RESUMEN

Birth defect and perinatal death are major public issues threatening the health of women and children in China. However, perinatal death attributed to birth defects has not yet received sufficient attention. To minimize the occurrence of perinatal death caused by birth defects, this review article deeply analyzed the current status of epidemiology, clinical, and basic research on perinatal death attributed to birth defects both domestically and internationally, and proposed to encourage the conduct of national research on perinatal causes. We should also pay attention to the application of the perinatal cause of death classification system, and focus on accurate diagnosis and the three-level prevention and control of perinatal death attributed to birth defect.

RESUMEN

Objective: To investigate the relationship between maternal exposures to peri-conceptional risk factors and the risk of hypospadias and cryptorchidism in offspring. Methods: Pregnant women who delivered male newborns and participated in the China birth cohort study between February 2018 and December 2020 at the research center of Beijing Obstetrics and Gynecology Hospital, Capital Medical University were selected for the study. All were enrolled at 6-13+6 weeks of their gestation. Baseline risk factor information was collected by questionnaire survey. Information on the outcome of hypospadias and cryptorchidism was obtained by clinical examination at birth and ultrasonography. Logistic regression was used to analyze the Odds Ratio (OR) and 95% Confidence Interval (95%CI) of each factor with respect to the onset of the outcome. Results: A total of 15, 833 pregnant women with an average age of (31.81±3.84) years were included. Among their offsprings, 113 were diagnosed as hypospadias or cryptorchidism (42 hypospadias, 69 cryptorchidism, and 2 both hypospadias and crypterchidism), with an incidence of 7.14‰. The results of multivariate logistic regression analysis showed that mothers with pregnancy history of birth defects (OR=3.01, 95%CI: 1.09-8.35), with preconception Hepatitis B infection (OR=4.74, 95%CI: 1.10-20.42), fetal growth restriction (OR=4.02, 95%CI: 2.10-7.68), multivitamin use since preconception (OR=1.98, 95%CI: 1.12-3.52), and never cook and eat at home (OR=2.17, 95%CI: 1.23-3.82) were risk factors for hypospadias and cryptorchidism (all P<0.05). Conclusions: Obesity in early pregnancy, preconception Hepatitis B infection, pregnancy history of birth defects, fetal growth restriction, multivitamin use before pregnancy, and rarely cook and eat at home were associated with an increased risk of hypospadias or cryptorchidism in their offsprings.

RESUMEN

Objective: To analyze the association between maternal blood pressure and congenital heart disease (CHD) in offspring. Methods: From February 2018 to December 2020, pregnant women who participated in the China birth cohort study in Beijing Obstetrics and Gynecology Hospital, Shenzhen Maternal and Child Healthcare Hospital and Chengdu Women's and Children's Central Hospital were enrolled in this study. The baseline and follow-up information were collected using an electronic data collection system. Stepwise logistic regression model was used to analyze the association between maternal blood pressure including systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and pulse pressure difference (PP) in the first trimester of pregnancy and the risk of CHD in the offspring. A restrictive cubic spline curve was used to draw the dose-response curve between maternal blood pressure and CHD. Results: A total of 55 552 participants were included in this study. Of them, 31 038, 15 375 and 9 139 pregnant women were enrolled in Beijing Obstetrics and Gynecology Hospital, Shenzhen Maternal & Child Healthcare Hospital and Chendu Women's and Children's Central Hospital, respecitively. The age of pregnant women was (31.3±4.0) and the incidence of CHD in the offspring was 0.78% (435/55 552). Multivariable logistic regression model analysis showed that the increase of SBP (OR=1.01, 95%CI: 1.00-1.02), DBP (OR=1.01, 95%CI: 1.00-1.03) and MAP (OR=1.02, 95%CI: 1.00-1.03) in the first trimester were significantly associated with the risk of CHD in the offspring. The restrictive cubic spline analysis showed a positive linear association of SBP (Ptotal<0.001; Pnon-liear=0.315), DBP (Ptotal<0.001; Pnon-liear=0.928) and MAP (Ptotal<0.001; Pnon-liear=0.929) with the risk of CHD in the offspring. Conclusion: Maternal SBP, DBP and MAP in the first trimester of pregnancy were positively associated with the risk of CHD in the offspring.

RESUMEN

OBJECTIVE: This study delves into the role of N-terminal propeptide type III collagen (PIIINP) in the diagnosis and management of liver pathological changes associated with non-alcoholic steatohepatitis (NASH). PATIENTS AND METHODS: We collected baseline information, pathological data, and serum PIIINP levels of 168 patients diagnosed with non-alcoholic fatty liver disease (NAFLD) via ultrasound imaging in our hospital. Based on the non-alcoholic fatty liver disease activity score (NAS), patients with different NAFLD patterns were divided into a Definite NASH group and a Not/borderline group. Differences in PIIINP levels and pathological features between the two groups were compared and analyzed. The diagnostic value of PIIINP for NASH was evaluated using the receiver operating characteristic (ROC) curve. RESULTS: Patients with NASH exhibited significantly higher values of homeostatic model assessment for insulin resistance (HOMA-IR), fibrosis biomarker fibrosis-4 (FIB-4), aminotransferase-to-platelet ratio index (APRI), and serum PIIINP levels than those classified as Not/borderline. A marked increase in the serum concentrations of PIIINP was observed with the severity of fatty degeneration, lobular inflammation, and hepatocellular ballooning. The AUC of PIIINP for diagnosing definite NASH was 0.766 (95% CI: 0.694, 0.839), APRI was 0.634 (95% CI: 0.549, 0.718), and FIB-4 was 0.621 (95% CI: 0.534, 0.708). The AUC of PIIINP for diagnosing definite NASH was significantly higher than that of APRI and FIB-4 (all p<0.05). Utilizing the predetermined threshold values for diagnostic parameters, the PIIINP measure demonstrated a sensitivity of 71.6% and a specificity of 73.6% in diagnosing definitive NASH when its value exceeded 7.72 ng/dL. This yielded a Youden index of 0.45. Similarly, when the APRI measure exceeded 0.21, it exhibited a sensitivity of 60.5% and a specificity of 63.2%, resulting in a Youden index of 0.24. Moreover, when the FIB-4 index surpassed 0.26, it showed a sensitivity of 46.9% and a specificity of 79.3%, culminating in a Youden index of 0.26. CONCLUSIONS: NASH patients in this study exhibited significantly elevated PIIINP serum levels, which were closely associated with hepatocyte pathological changes. PIIINP demonstrated superior competence in diagnosing NASH than APRI and FIB-4 and thus offers a viable alternative for the clinical diagnosis of NASH.

RESUMEN

Objective: To analyze the efficacy and safety of first-line treatment with an anti-CD38 monoclonal antibody regimen for primary plasma cell leukemia (pPCL). Methods: Patients diagnosed with pPCL from December 1st, 2018 to July 26th, 2023, receiving first-line treatment of anti-CD38 monoclonal antibody-based regimens across multiple centers including Peking University People's Hospital, Fuxing Hospital of Capital Medical University, Qingdao Municipal Hospital, Shengjing Hospital of China Medical University, Handan Central Hospital, the First Affiliated Hospital of Harbin Medical University, the Fourth Hospital of Hebei Medical University and General Hospital of Ningxia Medical University were consecutively included. A total of 24 pPCL patients were included with thirteen being male and eleven being female. The median age [M(Q1, Q3)] was 60 (57, 70) years. Patients were grouped according to peripheral blood plasma cell (PBPC) percentage [5%-19% (n=14) vs ≥20% (n=10)]. Last follow-up date was September 26th, 2023. The median follow-up period was 9.1 (4.2, 15.5) months. Patients' data related with clinical baseline characteristics, efficacy, survival and safety were retrospectively collected. Cox proportional hazards regression model was used to analyze risk factors associated with survival. Results: Among 24 pPCL patients, 16 (66.7%) patients had anemia at diagnosis, 13(54.2%) patients had thrombocytopenia, 8 (33.3%) patients had a baseline estimated glomerular filtration rate (eGFR)<40 ml·min-1·(1.73m2)-1, 13 (54.2%) patients had elevated lactate dehydrogenase (LDH) levels. The median PBPC percentage was 16% (8%, 26%) . Fluorescence in situ hybridization testing indicated that patients harboring 17p deletion, t(4;14) or t(14;16) were 6 (25.0%), 4 (16.7%) and 4 (16.7%), respectively. The overall response rate was 83.3% (20/24). The median progression-free survival (PFS) was 20.5 (95%CI: 15.8-25.2) months, and the median overall survival (OS) was not reached. Estimated 1-year and 2-year PFS and OS rates were 75.0% and 89.1%, 37.5% and 53.4%, respectively. The median PFS and OS for patients with PBPC percentages 5%-19% and≥20% were not reached and 20.5 (95%CI:15.7-25.3) months, 17.8 months and not reached, respectively. There was no significant statistical difference of PFS and OS between two groups (all P>0.05). Multivariate Cox regression analysis showed that 1p32 deletion was the risk factor associated with PFS (HR=7.7, 95%CI: 1.1-54.9, P=0.043). Seventeen patients (70.8%) developed grade 3-4 hematologic toxicities. Twelve patients (50.0%) developed grade 3-4 thrombocytopenia. Sixteen patients (66.7%) developed infection. All hematologic toxicities and infections were improved after supportive treatment. Conclusion: First-line treatment with anti-CD38 monoclonal antibody-based therapy for pPCL is effective and safe.

RESUMEN

Objective: To investigate the expression change of the Mas1 receptor in the placenta of healthy pregnant women during different gestation periods, analyze the expression level of the Mas1 receptor in the placenta of pre-eclampsia (PE) patients, and its biological function in trophoblast cells. Methods: Placental villous tissues were collected from normal pregnant women in early, mid and late pregnancy. Human trophoblast stem cells were isolated and cultured from early pregnancy villous tissues. The expression of the Mas1 receptor was detected by fluorescence immunoassay and real-time fluorescence quantitative PCR. In a case-control study, patients with full-term PE were selected as the case group and healthy women with full-term pregnancy were selected as the control group. Placental villus tissues were collected from both groups. Immunofluorescence chemistry and immunoprotein blotting were used to study the changes in Mas1 receptor expression in PE. Mas1 receptor agonists and blockers induced HTR8/Svneo cells and BeWo cells, and the effects of the Mas1 receptor on the proliferation and migration of trophoblast cells were detected by the CCK8 proliferation test and scratch test. Results: Eight cases were included in early pregnancy, seven cases in mid-pregnancy and six cases in late pregnancy. Mas1 receptors in normal placental villi tissue were mainly expressed in human trophoblast stem cell membranes and cytoplasm, and the expression of Mas1 receptor mRNA in villi tissue was significantly higher in late pregnancy than in mid-pregnancy. There were 24 cases included in the case group and 12 cases in the control group. Mas1 receptor expression in placental villi was significantly lower in the case group compared to the control group; Activation/inhibition of the Mas1 receptor had no significant effect on the proliferation of HTR8/Svneo cells and BeWo cells. Activated Mas1 receptor had no significant effect on the migration ability of HTR8/Svneo cells. Conclusion: Mas1 receptors are expressed in placental villous tissue and their expression varies with gestation. Mas1 receptor expression is reduced in PE patients, but it does not affect the value-added or migratory function of trophoblast cells.

RESUMEN

Objective: To analyze the incidence of preterm birth based on pre-pregnancy body mass index (BMI) stratification and explore the associated factors of preterm birth among pregnant women at different BMI stratifications. Methods: From February 2018 to December 2020, pregnant women who participated in China Birth Cohort Study (CBCS) and gave birth at Beijing Obstetrics and Gynecology Hospital were enrolled as the study subjects. Electronic Data Capture System and standard structured questionnaires were used to collect data related to pre-pregnancy, pregnancy, and delivery for pregnant women. Pregnant women were divided into the low-weight group, normal-weight group and overweight group based on their pre-pregnancy BMI. A Cox proportional hazards model was used to analyze the associated factors of preterm birth among pregnant women with different BMI before pregnancy. Results: A total of 27 195 singleton pregnant women were included, with a preterm birth rate of 5.08% (1 381/27 195). The preterm birth rates in the low-weight group, normal-weight group and overweight group were 4.29% (138/3 219), 4.63% (852/18 390) and 7.00% (391/5 586) respectively (P<0.001). After adjusting for relevant factors, the Cox proportional hazards model showed that the risk of preterm birth in the overweight group was 1.457 times higher than that in the normal-weight group (95%CI: 1.292-1.643). Preeclampsia-eclampsia (HR=2.701, 95%CI: 1.318-5.537) was the associated factor for preterm birth in the low-weight group. Advanced maternal age (HR=1.232, 95%CI: 1.054-1.441), history of preterm birth (HR=4.647, 95%CI: 3.314-6.515), vaginal bleeding in early pregnancy (HR=1.613, 95%CI: 1.380-1.884), and preeclampsia-eclampsia (HR=3.553, 95%CI: 2.866-4.404) were associated factors for preterm birth in the normal-weight group. Advanced maternal age (HR=1.473, 95%CI: 1.193-1.818), history of preterm birth (HR=3.209, 95%CI: 1.960-5.253), vaginal bleeding in early pregnancy (HR=1.636, 95%CI: 1.301-2.058), preeclampsia-eclampsia (HR=2.873, 95%CI:2.265-3.643), and pre-gestational diabetes mellitus (HR=1.867, 95%CI: 1.283-2.717) were associated factors for preterm birth in the overweight group. Conclusion: Pre-pregnancy overweight is an associated factor for preterm birth, and there are significant differences in the associated factors of preterm birth among pregnant women with different BMI before pregnancy.

RESUMEN

Objective: To explore the association between coagulation function indicators and placental abruption (PA) in different trimesters of pregnancy among preeclampsia-eclampsia pregnant women. Methods: From February 2018 to December 2020, pregnant women who participated in the China birth cohort study and were diagnosed with preeclampsia, eclampsia and chronic hypertension with superimposed preeclampsia in Beijing Obstetrics and Gynecology Hospital were enrolled in this study. The baseline and follow-up information were collected by questionnaire survey, and the coagulation function indicators in the first and third trimesters were obtained through medical records. The Cox proportional hazards model was used to analyze the association between the coagulation function indicators and PA. A restrictive cubic spline curve was used to draw the dose-response curve between the relevant coagulation function indicators and PA. Results: A total of 1 340 participants were included in this study. The age was (32.50±4.24) and the incidence of PA was 4.4% (59/1 340). After adjusting for relevant factors, Cox proportional hazards model showed that compared with the high-level classification of fibrinogen (FIB), participants within the middle-(HR=3.28, 95%CI: 1.27-8.48) and low-level (HR=3.84, 95%CI: 1.40-10.53) classification during the first trimester and within the low-level classification (HR=4.18, 95%CI: 1.68-10.39) during the third trimester were more likely to experience PA. Compared with the middle-level classification of pro-thrombin time (PT), the risk of PA in the participants within the low-level classification (HR=2.67, 95%CI: 1.48-4.82) was significantly higher in the third trimester. The restrictive cubic spline analysis showed a linear negative association between FIB and PA in the first and third trimesters, while PT and PA showed an approximately L-shaped association. Conclusion: Among pregnant women diagnosed with preeclampsia-eclampsia, the middle-and low-level classification of FIB in the first and third trimesters and the low-level classification of PT in the third trimester could increase the risk of PA.

RESUMEN

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

RESUMEN

Cardiogenic stroke, manifested as a clinical syndrome in which emboli from the heart and aortic arch pass through the circulation and cause cerebral artery embolism and corresponding brain dysfunction, accounts for 20% to 30% of all ischemic strokes. Regarding the etiological classification, the boundary between cardiogenic stroke and cryptogenic stroke, especially embolic stroke of undetermined source (ESUS), as well as aortic arch atheromas categorization remain uncertain. Concerning the diagnosis, the criteria need to be formulated and unified, and thus the author proposes new diagnostic criteria. With regard to the treatment, anticoagulation therapy should be started or restarted several days to several weeks after the onset of stroke (e.g., atrial fibrillation-related), and treatment during acute phase and for prevention of stroke recurrence should be initiated after multi-disciplinary consultation.

RESUMEN

Objective: To explore the clinical effects of pulsed dye laser (PDL) dynamically combined with triamcinolone acetonide (TAC) in the treatment of keloids. Methods: A retrospectively observational study was conducted. From April 2015 to October 2020, 34 keloid patients (46 keloids) who met the inclusion criteria were admitted to Huaihe Hospital of Henan University. The patients were divided into TAC group and dynamic treatment group according to their treatment methods. There were 18 patients (26 keloids) in TAC group, including 8 males and 10 females, aged (30±12) years, who were treated with TAC injection alone. There were 16 patients (20 keloids) in dynamic treatment group, including 6 males and 10 females, aged (26±11) years, who were treated with TAC injection, PDL, or PDL combined with TAC injection according to the Vancouver scar scale (VSS) score before each treatment. Before the first treatment (hereinafter referred to as before treatment) and 12 months after the first treatment (hereinafter referred to as after treatment), the keloids were assessed by VSS, patient and observer scar assessment scale (POSAS), and the effect of keloids on the quality of life of patients was evaluated with dermatology life quality index (DLQI) scale. Twelve months after treatment, the curative effect of keloid was evaluated according to the VSS score and the effective rate was calculated. The first effective time and the cumulative times of TAC injection at the first effective time, the number of follow-up and the occurrence of adverse reactions of keloids within 12 months after treatment were recorded, and the incidence of adverse reactions was calculated. Data were statistically analyzed with paired sample t test, independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: The total VSS scores of patients' keloids in TAC group and dynamic treatment group 12 months after treatment were significantly lower than those before treatment (with t values of 7.53 and 8.09, respectively, P<0.01), and the total scores of pigmentation and vascularity in VSS and POSAS, the total POSAS score, and the DLQI scale score were significantly lower than those before treatment (with Z values of -3.71, -4.04, -4.21, -4.11, -3.76, -3.73, -3.92, and -3.93, respectively, P<0.01). The total scores of pigmentation and vascularity in VSS and POSAS of patients' keloids in dynamic treatment group 12 months after treatment were significantly lower than those in TAC group (with Z values of -2.03 and -2.12, respectively, P<0.05). Twelve months after treatment, the effective rate of patients' keloids in dynamic treatment group was significantly higher than that in TAC group (χ2=3.88, P<0.05). The first effective time of patients' keloids in dynamic treatment group was 5.5 (2.0, 6.0) months, which was significantly shorter than 6.0 (2.3, 10.3) months in TAC group (χ2=4.02, P<0.05). The cumulative times of TAC injection at the first effective time of patients' keloids in dynamic treatment group was 3.2±1.7, which was significantly less than 4.2±1.8 in TAC group (t=2.09, P<0.05). The number of follow-up of patients' keloids within 12 months after treatment in dynamic treatment group was significantly more than that in TAC group (t=-2.94, P<0.01), and the total incidence of adverse reactions was lower than that in TAC group but without statistically significant difference (P>0.05). Conclusions: Compared with TAC injection alone, PDL dynamically combined with TAC in the treatment of keloid can shorten the effective time, reduce the number of TAC injection, and improve the patient's compliance and clinical efficacy.

RESUMEN

The current study summarized the clinical characteristics of 8 patients with central nervous system anaerobic infections who visited the Second Hospital of Hebei Medical University from June 2019 to June 2021. Among the 8 patients, 7 cases had headache and fever as the first symptoms, and 1 case had left-sided limb weakness as the first symptom. Four patients had a previous history of diabetes (1 patient had a history of tooth extraction before the onset of the disease), 1 patient had a previous history of sinusitis, 1 patient had a history of tooth extraction before the onset of the disease, and 2 patients had chronic extensive periodontitis or periapical periodontitis. Five cases showed abnormal intracranial and/or meningeal enhancement on cranial magnetic resonance imaging (MRI), and 1 case showed swelling of the whole brain tissue on cranial computed tomography (CT). After treatment, symptoms of 4 cases were improved, symptoms of 1 case were aggravated, and 3 cases died. Anaerobic infections can occur in various parts of the body:the central nervous system, oral cavity, head and neck, chest, abdomen, pelvis, skin and soft tissues. It is generally believed that anaerobic bacteria rarely cause central nervous system infection, therefore, anaerobic culture of cerebrospinal fluid is usually not performed. Moreover, anaerobic culture is affected by many factors, and thus it is difficult to obtain positive results. Metagenomic next-generation sequencing can identify multiple pathogens (viral, bacterial, fungal, or parasitic) from samples based on DNA and/or RNA sequences and has advantages in diagnosing anaerobic infections of the central nervous system. Prompt empirical antimicrobial therapy is essential for the prognosis of the patients.

RESUMEN

Objective: To investigate the reoperation and perioperative management of residual cyst wall with perineal intractable sinus after resection of presacral cyst tumors. Methods: The clinical data of 29 patients with residual cyst wall and perineal intractable sinus after resection of presacral cyst tumors in Affiliated Cancer Hospital of Zhengzhou University from January 2014 to August 2019 were reviewed, including the characteristics of the residual cyst wall with perineal intractable sinus after resection of presacral cyst tumors, surgical method, and perioperative management. Results: Twenty-nine patients with residual cyst wall and perineal intractable sinus after resection of presacral cyst tumors, including 9 cases of epidermoid cysts, 7 cases of dermoid cysts, 10 cases of mature teratomas and 3 cases of malignant cysts (including malignant transformation of caudate cyst and teratoma); The 29 patients underwent posterior approaches for cyst resection in other hospital before, of whom 1 patient underwent posterior combined with transabdominal approach. All of thes patients underwent resection of residual presacral cyst wall and perineal intractable sinus in our hospital, of whom 25 patients underwent a transperineal approach through an arc-shaped incision anterior to the apex of the coccyx, and the other 4 patients underwent transperineal arc-shaped incision combined with transabdominal approach. All of the patients were cured without serious complications occurring, postoperative pathological and the magnetic resonance imaging diagnosis showed that the residual cyst wall and perineal intractable sinus were all completely removed. Conclusion: Appropriate surgical approache and perioperative treatment for the patients with residual cyst wall and perineal intractable sinus are very important to promote the resection of residual cyst wall and the healing of perineal intractable sinus.

RESUMEN

Yi Zang Shu Mu(, The List of Medicine Books), written by Yin Zhongchun, is China's earliest medical bibliographer. The years of birth and death of Yin Zhongchun was unknown. By text research, it is confirmed that Yin Zhongchun was born in the 20th Year of Jiajing in Ming Dynasty (1541) and died in the First Year of Tianqi(1621). The only currently existing block-printed edition of Yi Zang Shu Mu is the Fan Xingzhun Qi Fen Shi edition in the library of China Academy of Chinese Medical Sciences. The copies in Japan lack the words " Proofread by Yun Jian Chen Jiru Meigong" , but have an extra preface written by Chen Yidian. This fact indicates that the original of the Japanese copy might be different from the Chinese edition.

RESUMEN

OBJECTIVE: To explore the effects of low-level long-term occupational exposure to chromate on the health of workers, and the potential biomarkers of early health effects in terms of lung function, immune toxicity and genetic damage. METHODS: A total of 22 chromate contact workers and 44 non-chromate contact workers from an electroplating enterprise with long-term occupational environment monitoring in line with the national standards in Inner Mongolia were investigated. The questionnaire survey was conducted to collect the basic situation, the history of smoking, drinking, diseases and so on. The portable lung function instrument, inductively coupled plasma mass spectrometry and cytokinesis-blocked micronucleus test were performed to measure the chromate contact workers'lung function, whole blood Cr (WB-Cr) and micronuclei frequency (MNF) of peripheral blood lymphocytes respectively. The cytometric bead array was used to detect the levels of IL-1ß, IL-6, IL-8, IL-10, IL-12P70 and TNFα in the serum among the two groups. The effects of chromate exposure on the above-mentioned indexes involved biological exposure, lung function, immune response and genetic damage, and their correlation were analyzed with different statistical methods. RESULTS: (1) the average length of service for chromate contact workers was 31 years, and their concentration of WB-Cr was 1.11-4.19 µg/L. They were divided into high and low exposure groups according to the median of 1.72 µg/L. The WB-Cr in the high exposure group (2.17 µg/L) was higher than that in the low exposure group (1.58 µg/L) as well as the reference value of the healthy population (1.74 µg/L, P<0.05); (2) the lung function test showed 10 (45.45%) chromate exposure workers had single or multiple abnormal lung function indexes, among which large airway injury index PEF, and small airway injury indexes MVV and FEF25%-75% were all negatively correlated with WB-Cr (r=-0.53, P<0.05; r=-0.52, P<0.05; r=-0.44, P<0.05); (3) IL-1ß, IL-6, IL-8 and TNFα in the serum of chromate contact workers were higher than those in the control group (P<0.05), and there was a positive correlation between TNFα and WB-Cr, and among these cytokines (P<0.05); (4) the average lymphocyte MNF in chromate contact workers was 1.341%, higher than the reference value of the general population (0.436%, P<0.01). Poisson regression analysis showed MNF in thehigh exposure group was higher than that in the low exposure group, OR (95%CI) =1.323 (1.049, 1.669); (5) multiple linear regression analysis showed that the lung function index FEF25%-75% decreased with the increase of TNFα (P<0.05), no significant correlation was found between other cytokines, MNF and lung function indexes. CONCLUSION: Long-term low-level occupational exposure to chromate can cause the decline of lung function, immune inflammatory reaction and genetic damage in workers, in which local or systemic inflammatory response is associated with decreased lung function. Lung function indexes PEF, FEF25%-75% and MVV, serum cytokines IL-1ß, IL-6, IL-8, and TNFα, and peripheral blood lymphocyte MNF may be used as early health effects biomarkers of chromate exposure.

RESUMEN

Objective: To explore short-term effect of intense pulsed light (IPL) combined with meibomian gland expression in treating meibomian gland dysfunction (MGD). Methods: This study was a prospective, randomized, double-masked, controlled study. Forty-four MGD patients were enrolled in the study and received three consecutive IPL treatments with an interval of 4 weeks. One eye of each patient was randomly assigned as the study eye receiving the IPL therapy with an energy of 14-16 J/cm(2), and the fellow eye was as the control eye receiving a placebo therapy with 0 J/cm(2). Meibomian gland expression was immediately performed after the IPL treatment in both eyes. Efficacy was evaluated through assessment of the meibomian gland yielding secretion score (MGYSS) , SPEED questionnaire, tear film break-up time (TBUT), cornea fluorescein staining and infrared meibography. Safety was evaluated through best spectacle corrected visual acuity, intraocular pressure, slit lamp examination and fundus examination. These examinations were performed before and after each treatment. Results: Significant improvements were observed in the MGYSS and TBUT after IPL treatments (P<0.05). The improvements compared to the baseline of MGYSS at the upper eyelid in the treatment eyes were significantly higher than those in the control eyes after the first treatment (Z=-2.036, P=0.003). The improvements compared to baseline of MGYSS at the lower eyelid and the TBUT in the treatment eyes were significantly higher than those in the control eyes after the second treatment (Z=-2.999 and -2.036, respectively P=0.007 and 0.042, respectively). SPEED and cornea fluorescein staining were decreased in both eyes after IPL treatments, but there was no statistical difference between the two eyes. No obvious complication was observed in the study. Conclusions: IPL treatment combined with meibomian gland expression is an efficient and safe therapy, and can increase meibomian gland yielding secretion, increase the TBUT, relieve the symptoms and repair the corneal epithelium defects for MGD eyes.

RESUMEN

The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) in APM1 contribute to disorders of lipid metabolism in hypertensive disorder complicating pregnancy (HDCP). The study included 178 pregnant women with HDCP and 243 healthy pregnant controls. Using PCR-restriction fragment length polymorphism, we detected the frequencies of genotypes, alleles, and haplotypes of two SNPs, +45T>G (rs2241766) and +276G>T (rs1501299), in APM1. We found that the SNP +276 TT genotype was significantly associated with protection against HDCP compared to the pooled G genotypes. The genotype and allele frequency distributions of SNP +276 were significantly different between the cases and controls. Single-point genotype and allele distributions in SNP +45 were not statistically different between the groups. The pooled G haplotypes were significantly overrepresented in the case group compared to the TT haplotype. Plasma adiponectin (APN) concentration was determined by enzyme-linked immunosorbent assay, and we found that APN levels in cases were significantly lower than those in controls. Using the clinical data, we evaluated the correlation between the two SNPs and HDCP development, and revealed an association between the two SNPs and disorders of lipid metabolism in patients with HDCP. Except for fasting insulin levels, which was higher in cases than in controls, there were no significant differences in the other clinical data between the two groups.

RESUMEN

The aims of this study were to establish a random amplified polymorphic DNA (RAPD) fingerprint database of chloroplast DNA (cpDNA) from different cultivars of Cornus officinalis and to convert RAPD markers to sequence characterized amplified regions (SCAR) markers. A method of extraction was established that was suitable for obtaining cpDNA from samples rapidly dried in silicone; an RAPD fingerprint database was built; and the genetic distance between samples was used as statistical clustering variables for calculating DICE genetic similarity coefficients and for building a kinship tree chart. RAPD markers were converted to SCAR markers to design specific primers, and samples from C. officinalis cultivars, plants of the same family, and its adulterants, were used for amplification and identification. Fifteen amplified primers with stable polymorphisms were screened for amplification of 130 copies of materials. In total, 57 sites were achieved, 40 of which were polymorphic, and the polymorphic rate was up to 70.18%. A genetic tree was built based on seven cultivars. SCAR markers of C. officinalis cpDNA were successfully converted into RAPD markers. cpDNA samples from hawthorn, C. officinalis, Cornus wood, and grape were used for SCAR amplification, and their bands were distinctly different. In conclusion, SCAR markers and cpDNA may be used for research on C. officinalis and its adulterants, and the results may provide a basis for identifying germplasm and screening fine varieties at a molecular level.

RESUMEN

Genotyping that differentiates between strains of Mycobacterium tuberculosis based on variations in the genome of the organism is a useful tool for molecular epidemiological studies of tuberculosis. In the present study, we identified a combination of five mycobacterial interspersed repetitive unit (MIRU) loci and three variable numbers of tandem repeats (VNTR) loci of M. tuberculosis that showed a discriminatory power comparable to that of the 15 to 24 loci-based typing proposed for international standardisation in analysing 210 paediatric isolates obtained from Chongqing, China.
