RESUMEN
OBJECTIVE To investigate the effects of CYP3A5 gene polymorphism and Wuzhi capsule （WZ） on early postoperative tacrolimus exposure and adverse reactions in renal transplant patients. METHODS A total of 132 patients who underwent renal transplantation and received tacrolimus + mycophenolic acids + prednisone after operation in our hospital from September 2021 to September 2023 were selected and divided into four groups according to genotypes （CYP3A5*1 or CYP3A5*3/*3） and with or without WZ （“ +WZ” meant drug combination， “ +NO WZ” meant without combination）. The blood trough concentration/daily dose （c0/D） values of the four groups were analyzed on the 14th day， 1 month and 3 months after renal transplantation. The incidence of acute rejection and the incidence of tacrolimus-related adverse reactions within 3 months after transplantation were compared among 4 groups. RESULTS On the 14th day， 1 month and 3 months after surgery （except for the CYP3A5*1+WZ group）， c0/D values of CYP3A5*1 genotype patients were significantly lower than those of CYP3A5*3/*3 genotype patients regardless of whether they were treated with WZ additionally （P＜0.05）. Within 3 months after surgery， although there was no significant difference in the incidence of acute rejection and tacrolimus-related adverse reactions among the four groups （P＞ 0.05）， the incidence of hyperglycemia in patients with CYP3A5*3/*3 was higher （41.67%）. CONCLUSIONS CYP3A5 gene polymorphism is significantly related to tacrolimus c0/D in kidney transplant patients. Under the premise of c0 monitoring of tacrolimus， patients with CYP3A5*1 genotype should be given WZ as soon as possible after surgery to accelerate tacrolimus to reach the therapeutic concentration range， while CYP3A5*3/*3 genotype is not recommended to be given WZ because of the higher risk of hyperglycemia.
RESUMEN
OBJECTIVE To screen the differential components of coumarins in Angelica dahurica from two origins （A. dahurica cv.‘ Hangbaizhi’； A. dahurica cv.‘ Qibaizhi’）. METHODS Non-targeted metabolomics technique of UPLC-Q-Exactive- MS/MS was used to analyze the coumarins in 6 batches of A. dahurica cv. ‘Hangbaizhi’ and 12 batches of A. dahurica cv. ‘Qibaizhi’. The differential components were screened by principal component analysis， partial least squares discriminant analysis and orthogonal partial least squares discriminant analysis. Cluster analysis was performed on differential components. RESULTS A total of 41 coumarins were identified in 18 batches of samples， in which 23 coumarins were differential components. Therein， 6 differential components were higher in content in A. dahurica cv.‘ Hangbaizhi’， while 17 differential components were higher in content in A. dahurica cv.‘ Qibaizhi’. The content of marmesin galactoside in A. dahurica cv.‘ Hangbaizhi’ was significantly higher than that in A. dahurica cv.‘ Qibaizhi’. Based on 23 differential components， A. dahurica cv.‘ Hangbaizhi’ and A. dahurica cv. ‘Qibaizhi’ could be grouped into one category， respectively. CONCLUSIONS The screened differential components of coumarins can be used to distinguish A. dahurica cv. ‘Hangbaizhi’ from A. dahurica cv. ‘Qibaizhi’， especially marmesin galactoside contributed the most， which can be used to identify A. dahurica cv.‘ Hangbaizhi’ and A. dahurica cv.‘ Qibaizhi’.
RESUMEN
Objective@#Excessive daytime sleepiness (EDS) and insomnia symptoms are common in patients with major depressive disorder (MDD), which might lead to a poor prognosis and an increased risk of depression relapse. The current study aimed to investigate the prevalence, and sociodemographic and clinical correlates of EDS and insomnia symptoms among adolescents with MDD. @*Methods@#The sample of this cross-sectional study included 297 adolescents (mean age=15.26 years; range=12–18 years; 218 females) with MDD recruited from three general and four psychiatric hospitals in five cities (Hefei, Bengbu, Fuyang, Suzhou, and Ma’anshan) in Anhui Province, China between January and August, 2021. EDS and insomnia symptoms, and clinical severity of depressive symptoms were assessed using Epworth sleepiness scale, Insomnia Severity Index, and Clinical Global Impression-Severity. @*Results@#The prevalence of EDS and insomnia symptoms in adolescents with MDD was 39.7% and 38.0%, respectively. Binary logistic regression analyses showed that EDS symptoms were significantly associated with higher body mass index (odds ratio [OR]=1.097, 95% confidence interval [CI]=1.027–1.172), more severe depressive symptoms (OR=1.313, 95% CI=1.028–1.679), and selective serotonin reuptake inhibitors use (OR=2.078, 95% CI=1.199–3.601). And insomnia symptoms were positively associated with female sex (OR=1.955, 95% CI=1.052–3.633), suicide attempts (OR=1.765, 95% CI=1.037–3.005), more severe depressive symptoms (OR=2.031, 95% CI=1.523–2.709), and negatively associated with antipsychotics use (OR=0.433, 95% CI=0.196–0.952). @*Conclusion@#EDS and insomnia symptoms are common among adolescents with MDD. Considering their negative effects on the clinical prognosis, regular screening and clinical managements should be developed for this patient population.
RESUMEN
This article highlighted the invaluable expertise of Academician TONG Xiaolin in managing severe cases of COVID-19， thereby providing ideas for the treatment of severe and critically ill patients with SARS-CoV-2 infection by integrating traditional Chinese and western medicine. It is believed that COVID-19 belongs to the “cold dampness epidemic” in traditional Chinese medicine， which is caused by pathogenic qi of cold and dampness. The course of the disease can be divided into four stages： constraint， block， collapse， and deficiency， and the severe cases are mainly in the block and collapse stages. The pathogenesis at the block stage is described as epidemic toxins blocking the lung， which should be treated by diffusing the lung and unblocking the bowels， resolving phlegm and unblocking collaterals. The primary formula used is Zilong Xuanbai Chengqi Decoction （子龙宣白承气汤） with modifications based on individual condition. The pathogenesis at the collapse stage is described as internal block and external collapse， which should be treated by restoring yang to save from collapse， boosting qi to relieve collapse， diffusing the lung and unblocking the bowels， resolving phlegm and unblocking collaterals， usually with the formula Poge Zilong Xuanbai Chengqi Decoction （破格子龙宣白承气汤） with modifications.
RESUMEN
“Cold-dampness entering ying （营）” is the key to the worsening of cold-dampness epidemic， and is more common in the elderly or critically ill cases of cold-dampness epidemic with pathogen exuberance and healthy qi deficiency. This paper reported a case of critically ill COVID-19 combined with multiple organ dysfunction treated by integrative traditional Chinese and western medicine based on “cold-dampness entering ying” theory. The patient did not have high fever after being infected with SARS-Cov-2， but D-dimer continued to increase， and she developed multiple thrombosis throughout the body and multiple organ dysfunctions such as pulmonary embolism， edema， oliguria， and shock. The patient were with enlarged and dusky tongue， with yellow， thick and greasy coating， and sublingual blood stasis， and thready， rapid and rough pulse. All these were characteristic manifestations of “cold-dampness entering ying”， and was differentiated as cold-dampness stasis. For the treatment， symptomatic and supportive western medicine of improving heart function， anti-infection， relieving asthma， stopping cough and reducing phlegm was given as the basic therapy， and additionally， traditional Chinese medicine to open the constraint and the blocked， save from collapse and restore yang， boost qi and relieve collapse， invigorate blood and drain water was used， usually with Modified Poge Zilong Xuanbai Chengqi Decoction （破格子龙宣白承气汤加减）， which was in accordance with the pathogenesis and thus achieving good effect.
RESUMEN
This paper reported a case of severe COVID-19 in the recovery stage with acute lymphoblastic leukemia treated by integrated traditional Chinese and western medicine， with the intention of shedding light on the clinical diagnosis and treatment of similar conditions. The patient， who had acute lymphoblastic leukemia， developed COVID-19 infection during the bone marrow suppression period after chemotherapy. Treatment with western medicine was mainly anti-infection， symptomatic management， and supportive care. During the recovery stage， considering the patient's chemotherapy history and disease progression， the overall syndrome was identified as deficiency of both qi and yin and binding of phlegm and blood. Based on the “state-target” combined treatment strategy， herbal prescriptions were selected and modified to address the “deficiency state”， “disease target”， and “symptom target”. In addition to western medicine， the patient was administered with Shengmai Powder （生脉散） and Compound Zhebei Granules （复方浙贝颗粒） in its modifications to boost qi， nourish yin， and reinforce healthy qi， nourish and cool the blood， ultimately achieving satisfactory therapeutic effects.
RESUMEN
Epidemic cerebrospinal meningitis shows a high degree of consistency with the law of transmission among wei （卫）-qi-ying （营）-blood， in terms of the onset of the season， contagiousness， symptoms， pathogenesis， as well as characteristics of the transmission. It is proposed to use epidemic cerebrospinal meningitis as an example to explore the underlying disease of wei-qi-ying-blood syndrome differentiation system. Epidemic meningitis invades the brain from the upper respiratory tract along the nervous system， and its overall pathogenesis follows from entering the lung system （prodromal period） to entering the blood （bacteremia period， sepsis period） and then entering the brain （shock period）. According to the four-dimensional qualitative principle of epidemic pathogen tropism， it corresponds to disease of both wei and qi syndrome， then blazing of both qi and ying syndrome， and then heat blocking pericardium， exuberant heat stirring wind， and internal block and external collapse syndrome. This article explored the laws of transmission among wei-qi-ying-blood and its underlying diseases described in On Warm Heat （《温热论》）， and revealed the original appearance of the disease model under the laws of transmission among wei-qi-ying-blood to guide the clinical practice.
RESUMEN
OBJECTIVE@#To determine the expression level of Sonic hedgehog (Shh) in the passage of hair follicle stem cells (HFSCs), analyze the effect of Shh overexpression on the proliferation activity of HFSCs, and explore the survival of HFSCs after Shh overexpression and its effect on hair follicle regeneration.@*METHODS@#Hair follicles from the normal area (H1 group) and alopecia area (H2 group) of the scalp donated by 20 female alopecia patients aged 40-50 years old were taken, and the middle part of the hair follicle was cut under the microscope to culture, and the primary HFSCs were obtained and passaged; the positive markers (CD29, CD71) and negative marker (CD34) on the surface of the fourth generation HFSCs were identified by flow cytometry. The two groups of HFSCs were transfected with Shh-overexpressed lentivirus. Flow cytometry and cell counting kit 8 assay were used to detect the cell cycle changes and cell proliferation of HFSCs before and after transfection, respectively. Then the HFSCs transfected with Shh lentivirus were transplanted subcutaneously into the back of nude mice as the experimental group, and the same amount of saline was injected as the control group. At 5 weeks after cell transplantation, the expression of Shh protein in the back skin tissue of nude mice was detected by Western blot. HE staining and immunofluorescence staining were used to compare the number of hair follicles and the survival of HFSCs between groups.@*RESULTS@#The isolated and cultured cells were fusiform and firmly attached to the wall; flow cytometry showed that CD29 and CD71 were highly expressed on the surface of the cells, while CD34 was lowly expressed, suggesting that the cultured cells were HFSCs. The results of real-time fluorescence quantitative PCR and Western blot showed that the expression levels of Shh protein and gene in the 4th, 7th, and 10th passages of cells in H1 and H2 groups decreased gradually with the prolongation of culture time in vitro. After overexpression of Shh, the proliferation activity of HFSCs in the two groups was significantly higher than that in the blank group (not transfected with lentivirus) and the negative control group (transfected with negative control lentivirus), and the proliferation activity of HFSCs in H1 group was significantly higher than that in H2 group before and after transfection, showing significant differences ( P<0.05). At 5 weeks after cell transplantation, Shh protein was stably expressed in the dorsal skin of each experimental group; the number of hair follicles and the expression levels of HFSCs markers (CD71, cytokeratin 15) in each experimental group were significantly higher than those in the control group, and the number of hair follicles and the expression levels of HFSCs markers in H1 group were significantly higher than those in H2 group, and the differences were significant ( P<0.05).@*CONCLUSION@#Lentivirus-mediated Shh can be successfully transfected into HFSCs, the proliferation activity of HFSCs significantly increase after overexpression of Shh, which can secrete and express Shh continuously and stably, and promote hair follicle regeneration by combining the advantages of stem cells and Shh.

Traditional Chinese medicine (TCM) has played an important role in the prevention and treatment of Coronavirus disease 2019 (COVID-19) epidemic in China. The integration of Chinese and Western medicine is an important feature of Chinese COVID-19 prevention and treatment. According to a series of evidence-based studies, TCM can reduce the infection rate of severe acute respiratory syndrome coronavirus 2 in high-risk groups. For patients with mild and moderate forms of COVID-19, TCM can relieve the related signs and symptoms, shorten the period of nucleic-acid negative conversion, and reduce conversion rate to the severe form of the disease. For COVID-19 patients with severe and critical illnesses, TCM can improve inflammatory indicators and blood oxygen saturation, shorten the hospital stay, and reduce the mortality rate. During recovery, TCM can improve patients' symptoms, promote organ function recovery, boost the quality of patients' life, and reduce the nucleic-acid repositive conversion rate. A series of mechanism research studies revealed that capability of TCM to treat COVID-19 through antiviral and anti-inflammatory effects, immune regulation, and protection of organ function via a multicomponent, multitarget, and multipathway approach.

Building on a clear understanding of the diagnosis and treatment patterns for cold-damp epidemics， and incorporating the insights of Academician TONG Xiaolin regarding the differentiation and treatment of such epidemics， this article have distilled the key diagnostic principles. These principles primarily entail observing color and pulse， initially distinguishing between yin and yang， with treatment focusing on dispelling cold and dampness. A comprehensive approach is adopted throughout treatment， with a combination of overall strategies and tailored treatments that evolve in line with the patient's condition. In critical and severe cases， particular attention is given to aspects such as sweating， pulse analysis， and consciousness， preventing the pathogen from penetrating deeply. Efforts are made to open and close organ networks， expelling external pathogens without fixating on resolving constipation. The dosage and efficacy of herbal remedies are adjusted based on individual circumstances and clinical symptoms. The objective is to eliminate pathogens comprehensively， while being vigilant against relapses， ultimately achieving a full recovery. This overview of the thought processes and clinical principles for diagnosing and treating cold-damp epidemics will guide precise clinical practices and provide a theoretical foundation for the involvement of traditional Chinese medicine in epidemic prevention and treatment.
RESUMEN
Objective:To explore the clinical features and risk factors of severe mycoplasma pneumoniae pneumonia(SMPP) in children, and to provide guidance for early identification of SMPP.Methods:The clinical data of 263 children with mycoplasma pneumoniae pneumonia admitted to the Respiratory Department at Anhui Children′s Hospital from January 2019 to December 2021 were analyzed retrospectively.According to the severity of the disease, the patients were divided into severe group( n=88) and mild group( n=175). The general conditions, clinical manifestations, laboratory examination, imaging features and bronchoscopic findings between two groups were compared and statistically analyzed. Results:There was no significant difference in sex and onset season between two groups( P>0.05). The age of severe group was older than that of mild group( P<0.05). According to the age group, the incidence of SMPP in the infant group(14.10%) was lower than that in the preschool group (45.00%) and the school age group (37.65%) ( P<0.05), but there was no significant difference between preschool group and school age group ( P>0.05). The degree of fever and the proportion of extrapulmonary complications in severe group were higher than those in mild group, and the duration of fever, length of hospital stay and use of macrolides in severe group were longer than those in mild group ( P<0.05). There were significant differences in white blood cell count/lymphocyte count, C-reactive protein (CRP), prealbumin, glutamic pyruvic transaminase, lactate dehydrogenase (LDH), immunoglobulin G, immunoglobulin A, procalcitonin, erythrocyte sedimentation rate (ESR) and D-dimer between two groups(all P<0.05). There was significant difference in the copies of mycoplasma pneumoniae DNA in bronchoalveolar lavage fluid between two groups ( P<0.05). The proportion of large shadow, pleural thickening, atelectasis, pleural effusion, bronchoalveolar lavage and airway mucus thrombus blockage in severe group were higher than those in mild group ( P<0.05). Multivariate Logistic regression analysis showed that hot course ( OR=1.294, 95% CI: 1.127-1.485), CRP level( OR=1.027, 95% CI: 1.003-1.052), LDH level( OR=1.006, 95% CI: 1.002~1.011), D-dimer level( OR=1.406, 95% CI: 1.065~1.875), ESR( OR=1.042, 95% CI: 1.008-1.077), large shadow( OR=21.811, 95% CI: 6.205~76.664) and pleural effusion( OR=5.495, 95% CI: 1.604-18.826) were independent risk factors for SMPP.ROC curve analysis showed that thermal path, CRP level, LDH level, D-dimer level and ESR had high predictive value in the diagnosis of SMPP, and the best thresholds were 8.50 d, 25.625 mg/L, 412.50 IU/L, 0.98 mg/L and 36.5 mm/h, respectively. Conclusion:Children with SMPP had high degree of fever, long duration of fever, length of hospital stay, long use of macrolides, significantly increased inflammatory indexes, and severe changes in pulmonary imaging and bronchoscopy.Hot course, CRP level, LDH level, D-dimer level, ESR, large shadow and pleural effusion are risk factors for SMPP.It is helpful for early identification of SMPP when the hot course is >8.50 d, CRP>25.625 mg/L, LDH > 412.50 IU/L, D-dimer > 0.98 mg/L, ESR > 36.5 mm/h.
RESUMEN
Objective:To analyze the expectations and their influencing factors of gynecological examination among female physical examination population.Methods:Convenience sampling method was used to select women undergoing gynecological examinations in the health management center of the Shandong Provincial Hospital Affiliated to Shandong First Medical University between April to June 2021. A face to face interview was conducted with a 20-item structured questionnaire including general information, the women?s feelings about a gynecological examination, expectations of doctors, preferences for the doctor ?s gender, and the presence of chaperones in male doctor examination scenarios. Of the 1 600 questionnaires distributed, 1 583 were valid, with a recovery rate of 98.93%. To compare the preferences for a doctor ?s gender and chaperones with different demographic characteristics, an χ2 test was used. Logistic regression was used to analyze the influencing factors of preferences for doctors ?gender and for chaperones. Results:For a gynecological examination, women were mainly worried about the possibility of bad results (77.4%), while the main expectation to doctors was communication before the examination (49.2%); most women wanted to be examined by a female doctor (85.5%), mainly because they felt relaxed (76.0%); most women did not want chaperones when examined by a female doctor (56.5%), while most of them preferred to be accompanied by a nurse when examined by a male doctor (50.1%). Women whose family income was lower than expenditure and had gynecological examination experiences with male doctors tended to have no preference for a doctor ?s gender. Additionally, there was a strong inverse association between the education level and likelihood of no preference for a doctor ?s gender, that is, the lower the education level, the more likely they were to have no preference for the doctor ?s gender ( P<0.05), when examined by a male doctor. Furthermore, women older than 55 years and who had a gynecological examination more than twice a year, was less likely to need chaperones, while women who had gynecological examination experience with male doctors tended to have no preference for chaperones. Conclusions:Women preferred gynecological examinations to be performed by female doctors who provide gentle and companion staff support during the examinations. Education level, family income, and examination experience of male doctors are the influencing factors for gender preferences of a doctor. Age, examination frequency, and examination experience of male doctors are the influencing factors affecting the preferences of choosing an accompanying person.
RESUMEN
Objective@#This study aimed to estimate the clinical effects of different types of bone-anchored maxillary protraction devices by using a network meta-analysis. @*Methods@#We searched seven databases for randomized and controlled clinical trials that compared bone-anchored maxillary protraction with tooth-anchored maxillary protraction interventions or untreated groups up to May 2021. After literature selection, data extraction, and quality assessment, we calculated the mean differences, 95% confidence intervals, and surface under the cumulative ranking scores of eleven indicators. Statistical analysis was performed using R statistical software with the GeMTC package based on the Bayesian framework. @*Results@#Six interventions and 667 patients were involved in 18 studies. In comparison with the tooth-anchored groups, the bone-anchored groups showed significantly more increases in Sella-Nasion-Subspinale (°), Subspinale-Nasion-Supramentale(°) and significantly fewer increases in mandibular plane angle and the labial proclination angle of upper incisors. In comparison with the control group, Sella-NasionSupramentale(°) decreased without any statistical significance in all treated groups. IMPA (angle of lower incisors and mandibular plane) decreased in groups with facemasks and increased in other groups. @*Conclusions@#Bone-anchored maxillary protraction can promote greater maxillary forward movement and correct the Class III intermaxillary relationship better, in addition to showing less clockwise rotation of mandible and labial proclination of upper incisors. However, strengthening anchorage could not inhibit mandibular growth better and the lingual inclination of lower incisors caused by the treatment is related to the use of a facemask.
RESUMEN
Objective:To report the clinical characteristics, diagnosis, and treatment of 2 cases of X-linked acrogigantism(X-LAG).Methods:The clinical information of two patients were retrospectively reported, and peripheral blood DNA was collected for copy number variations detection.Results:Both patients had onset at age of two, with common clinical characteristics including linear growth acceleration, mild facial coarsening, enlargement of hands and feet, increased appetite, and snoring, etc. The heights Z scores of the two patients before treatment were + 6.86 and + 6.53, respectively. Growth hormone(GH) glucose inhibition test showed that GH nadir values were over 1 ng/mL and insulin-like growth factor-Ⅰ(IGF-Ⅰ) were 586.0 ng/mL and 1 042.0 ng/mL, respectively. Patient 1 received three cycles of octreotide microspheres therapy followed by surgery, and achieved clinical and biochemical remission. Patient 2 had lanreotide for 5.5 years but failed biochemical remission. Microduplication of Xq26.3, which contained pathogenic gene G-protein coupled receptor 101(GPR101), was found in germline DNA of two patients through copy number variation detection, leading to the diagnosis of X-LAG.Conclusion:It should be cautious of X-LAG when children below 2 years old presents symptoms such as overgrowth and so on. Medication combined with surgery is effective.
RESUMEN
Abstract@#Myopia is a common refractive error in the process of development. With the high incidence and low age of myopia in children and adolescents, it has become a worldwide public health problem, seriously endangering physical and mental health. The prevention and control of myopia has a long way to go. Low concentration atropine, as an M type choline receptor inhibitor, has been proved by medical research to effectively delay the progress of myopia. This paper reviews the relevant studies at home and abroad in recent years. The optimal concentration of low concentration atropine, the best clinical regimen and possible potential side effects were discussed. From the point of view of school public health, this paper discusses the significance of low concentration atropine for the prevention and control of myopia among school age students, in order to provide a reliable basis and new ideas for the follow up clinical application of atropine and myopia prevention and control strategies for school students.
RESUMEN
Objective:To investigate the relationship between abdominal visceral adipose tissue (VAT) and cardiometabolic risk (CMR) through quantitative computed tomography (QCT).Methods:The present study included 76226 participants. Abdominal fat areas were measured using the QCT Pro Model 4 system. Cardiometabolic indices were collected, including systolic and diastolic blood pressures, fasting plasma glucose, total cholesterol, triglyceride, and low-density and high-density lipoprotein cholesterols CMR score was the sum of abnormal blood pressure, fasting glucose, triglyceride, and high-density lipoprotein cholesterol. Restricted cubic spline and ordered logistic regression models were applied.Results:The mean age was 50±13 years and the percentage of men was 58.8%. The level of VAT area was higher in men than in women (191.7±77.1 cm 2 vs 116.4±56.2 cm 2, P<0.0001 for all). After adjustment for age, the cardiometabolic indices except high-density lipoprotein cholesterol increased with increasing VAT area. When VAT area was 300 cm 2, age-adjusted odds ratios and 95% confidence intervals of a CMR score ≥ 1 were 14.61 (13.31, 16.04) for men and 5.46 (4.06, 7.36) for women, and the age-adjusted probability of a CMR score ≥ 3 was 31.7% for men and 31.3% for women. Conclusions:QCT-derived VAT is closely related to CMR. The findings suggest that measurement of visceral fat is recommended for the management of abdominal obesity in subjects who agree to undergo lung cancer screening via low-dose CT without additional radiation exposure.
RESUMEN
The measurement of serum alkaline phosphatase (ALP) levels has been widely used in the clinical setting. However, isolated elevation of serum ALP levels is also commonly seen and needs to be extensiuely evaluated Herein, we present a case of gastric adenocarcinoma with disseminated carcinomatosis of the bone marrow (DCBM). In this case, isolated elevation of serum ALP levels was the only clinical manifestation with no other notable symptom. Additionally, imaging studies including whole body computed tomography (CT) and positron emission tomography-CT (PET-CT) were all negative, which resulted in the misdiagnosis of Paget′s disease of bone initially. This highlights that malignancies involving bones presenting with isolated elevation of serum ALP levels might be misdiagnosed in asymptomatic individuals.
RESUMEN
It is shown that phytochemicals have a protective effect on colon cancer. Curcumin, polysaccharides (apple polysaccharides, mushroom glucans), saponins (paridis saponins, ginsenosides), resveratrol, quercetin and other plant drugs can inhibit colon cancer cell proliferation and promote cell apoptosis through different signaling pathways. In addition, it also has anti-inflammatory, antioxidant, anti-angiogenesis, reduce the toxic side effects of chemotherapy drugs, and reverse the drug resistance of tumor cells. Understan-ding the prevention and cure effect of plant medicine on colon cancer and its possible mechanism can provide more theoretical basis and therapeutic ideas for the clinical prevention and cure of colon cancer.
RESUMEN
Objective@#To explore the effects of ambient fine particulate matter（PM2.5）exposure on semen quality in healthy adult men .@*Methods@#The semen quality data were collected from the pre-pregnancy check outpatient of Taizhou Central Hospital from August 2014 to December 2017,excluding the patients with any disease of reproductive system. The data of daily pollutant concentration of this area during the same period were also collected to estimate the exposures of PM2.5,PM10,SO2,NO2,O3 and CO during 90 days before each semen examination. Logistic regression model was applied to estimate the association between PM2.5 exposure and semen quality .@*Results@#A total of 3 456 healthy adult men were included in this study. The median （interquartile range）of the total sperm count of the 3 456 subjects was 161.00（122.00）×106,and 94.40% of the subjects could reach the lower reference limit for sperm count. The median（interquartile range）of the sperm concentration was 22.20（18.80）×106/mL,and 69.50% of the subjects were qualified. The median（interquartile range）of the sperm vitality was 55.30%（23.37%）,and 44.10% of the subjects were qualified. The median（interquartile range）of daily average concentration of PM2.5 at 0-90 days before semen examination was 37.82（12.33）μg/m3. The results of multivariate logistic regression model showed that,with each 12.33 μg/m3 increase of PM2.5 exposures at 0-90 days before semen examination,the odds ratios of unqualified sperm concentration,sperm motility and sperm vitality were 1.236（95%CI：1.041-1.466）,1.493（95%CI：1.260-1.770）and 1.462（95%CI：1.246-1.715）,respectively .@*Conclusion@#The results suggested that high concentration of ambient PM2.5 exposure during the sperm development period negatively affects sperm concentration,sperm motility and sperm vitality.
