OBJECTIVETo identify the clinical phenotype and gene mutation in two kindreds with type I inherited antithrombin (AT) deficiency.

METHODSThe coagulation and anticoagulation testing and thrombophilia screening were used for phenotypic diagnosis and immunonephelometry and chromogenic assay for plasma level of AT antigen (AT:Ag) and AT activity (AT:A), respectively. All of the seven exons and intron-exon boundaries and untranslation regions of AT gene were amplified by PCR, and the PCR products analysis was by direct sequencing. The corresponding gene sites of the two family members and healthy individuals were detected according to the gene mutation sites.

RESULTSThe plasma levels of AT:Ag of proband 1 and proband 2 were 126 mg/L and 117 mg/L, and AT:A was 49% and 48%, respectively. Heterozygotic deletion of 3239-3240delCT in proband 1 and nonsense mutation 3206A-->T (K70Stop) in proband 2 were rchaacterized in exon 2 of AT gene. And some of their family members were also detected with the heterozygotic gene mutation.

CONCLUSIONType I inherited antithrombin deficiency of the two probands were caused by AT gene mutation 3239-3240delCT and 3206A-->T (K70Stop).

BACKGROUNDThere are more than 300 genetic loci that have been found to be related to hereditary hearing impairment (HHI), including 92 causative genes for nonsyndromic hearing loss, among which 34 genes are related to autosomal dominant nonsyndromic HHI (ADNSHHI). Traditional linkage analysis and candidate gene sequencing are not effective at detecting the ADNSHHI, especially for the unconditional families that may have more than one pathogenic cause. This study identified two disease-causing genes TJP2 and GJB2 in a Chinese family with unconditional ADNSHHI.

METHODSTo decipher the genetic code of a Chinese family (family 686) with ADNSHHI, different gene screening techniques have been performed, including linkage analysis, candidate genes screening, high-throughput sequencing and Sanger sequencing. These techniques were done on samples obtained from this family over a period of 10 years.

RESULTSWe identified a pathogenic missense mutation, c. 2081G>A (p.G694E), in TJP2, a gene that plays a crucial role in apoptosis and age-related hearing loss (ARHL). The mutation was co-segregated in this pedigree in all, but not in the two patients who presented with different phenotypes from the other affected family members. In one of the two patients, we confirmed that the compound heterozygosity for p.Y136* and p.G45E in the GJB2 gene may account for the phenotype shown in this patient.

CONCLUSIONSWe identified the co-occurrence of two genetic causes in family 686. The possible disease-causing missense mutation of TJP2 in family 686 presents an opportunity for further investigation into ARHL. It is necessary to combine various genes screening methods, especially for some unconventional cases.

OBJECTIVETo investigate the prevalence, current treatment, and clinical characteristics of asthma, as well as the risk factors for this disease, among children aged 0-14 years in 2010 in urban Zhongshan, China.

METHODSA total of 10 336 children aged 0-14 years were selected from urban Zhongshan by cluster random sampling. The Third National Childhood Asthma Epidemiological Questionnaire 2010 was used to analyze the prevalence, current treatment, and clinical characteristics of childhood asthma, as well as the risk factors for this disease.

RESULTSAsthma was diagnosed in 179 cases (1.73%). The prevalence of asthma in male children was significantly higher than that in female children (2.25% vs 1.16%; P<0.01). Of the 179 patients, severe attacks were common in 104 cases (58.1%), 110 cases (61.5%) had slow onset, 102 cases (57.0%) had gradually relieved conditions, 61 cases (34.1%) suffered from asthma during seasonal transition, and 150 cases (83.8%) developed asthma due to respiratory tract infection. Among all asthmatic children, 71.5% had been treated with inhaled corticosteroids, and 71.5% had been treated with bronchodilator. The multivariate logistic regression analysis showed that a history of penicillin allergy, a family history of allergy, food allergy, eczema, allergic rhinitis, cesarean delivery, family mould, and perinatal passive smoking were independent risk factors for childhood asthma.

CONCLUSIONSThe prevalence of childhood asthma in urban Zhongshan is on a high level, and is associated with gender. The treatment of asthma has been standardized, but still needs further improvement. The onset of asthma attack is influenced by various factors.

To systematically evaluate the clinical efficacy and safety of modified Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly, and provide evidence-based reference for the clinical application of this prescription. Randomized controlled trials of Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly were collected by searching PubMed, EMbase, Cochrane Library, CNKI, China Biomedical Literature database, VIP database and WanFang database. Outcome indicators included clinical effective rate, inflammation index, symptom improvement time, chest radiograph improvement time, hospitalization time and adverse reactions. RevMan 5.3 and Stata/IC 15.1 software were used for Meta-analysis; TSA 0.9.5.10 Beta software was used for trial sequential analysis, and GRADE profiler 3.6 was used for grade evidence quality evaluation. Thirteen studies were included finally, including 1 058 patients, 536 patients in the experimental group and 522 patients in the control group.Meta-analysis showed that, the clinical effective rate of the experimental group was significantly higher than that of the control group(RR=1.16, 95%CI[1.10, 1.21], P<0.000 01); fever time(MD=-1.32, 95%CI[-1.93,-0.71], P<0.000 1), cough time(MD=-1.95, 95%CI[-2.69,-1.21), P<0.000 01), time to rale disappearance(MD=-1.55, 95%CI[-2.37,-0.73], P=0.000 2), time to chest radiograph improvement(MD=-1.72, 95%CI[-2.98,-0.46], P=0.007), and hospitalization time(MD=-3.16, 95%CI[-4.58,-1.74], P<0.000 01) in the experimental group were significantly shorter than those in the control group. The improvement in CRP(WMD=-3.44,95%CI[-4.50,-2.38],P<0.001), WBC(WMD=-2.04,95%CI[-3.31,-0.78],P<0.01), IL-6(WMD=-4.27,95%CI[-4.62,-3.92],P<0.001), and TNF-α(WMD=-0.47,95%CI[-0.55,-0.39], P<0.001) of the experimental group was significantly better than that of the control group. There was no significant difference in PCT improvement between the two groups(WMD=-0.63, 95%CI[-1.65, 0.40], P=0.23). No serious adverse reactions occurred in both groups. Sequential analysis of the trial showed that in the studies with cumulative inclusion of clinical effective rate, the data passed the traditional threshold and TSA threshold, further confirming its clinical efficacy. GRADE evaluation showed that the evidence level was low to extremely low. Western medicine treatment combined with Qingjin Huatan Decoction may improve clinical efficiency in the treatment of community-acquired pneumonia in the elderly, improve clinical symptoms faster, reduce CRP, WBC and other inflammatory indicators, and shorten hospital stay. The level of evidence obtained in this study is low, which needs to be further verified by high-quality multi-center, randomized controlled trials.

Objective To analysis the effects on the growth of rats by repeated restraint in dermal exposure test. Methods SD rats in the restraint group was bound for 6 hours per day for 91 days according the way by dermal exposure, while SD rats in the control group didn't receive the treatment. Clinical signs, body weight and food consumption changes were observed for 91 days. When the study was terminated, hematology, clinical biochemistry, urinalyses, gross necropsy, and histopathology were carried out. Statistical methods such as the generalized estimating equation were used to compare the differences between two groups. Results The statistical results of generalized estimating equation showed that there was an interaction between the group and test time for male and female rats in body weight changes (P<0.05), and the body weight of male rats in the restraint group was lower than the control group (P<0.05) . Further analysis showed that for male rats there was significant difference between groups since the forth week (P<0.05), and the interaction was found between groups and test time (P<0.05) . For female rats, the interaction was found since the eighth week between the group and test time (P <0.05) .There was no significant differences in other parameters between two groups (P>0.05) . Conclusion Repeated restraint during dermal exposure affected the body weight gain of rats, and the sensitivity of male rats was higher than that of female rats.

To investigate the existence of tick-borne pathogens infection of rodents at the border of China and the Demo-cratic People's Republic of Korea(DPRK).PCR was used to detect the spotted fever group rickettsiae(SFGR)ompA gene,Ehrlichia chaffeensis(Ec)and Anaplasma phagocytophilum(Ap)16S rRNA,Candidatus Neoehrlichia mikurensis(CNm)groEL gene,Bartonella(Ba)rpoB gene,and Francisella tularensis(Ft)fopA gene in rodents samples collected from Ji'an of Jilin province and Kuandian of Liaoning Province.The positivity rates of 132 wild rats spleen samples,SFGR,Ec,Ap,CNm,Ba,and Ft were 9.85％,12.88％,5.30％,3.79％,51.52％,and 6.06％,respectively,with statistical differences in in-fection rates(x2=149.236,P=0.000).The infection rate of Ba was the highest in wild rats in this area.There was no signifi-cant difference in the infection rate of SFGR,Ec,Ap,CNm,and Ft among different rats species,but there were significant differences in the infection rate of Ba(x2=13.36,P=0.010).The infection rate of Apodemus agrarius was the highest.A-mong 132 wild rats specimens,the coinfection rate of the two pathogens was 15.9％(21/132),with Ba as the main species(15/132),and two cases of coinfection with three pathogens were detected.The infection of six tick-borne pathogens is common in wild rats at the China/DPRK border.Co-infection of two or three pathogens indicates a risk of multiple tick-borne pathogens and mixed natural foci of multiple tick-borne infec-tious diseases.

ObjectiveTo investigate the effect of modified Renshen Wumeitang（MRWT） on the related regulatory factors of the γ-aminobutyric acid （GABA） signaling pathway in colon tissues of rats with diarrhea， and reveal the mechanism of MRWT in invigorating Qi， generating fluid， and checking diarrhea. MethodForty-eight SD immature rats were randomly divided into a blank group （n=12） and an experimental group （n=36）. The diarrhea model was induced in the experimental group by Sennae Folium combined with overstrain and improper diet for 14 days. Subsequently， the model rats were randomly divided into a model group （normal saline， 20 mL·kg^-1）， a western medicine group （Medilac-Vita， 0.7 g·kg^-1）， and a Chinese medicine group （MRWT， 35 g·kg^-1）， with 12 rats in each group. The rats in the blank group received normal saline at 20 mL·kg^-1， and those in the other groups were treated correspondingly， once a day for 7 days. The general condition， loose stool rate， and diarrhea index of the rats were observed daily. Immunohistochemistry was used to detect the optical density expression of GABA protein in the colon of rats. The content of phosphatidylinositol-3 kinase （PI3K）， protein kinase B2 （Akt2）， phosphorylated Akt （p-Akt）， and interleukin-1β （IL-1β） was determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expression levels of PI3K， Akt2， and GABA type A receptor subunit β₂ （GABRB2） in the colon of rats were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with the blank group， the model group showed worsened general condition， The difference was not statistically significant of loose stool rate and diarrhea index， increased expression of GABA protein （P<0.05）， elevated expression of PI3K， Akt2， p-Akt， and IL-1β （P<0.05， P<0.01）， and up-regulated PI3K， Akt2， and GABRB2 mRNA and protein expression （P<0.01）. Compared with the model group， the western medicine group and the Chinese medicine group showed the improved general condition， decreased loose stool rate and diarrhea index （P<0.01）， and decreased content of PI3K， Akt2， p-Akt， and IL-1β （P<0.05）. The Chinese medicine group displayed decreased mRNA expression of PI3K， Akt2， and GABRB2 （P<0.05， P<0.01） and down-regulated protein expression of GABA， PI3K， and GABRB2 （P<0.05， P<0.01）. The western medicine group exhibited down-regulated mRNA expression of PI3K，Akt2，and protein of PI3K （P<0.05）. ConclusionMRWT can regulate the GABA signaling pathway， reduce Cl^- flow in intestinal epithelial cells to the intestinal lumen， and improve the imbalance of colonic fluid metabolism in the colon of diarrhea rats， thereby exerting its effects of invigorating qi， generating fluid， and checking diarrhea.

BACKGROUNDHypoparathyroidism-deafness-renal dysplasia (HDR) syndrome is an autosomal dominant disorder primarily caused by haploinsufficiency of GATA binding protein 3 (GATA3) gene mutations, and hearing loss is the most frequent phenotypic feature. This study aimed at identifying the causative gene mutation for a three-generation Chinese family with HDR syndrome and analyzing auditory phenotypes in all familial HDR syndrome cases.

METHODSThree affected family members underwent otologic examinations, biochemistry tests, and other clinical evaluations. Targeted genes capture combining next-generation sequencing was performed within the family. Sanger sequencing was used to confirm the causative mutation. The auditory phenotypes of all reported familial HDR syndrome cases analyzed were provided.

RESULTSIn Chinese family 7121, a heterozygous nonsense mutation c.826C>T (p.R276*) was identified in GATA3. All the three affected members suffered from sensorineural deafness and hypocalcemia; however, renal dysplasia only appeared in the youngest patient. Furthermore, an overview of thirty HDR syndrome families with corresponding GATA3 mutations revealed that hearing impairment occurred earlier in the younger generation in at least nine familial cases (30%) and two thirds of them were found to carry premature stop mutations.

CONCLUSIONSThis study highlights the phenotypic heterogeneity of HDR and points to a possible genetic anticipation in patients with HDR, which needs to be further investigated.
