ABSTRACT

ObjectiveTo establish the Shanghai twin birth cohort (STBC) and analyze the effects of genetic factors, shared environment, and non-shared environment interactions on birth health and growth and development of newborns. MethodsBased on the population-wide birth cohort in Shanghai, a comprehensive survey was conducted on the families with double and multiple babies born after January 1, 2015 to collect information on birth health, growth and development, and the family environment of the babies. ResultsBy December 31, 2021, a total of 7 195 pairs (14 405 cases) of twins were successfully included in the STBC survey. The average birth length of twins was 47.2 cm and average birth weight was 2 465.3 g. Heterozygous twins accounted for 69.05% and preterm babies accounted for 57.07%. The average age of the mothers of twins was 31.82 years, and the average age of the fathers was 33.87 years, with more than 80% of the parents having a college degree or above. 44.50% of the mothers used assisted reproductive technologies, 7.40% had illnesses during pregnancy, and 15.90% were exposed to passive smoking during pregnancy. During the survey period, the average monthly increase in the length of the twin infants was 2.09 cm, and the average monthly weight gain was 0.53 kg. ConclusionThe incidence of adverse outcomes such as maternal cesarean section rate, preterm birth, and low birth weight is higher in the twin birth population. Information on birth health as well as growth and development in childhood and adolescence in the twin birth population is collected based on STBC, which can provide a solid data foundation for studying children’s chronic non-communicable diseases, psychological and behavioral disorders and other complex health problems caused by the combined effects of genetics and the environment.

ABSTRACT

ObjectiveTo introduce the basic design, development plan and objectives of a population-based birth cohort in Shanghai, and further present the main data and baseline characteristics of enrolled participants in the cohort, and to provide key information for reproductive health-related studies. MethodsThe Shanghai population-based birth cohort initiated on January 1, 2005, included newborns born in Shanghai every year and their parents, and collected information on reproductive health, reproductive treatment, birth characteristics, growth and development status, as well as the incidence, treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle. ResultsAs of October 2022, a total of 2 978 538 newborns and their parents were included in the cohort. Among them, 2 905 135 (97.54%) were naturally conceived (NC), and 73 403 (2.46%) were born through assisted reproductive technologies (ART). The average age of parents was (32.56±4.12) years old for females and (34.62±5.34) years old for males in the ART group, which was higher than (28.02±4.71) years and (30.07±5.54) years for parents in the NC group. Among parents, females and males aged 30 and above accounted for 77.12% and 85.08%, respectively, which were higher than that of parents (35.28% for females and 49.66% for males) in the NC group. Furthermore, the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males, which were higher than those in the NC group (49.98% and 50.91%, respectively). The multiple births rate in the ART group was 33.81%, which was higher than that in the NC group (1.88%). The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%, respectively, which was higher than that in the NC group (5.47% and 3.73%). ConclusionThe comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics, environment, reproductive treatment and other related factors on the health of offspring after birth.

ABSTRACT

Objective:To investigate the effect of cathodic transcranial direct current stimulation (ctDCS) combined with upper limb robot therapy (RT) on the rehabilitation of upper limb motor function in stroke patients.Methods:Forty patients with stroke hemiplegia who met the enrollment criteria were randomly divided into a pseudo-stimulation group ( n = 20) and a stimulation group ( n = 20). In addition to conventional treatment in both groups, ctDCS + RT was used in the stimulation group, and sham stimulation + RT was used in the sham-stimulation group. Treatment was performed 10 times, 5 times per week, for 30 minutes each time. Patients in both groups were evaluated before, during, and after treatment using the Brunnstrom Staging Scale, the Modified Barthel Index (MBI) scale, and the Modified Ashworth Scale (MAS), respectively. Results:Compared with the same group before treatment, there were statistically significant differences in Brunnstrom’s rating grade Ⅳ for upper limbs and hands in both groups during and after treatment (all P < 0.05). Compared with the same group during treatment, there were statistically significant differences in Brunnstrom’s rating grade Ⅳ for upper limbs and hands in both groups after treatment (all P < 0.05). MBI scores were higher in two groups during and after treatment compared to the same group before treatment (all P < 0.05). MBI scores were higher in two groups after treatment compared to the same group during treatment (all P < 0.05). The MBI scores after treatment in the stimulation group were higher than those in the pseudo-stimulation group ( P < 0.05). The MAS scores of elbow flexion grade 2 and extension grade 4 and shoulder flexion grade 2, extension grade 2, adduction grade 2, and abduction grade 2 were lower in both groups after treatment compared with the same group before treatment (all P < 0.05). Conclusions:Cathodic transcranial direct current stimulation combined with robotic therapy can effectively promote upper limb motor function rehabilitation in stroke patients and is superior to upper limb robotic therapy alone.

ABSTRACT

ObjectiveTo analyze the dynamic response relationship between urban development and mortality rate in Shanghai, and to predict the trend of mortality rate changes. MethodsBy analyzing the total mortality rate (TMR), gross domestic product (GDP) and socio-demographic index (SDI) in Shanghai from 1978 to 2017, a vector autoregressive (VAR) model was constructed to evaluate the impact of urban development on the mortality rate. ResultsThe fitted R2 of the VAR model was 0.92. The short-term effect of GDP on the improvement of death level was negative, while the long-term effect was positive, and the SDI was negative regardless of the short-term and long-term effects. By the tenth year, GDP and SDI contributed 10.61% and 27.25% to TMR changes, respectively. The model predicted that the mortality rate in Shanghai would be 9.17 per thousand by 2030. ConclusionLong-term economic growth can effectively promote a decline in population mortality. However, as the economy develops vigorously, the adverse effects of declining birth rates and population aging on population health during the era of high-level population development should not be ignored.

ABSTRACT

OBJECTIVE@#To assess the association of rs55829688 and rs75315904 polymorphisms of the lncRNA-GAS5 gene with susceptibility to systemic lupus erythematosus (SLE) in Guangxi population.@*METHODS@#Peripheral venous blood samples were collected from the SLE group and control group. Following extraction of genomic DNA, SNPscan and Sanger sequencing were carried out to determine the genotypes for the rs55829688 and rs75315904 loci of the lncRNA-GAS5 gene.@*RESULTS@#No difference was found between the two groups with regard to the genotypic frequencies for rs55829688 and rs75315904 (P > 0.05). However, the frequencies of C allele of rs55829688 between the two groups was significantly different (P < 0.05). In the SLE group, the frequencies of C allele and CT+CC genotype for rs55829688 among SLE patients with nephritis were significantly lower than those of SLE patients without nephritis (P < 0.05). In addition, haplotype analysis showed that the frequency of rs55829688 C/rs75315904 A allele in the SLE group was lower than that of the control group (P < 0.05).@*CONCLUSION@#In Guangxi population, the carrier status of rs55829688 C allele of the lncRNA-GAS5 gene may reduce the risk of SLE and its complicated nephritis, and the rs55829688 C/rs75315904 A haplotype may reduce the risk for SLE.

ABSTRACT

ObjectiveTo investigate the risk factors of fertility behaviors with preterm birth and low birth weight, and to develop a nomogram model to predict the occurrence of low birth weight. MethodsBirth registration information in Shanghai from 2010 to 2020 was collected, and ANOVA and Chi-square tests were used to compare the differences in reproductive behavior factors and newborn health status across time. The odds ratio (OR) value and 95%CI were calculated by a multi-classification logistic regression model to determine the association between reproductive behavior factors and preterm birth or low birth weight infants. A nomogram model was established based on logistic model and the area under the ROC curve was used to assess the effect of the model. ResultsThis analysis included 2 089 384 live newborns. The incidence of full-term low birth weight, preterm normal weight and preterm low birth weight in Shanghai was 0.94%, 2.48% and 2.01%, respectively. From 2010 to 2020, 40.00% women had a history of abortion, the proportion of women who gave birth at age ≥40 years old increased from 1.05% to 2.24%, the proportion of fathers aged ≥40 years increased from 4.79% to 7.48%, and the proportion of women with postgraduate or above increased from 4.81% to 11.74%. The incidence of preterm low birth weight in Shanghai showed an increasing trend over time. Logistic regression analysis showed that the risk of preterm low birth weight was lower in female than in male infants (OR=0.97, 95%CI: 0.95‒0.98), and the risk of full-term low birth weight was higher than in male infants (OR=1.85, 95%CI: 1.80‒1.90). The risk of preterm birth and low birth weight was lower for couples of childbearing age with higher education. The risk of preterm low birth weight in newborns tended to increase with maternal age at childbirth >30 years, paternal age ≥40 years, and the number of abortions >2 times. Mother <25 or >35 years, father aged 30‒34 years, and the number of abortions >3 times were the risk factors of full-term low birth weight infants. ConclusionCouples of childbearing age who choose to have children at too high or too low age may increase the risk of preterm birth or low birth weight, so it is necessary to strengthen population awareness and promote age-appropriate childbirth. Multiple abortions are also associated with preterm birth and low birth weight, and it is advisable to popularize the scientific knowledge of contraception and birth control to reduce unnecessary abortions. The nomogram in the study can visualize the risk of full-term and low birth weight infant at different levels of factors, which can assist couples preparing for pregnancy in making decisions about the timing of childbirth and understanding the level of risk.

ABSTRACT

Objective To establish a fluorescent assay for rapid detection of Plasmodium falciparum based on recombinaseaided amplification (RAA) and CRISPR-Cas12a system,and to preliminarily evaluate the diagnostic efficiency of this system.. Methods The 18S ribosomal RNA (rRNA) gene of P. falciparum was selected as the target sequence, and three pairs of RAA primers and CRISPR-derived RNA (crRNA) were designed and synthesized. The optimal combination of RAA primers and crRNA was screened and the reaction conditions of the system were optimized to create a fluorescent RAA/CRISPR-Cas12a system. The plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 was generated, and diluted into concentrations of 1 000, 100, 10, 1 copy/μL for the fluorescent RAA/CRISPR-Cas12a assay, and its sensitivity was evaluated. The genomic DNA from P. vivax, P. malariae, P. ovum, hepatitis B virus, human immunodeficiency virus and Treponema pallidum was employed as templates for the fluorescent RAA/CRISPR-Cas12a assay, and its specificity was evaluated. Fifty malaria clinical samples were subjected to the fluorescent RAA/CRISPR-Cas12a assay and nested PCR assay, and the consistency between two assays was compared. In addition, P. falciparum strain 3D7 was cultured in vitro. Then, the culture was diluted into blood samples with parasite densities of 1 000, 500, 200, 50, 10 parasites/μL with healthy volunteers’ O-positive red blood cells for the RAA/CRISPR-Cas12a assay, and the detection efficiency was tested. Results The Pf-F3/Pf-R3/crRNA2 combination, 2.5 μL as the addition amount of B buffer, 40 min as the RAA reaction time, 37 °C as the reaction temperature of the CRISPR-Cas12a system were employed to establish the fluorescent RAA/CRISPR-Cas12a system. Such a system was effective to detect the plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 at a concentration of 1 copy/μL, and presented fluorescent signals for detection of P. falciparum, but failed to detect P. ovum, P. malariae, P. vivax, T. pallidum, hepatitis B virus or human immunodeficiency virus. The fluorescent RAA/CRISPR-Cas12a system and nested PCR assay showed completely consistent results for detection of 50 malaria clinical samples (kappa = 1.0, P < 0.001). Following 6-day in vitro culture of the P. falciparum strain 3D7, 10 mL cultures were generated and the fluorescent RAA/CRISPR-Cas12a system showed the minimal detection limit of 50 parasites/μL. Conclusion The fluorescent RAA/CRISPR-Cas12a system is rapid, sensitive and specific for detection of P. falciparum, which shows promising value for rapid detection and risk monitoring of P. falciparum.

ABSTRACT

ObjectiveTo investigate the characteristics of gender difference and the trend of the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018, and to provide the basis for formulating relative intervention measures before and after senile dementia from an public-health view. MethodsBased on the collected data of death registration, focused on the senile dementia disease codes F03,G30.0,G30.1,G30.8,G30.9 according to The International Classification of Diseases 10th revision (ICD-10). We analyzed the characteristics of gender difference in the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018. According to ASR, we calculated the standardized mortality rate of senile dementia, and used the chi-square test to compare the difference between the gender mortality rates. The trend and the turning point of the mortality rate of senile dementia were determined by linear regression analysis by Join-point. ResultsThe crude mortality rate of senile dementia in the registered population in Shanghai from year 2002 to 2018 was 5.46/105, 3.50/105 in males and 7.43/105 in females. The standardized mortality rate of senile dementia was 2.61/105, 1.67/105 in males and 3.56/105 in females. The trend of the standardized mortality rate of senile dementia in 17 years decreased [APC=-5.5(-6.5,-4.5)%,P<0.01]. The trend of the standardized mortality rate of senile dementia decreased in both males [APC=-4.9(-6.2,-3.6)%,P<0.01] and females [APC=-5.9(-6.9,-4.9)%,P<0.01]. The trend of the gender difference decreased [APC=-6.8(-8.2,-5.3)%,P<0.01]. The mortality rate of senile dementia was higher in females than in males [(χ2=33.63,P<0.01)]. ConclusionThe mortality rate of senile dementia in females is higher than in males in Shanghai, though the trend of the gender difference decreased. This gender difference is worth of attention.

ABSTRACT

Objective:To analyze the clinical diagnosis, treatment ,and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University(Qingdao) from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.

ABSTRACT

Transcranial direct current stimulation (tDCS) has become a new method of post-stroke rehabilitation treatment and is gradually accepted by people. However, the neurophysiological mechanism of tDCS in the treatment of stroke still needs further study. In this study, we recruited 30 stroke patients with damage to the left side of the brain and randomly divided them into a real tDCS group (15 cases) and a sham tDCS group (15 cases). The resting EEG signals of the two groups of subjects before and after stimulation were collected, then the difference of power spectral density was analyzed and compared in the band of delta, theta, alpha and beta, and the delta/alpha power ratio (DAR) was calculated. The results showed that after real tDCS, delta band energy decreased significantly in the left temporal lobes, and the difference was statistically significant ( P < 0.05); alpha band energy enhanced significantly in the occipital lobes, and the difference was statistically significant ( P < 0.05); the difference of theta and beta band energy was not statistically significant in the whole brain region ( P > 0.05). Furthermore, the difference of delta, theta, alpha and beta band energy was not statistically significant after sham tDCS ( P > 0.05). On the other hand, the DAR value of stroke patients decreased significantly after real tDCS, and the difference was statistically significant ( P < 0.05), and there was no significant difference in sham tDCS ( P > 0.05). This study reveals to a certain extent the neurophysiological mechanism of tDCS in the treatment of stroke.

ABSTRACT

ObjectiveTo analyze the effect of frailty status on the risk of mortality in a community-based population aged 45 years and above in Shanghai with different characteristics, and to provide further basis for population-based interventions for frailty and prevention of adverse outcomes. MethodsData were derived from baseline data from the Shanghai prospective study on AGEing and adult health (2009-2010) and cohort follow-up of causes of death up to October 30, 2021. Frailty index (FI) scores were constructed from 40 variables. Those with frailty index FI≥0.2 were judged to be in a frail state, and a multifactorial Cox regression model was used to calculate the hazard ratio (HR) to evaluate the effect of frailty status on the risk of death in different age groups by gender. Socioeconomic characteristics (age, residence, marital status, education and family economic level, etc.) and health-related behaviors (smoking, alcohol consumption, fruit and vegetable intake, social participation, etc.) were included as control variables. ResultsThe study included 7 978 subjects, 777 (9.7%) of whom were in a frail state. After (11.3±1.8) years of follow-up, 1 043 (13.1%) individuals were dead, including 214 (27.5%) who were frail. The results of the multifactorial Cox regression analysis showed that the effect of frailty on the risk of death in each subgroup was in descending order of men in the middle-aged group (45‒ years) (HR=2.92, 95%CI: 1.38-6.19), women in the low-aged elderly group (60‒ years) (HR=1.68, 95% CI: 1.08-2.60), and women in the old-aged elderly group (≥75 years and older) (HR=1.59, 95%CI: 1.22‒2.06). ConclusionFrailty is associated with the risk of death, and we should focus on the frailty status of men aged 45~59 years and women aged 60 years and above. Early screening and assessment of frailty status and taking appropriate preventive interventions may reduce the occurrence of adverse outcomes and premature death.

ABSTRACT

BACKGROUND@#Little was known about the association among time in range (TIR), time above range (TAR), time below range (TBR), and cancer mortality among patients with type 2 diabetes. We aimed to investigate the association among TIR, TAR, TBR, and the risk of cancer mortality among patients with type 2 diabetes.@*METHODS@#A total of 6225 patients with type 2 diabetes were prospectively recruited in Shanghai, China. TIR was measured with continuous glucose monitoring at baseline and was defined as the average percentage of time in the target glucose range during a 24 h period. Cox proportion hazard regression analysis was used to determine the association between TIR and the risk of cancer mortality.@*RESULTS@#During a mean follow-up of 7.10 years, we confirmed 237 death events related to cancer. The multivariable-adjusted hazard ratio (HR) for cancer mortality was 1.32 (95% confidence interval [CI]: 1.01-1.75) in patients with TIR ≤70% compared with those with TIR >70%. When TIR was considered as a continuous variable, the multivariable-adjusted HR for cancer mortality associated with each 10% decrease in TIR was 1.07 (95% CI: 1.02-1.14). In the site-specific analysis, a significant association between TIR as a continuous variable and the risk of hepatocellular cancer was found (HR: 1.24; 95% CI: 1.09-1.41). However, no relationship between hemoglobin A1c and cancer mortality was observed (HR: 1.04; 95% CI: 0.97-1.10).@*CONCLUSIONS@#The present study found an inverse association of TIR with the risk of cancer mortality among patients with type 2 diabetes. New evidence of TIR was added into the clinical practice that TIR may be an optimal target of glycemic control among patients with type 2 diabetes.

ABSTRACT

Objective:To investigate the effect of transcranial direct current stimulation (tDCS) on the behavior and the mismatch negativity (MMN) component of the auditory evoked potential of autistic children.Methods:Thirty-four autistic children were randomly divided into an anode stimulation group ( n=19) and a pseudo-stimulation group ( n=16). Both groups were given one hour of routine rehabilitation five times a week for 4 weeks, while the anode stimulation group was additionally provided with 20 minutes of tDCS 3 times a week. Before and after the treatment, both groups′ behavior was evaluated by using autism behavior checklist (ABC) as well as any changes in MMN of the auditory evoked EEG signals. Results:There were no significant differences between the two groups in any of the measurements before the treatment. Afterwards behavior had improved significantly in both groups, with significantly greater improvement in the stimulated group. In the stimulated group the average MMN amplitude had increased significantly and the average latency had decreased significantly. However, no such significant changes were observed in the pseudo-stimulation group. There was a significant linear correlation between the changes in the incubation period of MMN components and the improvements in ABC, vestibular functioning, tactile defense and proprioception.Conclusion:Anodal tDCS combined with conventional rehabilitation therapy can effectively increase the MMN amplitude and shorten the latency in autistic children, improving their brain function.

ABSTRACT

Transcranial direct current stimulation (tDCS) is an emerging non-invasive brain stimulation technique. However, the rehabilitation effect of tDCS on stroke disease is unclear. In this paper, based on electroencephalogram (EEG) and complex network analysis methods, the effect of tDCS on brain function network of stroke patients during rehabilitation was investigated. The resting state EEG signals of 31 stroke rehabilitation patients were collected and divided into stimulation group (16 cases) and control group (15 cases). The Pearson correlation coefficients were calculated between the channels, brain functional network of two groups were constructed before and after stimulation, and five characteristic parameters were analyzed and compared such as node degree, clustering coefficient, characteristic path length, global efficiency, and small world attribute. The results showed that node degree, clustering coefficient, global efficiency, and small world attributes of brain functional network in the tDCS group were significantly increased, characteristic path length was significantly reduced, and the difference was statistically significant (

ABSTRACT

Objective:To compare the efficacy of augmentation suture and direct suture in treatment of acute Achilles tendon ruptures so as to provide evidences for the selection of surgical methods.Methods:A systematic search was conducted in PubMed, Web of Science, EMBASE, CNKI and Wanfang database for studies of augmentation suture versus direct suture of acute Achilles tendon ruptures. Literatures were retrieved from January 1990 to January 2019. Literatures were screened according to the pre-set inclusion and exclusion criteria, and the rating of included literature was strictly evaluated by the Cochrane System Evaluation Manual and Newcastle-Ottawa scale (NOS). The relevant data were analyzed using RevMan 5.3 to compare patient satisfaction, rerupture rate, infection rate, ankle's range of motion and other complications (postoperative calf atrophy, plantar flexion, plantar flexion strength).Results:Eight articles involving 558 patients were identified including 273 patients in augmentation suture group and 285 patients in direct suture group. There were no significant differences between two groups in aspects of patient satisfaction ( OR=1.00, 95% CI 0.54-1.84, P>0.05), rerupture rate ( OR=0.75, 95% CI 0.34-1.66, P>0.05), infection rate ( OR=1.73, 95% CI 0.76-3.94, P>0.05), ankle's range of motion ( OR=0.97, 95% CI 0.33-2.87, P>0.05) and other complications rate ( OR=1.93, 95% CI 0.91-4.09, P>0.05). Meantime, the two groups showed similar effect on postoperative calf atrophy and average isokinetic calf muscle strength ( P>0.05). There was a significant difference in plantar flexion of injured limbs after augmentation suture( P<0.05). Conclusion:Compared with direct suture, augmentation suture cannot improve patient satisfaction or reduce complication rate in repair of acute Achilles tendon ruptures.

ABSTRACT

OBJECTIVE@#To analyze the incidence, genotype and hematological feature of hemoglobin H (HbH) disease in West Guangxi region.@*METHODS@#A total of 1246 patients diagnosed with HbH disease from January 2013 to December 2018 in our hospital were enrolled. Red blood cell parameters, hemoglobin electrophoresis, Gap-polymerase china reaction (Gap-PCR) and polymerase chain reaction-reverse dot blot (PCR-RDB) techniques were used to detect the 6 common α-thalassemia mutations and 17 common β-thalassemia mutations. The results were compared with those of other regions.@*RESULTS@#The detection rate for HbH disease was 5.66%. Among the 1246 patients, 614 (49.28%) had deletion-type HbH disease, including -α @*CONCLUSION@#The prevalence of HbH disease is high in West Guangxi region, and the main genotypeis non-deletion. α

ABSTRACT

Objective@#To investigate the characteristics of polymorphism distribution at the functional insertion/deletion locus rs145204276I/D in the promoter region of LncRNA GAS5 (growth-arrest specific transcript 5) gene in population of Guangxi district, and analyze the differences of polymorphism distribution of rs145204276I/D in the populations between Guangxi and other regions. @*Methods@#SNPscan high-throughput sequencing technique was used to detect rs145204276I/D locus in genotype of GAS5 gene of 289 subjects from Guangxi district, and the distribution frequencies of genotypes and alleles between different genders were analyzed. The differences of polymorphism distribution were compared with those in the database from the population of European (EUR), Japanese in Tokyo (JPT), South Asian (SAS), Admixed American (AMR), African (AFR), Chinese Han in Beijing (CHB), Nanjing, Jilin, Chongqing and Kunming which were published by 1000 genome project or reported in literatures. @*Results@#The frequencies of I/I, I/D and D/D genotypes of rs145204276I/D in GAS5 were 48.4%, 43.6% and 8.0%, respectively. The frequencies of I and D alleles were 70.2% and 29.8%, respectively. No significant difference of genotype and allele frequencies of rs145204276I/D was observed between different genders in Guangxi population ( P >0.05). The genotype and allele frequencies of rs145204276I/D in Guangxi population were significantly different from JPT, EUR, AFR, SAS and AMR populations ( P <0.05), but were not significantly different from those of Chinese Han population in Beijing, Nanjing, Jilin, Chongqing and Kunming ( P >0.05). @*Conclusion@#The distribution of LncRNA GAS5 gene rs145204276I/D polymorphism in Guangxi population was not different between men and women, and the polymorphism of LncRNA GAS5 gene was different from those of other regions in the world.

ABSTRACT

OBJECTIVE@#Few studies investigating associations between fine particulate air pollution and hemorrhagic stroke have considered subtypes. Additionally, less is known about the modification of such association by factors measured at the individual level. We aimed to investigate the risk of fatal intracerebral hemorrhage (ICH) incidence in case of PM (particles ≤ 2.5 μm in aerodynamic diameter) exposure.@*METHODS@#Data on incidence of fatal ICH from 1 June 2012 to 31 May 2014 were extracted from the acute stroke mortality database in Shanghai Municipal Center for Disease Control and Prevention (SCDC). We used the time-stratified case-crossover approach to assess the association between daily concentrations of PM and fatal ICH incidence in Shanghai, China.@*RESULTS@#A total of 5286 fatal ICH cases occurred during our study period. The averaged concentration of PM was 77.45 μg/m. The incidence of fatal ICH was significantly associated with PM concentration. Substantial differences were observed among subjects with diabetes compared with those without; following the increase of PM in lag2, the OR (95% CI) for subjects with diabetes was 1.26 (1.09-1.46) versus 1.05 (0.98-1.12) for those without. We did not find evidence of effect modification by hypertension and cigarette smoking.@*CONCLUSIONS@#Fatal ICH incidence was associated with PM exposure. Our results also suggested that diabetes may increase the risk for ICH incidence in relation to PM.

ABSTRACT

Objective To evaluate the effect of isokinetic muscle training combined with semiconductor laser on acute knee osteoarthritis (KOA). Methods Ninety-eight KOA patients were randomly divided into 4 groups. All patients were treated with conventional rehabilitation treatment and nursing. Based on that treatment, the group 1 received semiconductor laser irradiation, the group 2 received isokinetic muscle training, and the group 3 received laser irradiation combined with isokinetic muscle training. All patients were assessed with WOMAC osteoarthritis rating scale and affected knee extensor and flexor muscles strength measurement including peak torque, peak work, average power, average work and flex/extend before and 4 weeks after the treatment. Results All of the four treatments can significantly alleviate the condition of acute KOA patients and improve the muscle condition around the ipsilateral knee joint. The isokinetic muscle training improves the knee function of KOA patients better than the laser irradiation treatment. Isokinetic strength training combined with laser irradiation can get the most significant improvement of knee joint pain, stiffness, dysfunction, muscle strength of flexors and extensors in KOA patients. Conclusions The combination of isokinetic muscle training and semiconductor laser irradiation has a significant effect on relieving pain, reducing the stiffness, improving the function of knee of the patients with KOA in the acute phase and improving the muscle strength of the affected lower extremities. That methad is superior to drug therapy, physical therapy, or exercise alone, and is better to solve the problem of relieving symptoms and enhancing function simultaneously.
