease and rheumatoid arthritis in China, and premature ejaculation, impotence, vaginitis embolism in foreign countries. "Iron" Zha-xun is used into medicines both at home and abroad. According to ancient materia medica texts, it was mainly classified into five types, including gold Zha-xun, silver Zha-xun, copper Zha-xun, iron Zha-xun and lead Zha-xun mainly based on the predominance of color rather than the minerals contained. It is commonly believed by the domestic and foreign scholars that humic acid is the main medicinal part of Zha-xun, and their studies have found that it has a variety of pharmacological activities such as anti-ulcer, anti-inflammatory, liver protection, analgesia, immune regulation, increasing sexual desire and fertility, antioxidation, antibacterial, antidiabetic, antiepileptic, antipsychotic, etc. This paper provides a scientific basis for the rational utilization of Zha-xun resources.

Zha-xun is widely used in Tibetan medicine and is also an international traditional medicine. This study believes that the black organic matter constituting Zha-xun is mainly stored in the rocks. The exudation points of Zha-xun mostly distribute on the cliffs of high mountains, which makes it difficult to evaluate its resource distribution and storage area. This paper was aimed at the exudation environment of Tibetan medicine Zha-xun in Sichuan province and 6 ecological environmental factors of the Zha-xun were determined via the field investigation. Combining with these 6 factors as well as the GIS data of Sichuan province, ArcGIS software was used to extract ideal environmental factors which are suitable for exudation of Zha-xun, including geology types, geomorphological types, altitude, slope, vegetation types, and mean annual temperature. The spatial overlay analyses on the extracted environmental factors were carried out to predict the distribution area of Zha-xun in Sichuan province. Afterwards, field investigation was conducted to verify the prediction. The prediction showed that the exudation spots of Zha-xun in Sichuan province mainly located in 29 counties including 12 in Aba Prefecture, 15 in Ganzi Prefecture, and Muli County and Dechang County in Liangshan Prefecture. The deposit areas of Zha-xun were located in the Triassic, Devonian and Silurian strata and were basically distributed in 9 basins, including Dingqu River, Yalong River, Xianshui River, Dadu River, Suomo River, Minjiang River and Baishui River, characterized by a fragmented patch-like distribution along the mountain ranges, and the exudation spots of Zha-xun were mainly scattered among the rain-free cliffs' concavities of river valleys at a certain altitude. The prediction was consistent with the field investigation results, which suggested that it is possible and feasible to predict distribution of Zha-xun resources based on GIS-analysis. The study may provide a scientific basis for comprehensive investigations into Zha-xun's distribution and formation mechanism, thus promoting rational development and utilization of Zha-xun resources.

Using beta-2 adrenergic receptor, 5-hydroxytryptamine and angiotensin II type 1 receptor as control, we here established a method for rapid prediction of the initial position amino acids of N-terminal, C-terminal, intracellular loops, extracellular loops and transmembrane (TM) regions in G protein-coupled receptors (GPCRs), and successfully predicted the structure of Mas-related G protein-coupled receptors X3 (MRGPRX3). To achieve this purpose, nanoluciferase (Nluc) was inserted into the different sites of these GPCRs′ sequence by sequence and ligation-independent cloning (SLIC) method, and the luminescence value were measured to distinguish the different parts of GPCRs. The results showed that luminescence values of NLuc luciferase at TM region were less than 100 000, and the values were higher than 1 000 000 at N terminal, C terminal, or extracellular loops and intracellular loops, and the values were between 100 000 and 500 000 at junction. The predicted MRGPRX3 structure was analyzed in detail and was compared with AlphaFold predicted structure. In conclusion, this method could provide useful information of GPCR structure model for the ligand virtual screening, and could provide certain experimental basis for structural pharmacology.
