Abstract
OBJECTIVES The aim of this study was to examine the disease burden of lung cancer attributable to particulate matter (PM2.5) pollution in China from 1990 to 2019. STUDY DESIGN Data from the Global Burden of Disease Study 2019 were used to estimate the disease burden of tracheal, bronchus and lung cancer attributed to PM2.5 over time in China. METHODS Joinpoint regression models were applied to disability-adjusted life years (DALYs) to assess the time trends and estimate the impact of PM2.5 on the overall disease burden of lung cancer. Furthermore, age-period-cohort models were conducted to assess the relationships between lung cancer DALYs attributed to PM2.5 exposure and age, calendar period and birth cohort trends in China from 1990 to 2019. RESULTS Lung cancer DALYs attributable to household air pollution from solid fuels decreased with an average annual percent change (AAPC) of 2.9 % per 100,000 population, while those attributable to ambient particular matter pollution (APE) increased (AAPC: -4.7 % per 100,000 population) over the past 30 years. The burden of lung cancer in terms of DALYs in males was higher than in females, and it demonstrated an age-dependent increase. The period and cohort effects also had significant impacts on the DALYs rates of lung cancer attributable to APE, indicating an overall increase in lung cancer DALYs for all age groups in each year. CONCLUSIONS This study highlights the need for effective strategies to reduce PM2.5 exposure in China, particularly from outdoor sources. Gender differences and age, period and cohort effects observed in the study provide valuable insights into long-term trends of lung cancer burden attributed to PM2.5.

Abstract
Chinese materia medica decoction pieces (CMMDPs), one of the three pillars of the Chinese materia medica industry, are a key link in the Chinese materia medica industrial chain. Industrialization is the only way for the modernization of CMMDPs. This review mainly summarizes the characteristics, history, current situation and prospect of CMMDPs industry, providing a new reference for promoting the flourishing development of the industrialization of CMMDPs and for serving massive health industry. The literature was collected from databases including Web of Science, PubMed, Elsevier and CNKI (Chinese). CMMDPs industry has the characteristics of regionalism, resource dependency, customer diversity and low industrial concentration. Deeply processed products include traditional Chinese medicine (TCM) formula granules, small-packed decoction pieces, ultrafine decoction pieces, puffed decoction pieces, compressed decoction pieces and instant decoction pieces. Integration of treatment and processing at the place of origin is emerging. However, there is still room for improvement, for example, the manufacturing technologies of CMMDPs industry need to be continually improved. The management of CMMDPs' normalized production also needs to be strengthened. The quality of CMMDPs should be strengthened supervision and it should establish the objective and feasible quality evaluation system for CMMDPs. At present, China has attached unprecedented importance to the development of TCM, and issued a number of supporting policies, sparing no effort to support its development.

Abstract
Abstract
Study question
For X-autosome translocation [t(X-A)] carriers, is it a more applicable preimplantation genetic testing (PGT) strategy, that distinguishing noncarrier from euploid/ balanced embryos and prioritized transfer?
Summary answer
Noncarrier and carrier embryos discrimination in PGT is an applicable strategy to avoid transferring genetic and reproductive risks to the offspring of t(X-A) carriers.
What is known already
Balanced t(X-A) is a specific reciprocal translocation, with a higher risk of detrimental phenotype and fertility issues compared to individuals with autosomal translocation. Alternative X-chromosome inactivation (XCI) is a specific pathogenic mechanism in this population. For carrier offspring of couples with t(X-A), the genetic counseling is challenged in both the prenatal and postpartum stages, because of the complexity and severity of phenotype outcomes that are unpredictable and associated with the complex XCI mechanism. Therefore, caution is necessary when designing a PGT strategy for couples with t(X-A).
Study design, size, duration
A retrospective study. We collected a 3-year-old girl with maternal translocation 46,X,t(X;1)(q28;p31.1) presenting with multiple congenital disabilities. Three couples with female t(X-A) carrier requesting for PGT.
Participants/materials, setting, methods
Karyotype analysis, whole-exome sequencing (WES), and X inactivation analysis were performed for the girl with congenital cardiac anomaly, language defect, and mild neurodevelopmental delay. PGT based on next-generation sequencing following the microdissecting junction region to distinguish noncarrier and carrier embryos were used in three couples with female t(X-A) carrier (Cases 1–3).
Main results and the role of chance
The girl carried a maternal balanced translocation 46,X,t(X;1)(q28;p31.1). WES revealed none monogenic mutation related to her phenotype, but she carried a rare skewed inactivation of the translocation X chromosome and spread to the adjacent interstitial 1p segment, contrary to her mother. All translocation breakpoints of Cases 1–3 were successfully identified and each couple underwent one PGT cycle. Thirty oocytes were retrieved, and 13 blastocysts were eligible for biopsy, of which 6 (46.15%) embryos were balanced and only 4 were noncarriers. Three frozen embryo transfers with noncarrier embryos resulted in the birth of two healthy children (one girl and one boy), who were subsequently confirmed to have normal karyotypes. We reported a girl with multiple congenital disabilities resulting from maternally balanced t(X-A) and validated that noncarrier and carrier embryo discrimination is an effective and applicable strategy for avoiding transferring genetic and reproductive risks to the offspring from t(X-A) carriers.
Limitations, reasons for caution
Here, we reported a girl with multiple congenital disabilities resulting from maternally balanced t(X-A) found different XCI patterns, while we did not further determine the mechanism causing the different XCI patterns between the girl and her mother.
Wider implications of the findings: We demonstrated passing on a balanced t(X-A) may result in clinical manifestations associated with the X-inactivation, and verified the PGT strategy, that distinguishing normal and carrier embryos in can widely applied in t(X-A) carrier couples to avoid the genetic and reproductive risk of transferring t(X-A) to the next generation.

Abstract
ATP (Adenosine triphosphate) is an important endogenous damage - associated molecular pattern (DAMP). P2X7R is an ATP-gated cation channel. ATP-P2X7R plays a vital role in the pathophysiology of many diseases because P2X7R is distributed on various immune cells. ATP-P2X7R signal transduction pathway has been implicated to participate in the body's immune defense against pathogens. This paper reviews the recent progress regarding ATP-P2X7R and its effects on parasitic diseases.

Abstract
BACKGROUND AND PURPOSE To test a hypothesis that: (i) duodenal pH and osmolarity are individually controlled at constant set points by negative feedback control centred in the enteric nervous system (ENS); (ii) the purinergic P2Y(1) receptor subtype is expressed by non-cholinergic secretomotor/vasodilator neurons, which represent the final common excitatory pathway from the ENS to the bicarbonate secretory glands. EXPERIMENTAL APPROACH Ussing chamber and pH-stat methods investigated involvement of the P2Y(1) receptor in neurogenic stimulation of mucosal bicarbonate (HCO(3)(-)) secretion in guinea pig duodenum. KEY RESULTS ATP increased HCO(3)(-) secretion with an EC(50) of 160 nM. MRS2179, a selective P2Y(1) purinergic receptor antagonist, suppressed ATP-evoked HCO(3)(-) secretion by 47% and Cl(-) secretion by 63%. Enteric neuronal blockade by tetrodotoxin or exposure to a selective vasoactive intestinal peptide (VIP, VPAC(1)) receptor antagonist suppressed ATP-evoked HCO(3)(-) secretion by 61 and 41%, respectively, and Cl- by 97 and 70% respectively. Pretreatment with the muscarinic antagonist, scopolamine did not alter ATP-evoked HCO3(-) or Cl(-) secretion. CONCLUSION AND IMPLICATIONS Whereas acid directly stimulates the mucosa to release ATP and stimulate HCO(3)(-) secretion in a cytoprotective manner, neurogenically evoked HCO(3)(-) secretion accounts for feedback control of optimal luminal pH for digestion. ATP stimulates duodenal HCO(3)(-) secretion through an excitatory action at purinergic P2Y(1) receptors on neurons in the submucosal division of the ENS. Stimulation of the VIPergic non-cholinergic secretomotor/vasodilator neurons, which are one of three classes of secretomotor neurons, accounts for most, if not all, of the neurogenic secretory response evoked by ATP.

Abstract
BACKGROUND AND PURPOSE To investigate whether brain iron deposition correlates with motor phenotypic expressions of Parkinson's disease. METHODS We subtyped patients with Parkinson's disease according to their main motor symptoms (tremor, rigidity/bradykinesia) into three subgroups: tremor-dominant subgroup, akinetic/rigid-dominant subgroup, or mixed subgroup. The iron levels in bilateral substantia nigra, globus pallidus, putamen, the head of caudate, and red nucleus of 87 patients and 50 control subjects were assayed by measuring phase values using susceptibility-weighted phase imaging in a 3-tesla magnetic resonance system. The serum ceruloplasmin levels of all subjects were determined. RESULTS The bilateral average phase values of the substantia nigra and all other brain regions examined did not correlate with the main motor symptoms of Parkinson's disease in the total patient group or when patients were grouped according to serum ceruloplasmin levels. Significant correlations between serum ceruloplasmin levels and nigral bilateral average phase values were observed in the tremor and akinetic/rigid-dominant subgroups. Analysis of patients without prior dopaminergic medication exhibited similar results. Increased nigral iron content correlated with disease severity as assayed by the Unified Parkinson's Disease Rating Scale motor scores in the PD(AR) subgroup. CONCLUSIONS These findings suggest that nigral iron deposition, correlating with decreased serum ceruloplasmin levels, is a risk factor in Parkinson's disease across multiple motor phenotypic expressions.

Abstract
Endothelin antagonists, novel tripeptides containing a series of unnatural amino acids, were synthesized and characterized. A linear peptide BQ-485, perhydroazepin-1-yl-L-leucyl (1)-D-tryptophanyl (2)-D-tryptophan (3), was selected as the parent compound. The introduction of D-Phe derivatives into these peptidic ET antagonists resulted in potent activity against the contraction of rat aortic smooth muscles induced by ET-1 (10 nM) which activated the ET receptors. Among these compounds, 15 tripeptides had high enough antagonistic activity at the level of 10(-7) mol/L (IC50). The activity of three compounds was 10(-6) mol/L (IC50). These HIM-CO-Leu-D-Trp-D-Phe(-R)-OH compounds as ETA antagonists may provide a tool for the development of therapeutic agents in the treatment of putative ET-1-related disorders.

Abstract
PTEN is a candidate tumour suppressor gene and frequently mutated in multiple cancers, however, not in pancreatic cancer. Recently, it has been demonstrated that PTEN expression is regulated by TGF-beta1. Using TGF-beta1 transgenic mice (n=7) and wildtype littermates (n=6), as well as pancreatic tissues obtained from organ donors (n=10) and patients with pancreatic cancer (n=10), we assessed the expression of PTEN by means of immunohistochemistry and semiquantitative PCR analysis. In addition, PANC-1 cells were treated with TGF-beta1 in vitro and the levels of PTEN mRNA were determined in these cells. In human pancreatic cancers PTEN mRNA levels were significantly decreased (P<0.05). In addition, in the pancreas of TGF-beta1 transgenic mice the expression of PTEN was significantly reduced (P<0.01), as compared to wildtype littermates and incubation of PANC-1 cells with TGF-beta1 decreased PTEN mRNA levels after 24 h. Inasmuch as TGF-beta1 decreases PTEN expression in human pancreatic cancer cells and human pancreatic cancers overexpress TGF-beta1, the reduced expression of PTEN in pancreatic cancer may be mediated by TGF-beta1 overexpression. Thus, although PTEN is not mutated in pancreatic cancers, the reduction of its expression may give pancreatic cancer cells an additional growth advantage.

Abstract
The exact role of apoptosis that occurs in human placenta during the early stage of pregnancy remains unknown because of the difficulty in obtaining the intact implantation site. In this study, we used rhesus monkey as an animal model to examine apoptosis occurring in the implantation site at various stages of early pregnancy. It was shown that Fas and FasL mRNA and protein were localized in both the chorionic villi and glandular epithelium from day 15 to day 30 of pregnancy. Fas and FasL protein were also expressed in the epithelial plaque on day 15 of pregnancy. In situ 3'-end-labeling results showed that glandular epithelial cells underwent extensive apoptosis with obvious morphological degradation during the early stage of pregnancy. It was found that the cells that were 3'-end-labeled in the chorionic villi and anchoring villi were mainly localized in cytotrophoblast and cytotrophoblast column. It is therefore suggested that in primates apoptosis, which may be involved in the regulation of proliferation of trophoblast villi and degradation of epithelial plaque, as well as remodeling of the glands in the maternal decidua, may play an important role during the early stage of implantation and placentation.

Abstract
PURPOSE Cyclins play a key role in the control and regulation of the cell cycle. The role of cyclins in the pathogenesis of pancreatic cancer is largely unknown. METHODS Using Northern blot analysis, polymerase chain reaction (PCR) and immunohistochemistry, we examined the expression of cyclins D1, D2, and D3 in human pancreatic cancer and studied the induction of these cyclins by growth factors in pancreatic cancer cell lines. RESULTS We now report that cyclin D1 and D3 mRNAs are expressed in human pancreatic cancer cell lines, and that the expression of cyclin D3 is enhanced in pancreatic cancer cells by amphiregulin, a member of the epidermal growth factor family. Cyclins D1 and D3 are also expressed in normal and malignant pancreatic tissues. However, while the normal pancreas and pancreatic cancers express cyclin D2 as determined by reverse-transcriptase PCR, we could not detect cyclin D2 mRNA by either Northern blot analysis or reverse transcriptase PCR in the two pancreatic cancer cell lines. Immunohistochemical analysis revealed the expression of cyclin D3 in pancreatic cancer cells. CONCLUSIONS These findings suggest that D-type cyclins are differentially expressed in pancreatic cancer and that the aberrant activation of the EGF receptor in human pancreatic cancer by amphiregulin may lead to the progression of the cell cycle via induction of cyclin D3 expression, thus contributing to the growth advantage of these transformed cells.

Abstract
Transforming growth factors beta (TGF-beta) constitute a family of polypeptide growth factors that control cell growth, cell differentiation and migration, as well as the formation of the extracellular matrix. Recent analyses revealed the overexpression of TGF-beta1 in human gastric cancers and demonstrated increased cell proliferation in the stomach of patients with gastric cancer and their first-degree relatives. Using human gastric tissues obtained from patients with gastric cancer (n = 19), biopsies from healthy first-degree relatives of gastric cancer patients (n = 18) and healthy individuals (n = 19), we analysed the expression of TGF-beta1 using the reverse transcriptase polymerase chain reaction (RT-PCR) and immunohistochemistry. Fifteen of 19 patients with gastric cancer expressed TGF-beta1 in the tumour. In 11 of these 15 cases TGF-beta1 mRNA was also detectable in the non-tumourous stomach. Interestingly, all but two individuals with a first-degree relative diagnosed with gastric cancer exhibited TGF-beta1 expression in either the antrum or corpus biopsy or both. In contrast, only one of 19 individuals without a family history of gastric cancer expressed TGF-beta1 in the stomach (P< 0.0001). TGF-beta1 expression is detectable in a large proportion of gastric cancers and in the stomach of healthy first-degree relatives of gastric cancer patients. Since individuals without gastric cancers in their family express TGF-beta1 only in one of 19 cases, the induction of TGF-beta1 expression in first-degree relatives of patients with gastric cancer points to the presence of specific molecular alterations in a subgroup of individuals with an increased risk of developing gastric cancer that may precede the development of gastric cancers.

Abstract
The capacity of the nucleocapsid protein of HBV to function as a T-cell independent antigen in man was studied. When T-cell depleted B-cell cultures were challenged with E coli-derived HBcAg, anti-HBc production was registered in culture supernatants from the majority of chronic HBsAg carriers in a quiescent stage of disease. In contrast, similarly prepared and stimulated cultures from donors with natural acquired immunity to hepatitis B or HB-susceptible controls were non-responsive. Addition of autologous T-cells effectively restored anti-HBc responsiveness in T-cell depleted B-cell cultures from HB-immune donors, demonstrating the T-cell dependency for anti-HBc induction in natural HBV-infection.
