ObjectiveTo comprehensively evaluate the curative effect ofTCM reating type 2 diabetes with three type dialectical therapy by Fuzzy Mathematics.Methods261 cases of 2 type diabetes were divided into three groups by syndrome differentiation,as follows:type of heat with yin deficiency,type of deficiency of both qi and yin,and type of deficiency of both yin and yang,and received corresponding therapies.The course of treatment was 24 weeks,in the first 12 weeks (period 1),on the basis of western medicine treatment,patients of the three groups were respectively treated by qingrungranules,ziyigranule and shuangtiaogranules.In the next 12 weeks (period 2),all patients were only treated by western medicine.The value of FBG,P2BG,HbAlc,TC,TG,BMI of the two periods were comprehensively evaluated by the methods of fuzzy mathematics.ResultsAt the end of period 1,the total effective rate of the type of heat with yin deficiency was 91.38％,the type of deficiency of both qi and yin was 87.16％,and the type of deficiency of both yin and yang was 83.34％; while at the end of period 2,the total effective rate of the three types was 59.18％,48.65％a nd32.65％ respectively.ConclusionThe effective rate was obviously improved in period 1; while in period 2,the effective rate was decreased.

Objective To describe the clinical characteristics of a patient with Gitelman syndrome,and to identify the associated SLC12A3 gene mutations.Methods A suspected case of teenager-onset Gitelman syndrome was observed in our hospital.It was further confirmed by clinical manifestations and auxiliary examination.In addition,direct sequencing for the exons of SLC12A3 gene and CLCNKB gene region was conducted to identify the probable disease-associated mutations.Results The case showed characteristics of hypokalemia,hypomagnesemia,and low level of urinary calcium and onset by age of 18.By excluding the possibilities of long-term use of thiazide diuretics,laxatives,chronic vomiting and diarrhea,he was finally diagnosed as a case of Gitelman syndrome.Furthermore,by Sanger direct sequencing,2 coding variations were identified in SLC12A3 gene region,including T304M and L488P.L488P was a new heterozygous mutation.Conclusion Detection of SLC12A3 gene mutation could facilitate the diagnosis of Gitelman syndrome and improve prognosis.

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.

OBJECTIVETo identify the mutations in the gap junction protein alpha3/alpha8 gene (GJA3 or GJA8) in the Chinese family with autosomal dominant congenital cataract (ADCC).

METHODSAll subjects(5 family members and 100 unrelated control individuals)were undergone comprehensive ophthalmic examination, and genomic DNA was extracted from peripheral blood (5 mL). The exons and flanking introns of GJA3/GJA8 genes were amplified by polymerase chain reaction (PCR). Purified PCR products were then sequenced directly for screening disease-causing mutations.

RESULTSUpon bidirectional sequence analysis, a G-->A transition at nucleotide 138 (c.138G>A)in exon 2 of GJA8 was found, resulting in synonymous mutation of glycine (GGG) to glycine (GGA). An additional G-->T transvertion at nucleotide 139 (c.139G>T) in exon 2 of GJA8, resulting in a missense mutation of asparagines (GAU) to tyrosine (UAU) at codon 47 (D47Y). These two alterations were not seen in all unaffected members and 100 unrelated control individuals. Bioinformatic analyses also showed that a highly conserved region was located at Asp47. Meanwhile no sequence variations for GJA3 were detected from the 3 affected members.

CONCLUSIONA novel disease-causing mutation (D47Y) of GJA8 gene in a Chinese family with ADCC is reported.

Abstract: The demand for reliable toxicological data of chemicals runs through every link of occupational health work. The prevention of occupational diseases involves high requirements for the standardization of chemical toxicity assessment in occupational health institutions. Good laboratory practice (GLP) emphasizes the integrity of the test process to trace and supervise the whole process of the test, which is conducive to the standardization of chemical toxicity identification. Therefore, the standardized construction of GLP laboratories is an important starting point for occupational health institutions to carry out chemical toxicity identification. In the construction and management process of GLP laboratories for chemical toxicity identification, occupational health institutions need to build a sound organization and operation system, carry out systematic training and assessment of personnel, establish standard operating norms and emphasize their importance, strengthen the management of facility environment and laboratory, pay attention to quality control and process supervision, and constantly improve their own ability level. To actively adapt to social development and market demand, to provide strong support for occupational health work.

OBJECTIVE: To detect the serum level of a novel autoantibody, anti-tubulin-α-1C, in patients with systemic sclerosis (SSc) and to investigate its clinical significance. METHODS: Anti-tubulin-α-1C antibody levels were determined by enzyme-linked immunosorbent assay (ELISA) in 62 patients with SSc, 38 systemic lupus erythematosus (SLE), 24 primary Sjögren's syndrome (pSS) patients, and 30 healthy controls (HCs). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), immunoglobulin A(IgA), immunoglobulin M (IgM), immunoglobulin G (IgG), C3, C4, rheumatoid factor (RF), antinuclear antibody(ANA), anti-centromere antibodies(ACA), anticardiolipin (aCL), anti-dsDNA antibody, anti-Sm antibody, anti-RNP antibody, anti-Scl-70 antibody, anti-Ro52 antibody, anti-SSA antibody, anti-SSB antibody, centromere protein A(CENP-A), centromere protein B (CENP-B) were measured by standard laboratory techniques. Raynaud's phenomenon and modified Rodnan skin score(MRSS) were recorded to evaluate the disease status of SSc. Independent sample t test, Chi square test, Mann-Whitney U test, Spearman rank correlation were used for statistical analyses. RESULTS: The serum anti-tubulin-α-1C antibody concentration in SSc group was 81.24±34.38, the serum anti-tubulin-α-1C antibody concentration in SLE group was 87.84±38.52, the serum anti-tubulin-α-1C antibody concentration in pSS group was 59.79±25.24, and the serum anti-tubulin-α-1C antibody concentration in healthy group was 39.37±18.7. Multivariate analysis revealed that anti-tubulin-α-1C antibody levels were significantly increased in the SSc and SLE patients. The expression level of anti-tubulin-α-1C antibody in SSc was higher compared with the pSS group and the health control group (P < 0.01). Further analysis demonstrated that the elevated anti-tubulin-α-1C antibody were correlated with the SSc inflammation and disease activity markers ESR(r=0.313, P=0.019), The levels of anti-tubulin-α-1C antibody were also significantly correlated with MRSS(r=0.636, P < 0.01). The best cut-off value for the diagnose of SSc was 76.77 as mean+2SD value. The proportion of Raynaud's phenomenon was higher in the group of anti-tubulin-α-1C autoantibody-postive SSc patients than that in anti-tubulin-α-1C autoantibody negative group(71.4% vs. 37.5%, P=0.039). The proportions of anti-Scl-70 antibody, anti-CENP antibody and anti-cardiolipin antibody were higher in the group of anti-tubulin-α-1C autoantibody-postive SSc patients than in the anti-tubulin-α-1C autoantibody negative group (37.9% vs. 15.2%, 34.5% vs. 12.1%, 13.8 vs. 0, respectively, all P < 0.05). CONCLUSION Based on this explorative stu-dy, the level of anti-tubulin-α-1C antibody increased in the serum of the patients with SSc. There were correlations between anti-tubulin-α-1C autoantibody and clinical and laboratory indicators of the SSc patients. It may become a novel biomarker indicative of active SSc and could be applied in future clinical practice.

AIMTo determine the deletion junctions of infertile men in Taiwan with azoospermia factor region c (AZFc) deletions and to evaluate the genotype/phenotype correlation.

METHODSGenomic DNAs from 460 infertile men were examined. Bacterial artificial chromosome clones were used to verify the accuracy of polymerase chain reaction. Deletion junctions of the AZFc region were determined by analysis of sequence-tagged sites and gene-specific markers.

RESULTSComplete AZFc deletions, including BPY2, CDY1 and DAZ genes, were identified in 24 men. The proximal breakpoints were clustered between sY1197 and sY1192, and the distal breakpoints were clustered between sY1054 and sY1125 in all but one of the 24 men. The testicular phenotypes of men with complete AZFc deletion varied from oligozoospermia, to hypospermatogenesis, to maturation arrest.

CONCLUSIONWe identified a group of infertile men with uniform deletion junctions of AZFc in the Taiwan population. Despite this homogeneous genetic defect in the AZFc region, no clear genotype/phenotype correlation could be demonstrated.

OBJECTIVETo evaluate the effect of low frequency and high frequency tympanometry in the diagnosis of middle ear function of infants.

METHODSTympanometries with 226 Hz, 678 Hz and 1000 Hz probe tones were obtained from infants aged 5-25 weeks with normal ABR (15 infants, 30 ears) and those with prolonged Wave I latency suggesting middle ear dysfunction (17 infants, 20 ears) using GSI Tympstar middle ear analyzer.

RESULTSThe type, peak pressure, peak compensated static acoustic admittance and gradient of 226 Hz tympanometry were of no significant differences between two groups. The pattern of 678 Hz tympanograms for admittance, susceptance and conductance included non-peaked, single-peaked, W-shaped and three-peaked type in both groups. The consistency between auditory brainstem response (ABR) and 678Hz tympanometry for admittance, susceptance and conductance were 70.0%, 58.0%, 64.0% (kappa = 0. 324,0. 234,0. 118) respectively. A single peaked tympanogram was typical in normal infants for 1000 Hz admittance, susceptance and conductance tympanograms and there were 28 ears (93.3%), 25 ears (83.3%) and 26 (86.7%) respectively. Tympanogram without any positive peak was the most characteristic for a probe frequency of 1000 Hz in infants with prolonged wave I latency and there were 15 ears (75%), 17 ears (85%) and 13 ears (65%) respectively. For admittance, susceptance and conductance, the consistency between 1000 Hz tympanometry and ABR were 90.0%, 92.0% and 86.0% and kappa were 0.783, 0.831 and 0.690, respectively.

CONCLUSIONS1000 Hz probe tone tympanometry was accurate diagnostic tests for middle ear function in infants younger than 25 weeks of age, while 226 Hz and 678 Hz probe tone tympanometries were not.
