Objective The prevalence rate of type 2 diabetes mellitus in schizophrenia patients were significantly higher than normal people.The study examined the glucose metabolism in first-episode, drug-naive patients with schizophrenia. Methods Case-control study was employed.According to the 4th edition of American Diagnostic and Statistical Manual of Mental Disorders, 58 first-episode, drug-naive patients with schizophrenia hospitalized in our hospital were collected for the study.Brief psychiatric rating scale, Hamilton depressive scale and assessment of abnormal involuntary movement were used to assess the mental state and the degree of illness.Meanwhile, 60 hospitalized Han patients in the Second Hospital of Lanzhou University were selected as the control group. Fast plasma glucose (FPG) were detected in the morning on each patient along with oral glucose tolerance test (OGTT).Measure-ments were also made on height, body weight, waist circumference, hip circumference, as well as WHR and body mass index (BMI). Results No significant difference was found in gender, age, diet habit, activity, BMI and the number of education years between the groups(P>0.05).The average FPG of the patient group was higher than that of the control group(5.29 ±0.83 mmol/L vs 4.37 ±0.54 mmol/L);postprandial 2 hour glucose of the patient group was significantly higher than that of the control group ( 6.89 ±0.98 ) mmol/L vs 5.97 ±0.82 mmol/L, P<0.05).Statistical difference in the incidence of impaired glucose tolerance( IGT) was found between the two groups, 8 paitents in patient group(13.8%), 2 in control group(3.3%) (χ2 =4.25,P<0.05).Patients with normal and ab-normal glucose tolerance showed no difference in mental state and illness degree(P>0.05). Conclusions First-episode, drug-na-ive patients with schizophrenia have more impaired fasting glucose tolerance than normal people.In order to identify and intervene the abnormal glucose metabolism of schizophrenia patients, it is of great importance to measure relation index to glucose metabolism, espe-cially the oral glucose tolerance test.

Objective: To summarize the different cardiac shunt presentation in right heart contrast echocardiography and to clarify its clinical value for diagnosing the patients with congenital heart disease (CHD).
Methods: We retrospectively analyzed 102 patients who received right heart contrast echocardiography in our hospital from 2006 to 2014. The contrast media was the hand-vibrated mixture of 9 ml 50% glucose solution with 1 ml air.
Results: There were 49/102 patients with abnormal blood shunt detected including 8 patients of atrial septal defect (ASD) with right to left or dual shunt, 7 of ASD with left to right shunt, 9 of patent foramen ovale (PFO) with functional right to left shunt, 13 of patent ductus arteriosus (PDA) combining pulmonary arterial hypertension, 3 of pulmonary arteriovenous ifstula (PAVF), 9 patients with persistent left superior vena cava (PLSVC) and 8 of them drain to coronary vein sinus, 1 drain to left atrium.
Conclusion: Right heart contrast echocardiography may simply and effectively detect abnormal blood shunt in patients combining pulmonary arterial hypertension and improve the diagnostic accuracy of CHD.

Objective To study the serum HBV cccDNA and genotype of hepatitis B virus in children in Gansu province.Methods 124 HBV-DNA positive children were randomly selected,with 84 males and 40 females.Among the 124 patients,65 were HBV carriers,59 were chronic hepatitis(31 mild,18 moderate and 10 severe).Genotypes of their serum HBV,liver function,HBV-DNA load and serum HBV cccDNA were detected.Results In the moderate and severe groups,HBV cccDNA positive rate was higher than that in the HBV carriers or the mild group(F=25.429,P＜0.01).The HBV cccDNA detection rate in HBeAg positive group was higher than that in the HBeAg negative group(F=28.386,P＜0.01).In the HBV cccDNA positive group,glutamic-pyruvic transaminase,glutamic-oxaloacetic transaminase,total bilirubin were higher than that in the negative group(t respectively 13.241,11.347,15.013,P＜0.01).Both C and B genotypes appeared to be the majority while C genotype was dominant in the 124 cases of children hepatitis,with the rest as B/C and some other genotypes.The positive rate of HBV cccDNA C genotype was higher than that of the genotype B(F=23.216,P＜0.01)and the negative rate of HBV cccDNA genotype was higher than that of the C genotype(F=26.364,P＜0.01).Conclusion Higher detection rate was found inthose more severe cases in the peripheral blood streams.HBV cccDNA and genotype testing might better reflect the level of HBV replication and the clinical severity of the disease,showing its guiding role in clinical diagnosis and treatment of hepatitis B.

OBJECTIVETo prepare monoclonal antibodies (mAbs) against enoyl-CoA hydratase 1 (ECH1).

METHODSNormal human liver tissues were homogenized, and the mitochondria were isolated by differential centrifugation. The total mitochondrial proteins were used to immunize BALB/c mice to prepare mAbs by routine hybridoma technique. The mAbs were characterized by ELISA, Western blotting and immunohistochemistry. The specificity of the antibody was identified by mass spectrometry (MS) following immunoprecipitation (IP) and confirmed by Uni-ZAP expression library screening.

RESULTSOne clone of the hybridoma BGB095 secreting specific mAb against ECH1 was obtained. The mAb was identified to belong to Ig subclass IgG1 and could be used in ELISA, Western blotting, immunohistochemistry, and immunoprecipitation.

CONCLUSIONA hybridoma cell line stably secreting specific mAb against ECH1 has been established. The specific mAb against ECH1 can be of great value for functional and distribution studies of ECH1.

It has been demonstrated that activated carbon supported tungstosilicic acid is an excellent catalyst. Various factors involved in these reactions were investigated. The optimum conditions found were: molar ratio of aldehyde/ketone to glycol is 1/1.5, mass ratio of the catalyst used to the reactants is 1.0%, and reaction time is 1.0 h. Under these conditions, the yield of 2-methyl-2-ethoxycarbonylmethyl-1,3-dioxolane is 61.5%, of 2,4-dimethyl- 2-ethoxycarbonylmethyl-1,3-dioxolane is 69.1%, of cyclohexanone ethylene ketal is 74.6%, of cyclohexanone 1,2-propanediol ketal is 80.1%, of butanone ethylene ketal is 69.5%, of butanone 1,2-propanediol ketal is 78.5%, of 2-phenyl-1,3-dioxolane is 56.7%, of 4-methyl-2-phenyl-1,3-dioxolane is 86.2%, of 2-propyl-1,3-dioxolane is 87.5%, of 4-methyl-2-propyl-1,3-dioxolane is 87.9%.

OBJECTIVETo investigate the relationship between genotype of hepatitis B virus and hepatitis B virus related-glomerular nephritis in (HBV-GN) children.

METHODTotally 176 HBV-DNA positive children with chronic hepatitis B were randomly collected. Among the 176 patients, 92 were HBV carriers, 84 were cases with chronic hepatitis. The genotypes of their serum HBV, liver function, and HBV-DNA load were detected. When children showed nephrotic syndrome, renal biopsy was performed.

RESULTOf the serum samples of 176 cases, 85 (48.3%) were genotype C, 72 (40.9%) were genotype B, 13 (7.4%) were genotype B/C, and 6 (3.4%) were non-B/C genotype which were excluded. Among the analyzed 157 cases, the ratio of HBV-GN in the HBeAg positive group (78.3%) was significantly higher than that in the negative group (21.7%) (χ(2) = 18.301, P < 0.001). And, the ratio of HBV-GN in the genotype C group (73.9%) was significantly higher than that in the genotype B group (26.1%) (P < 0.039). The ratio of hematuria or proteinuria in the genotype C group (20%, 18.8%) was significantly higher than that in the genotype B group (8.3%, 5.6%) (P < 0.039; P value = 0.013); and the alteration of ALT or C3 in the genotype C group (10.2%, 15.3%) was more frequent than those in the genotype B group (2.8%, 2.8%) (P = 0.005; P = 0.008). There were no significant differences in kidney dysfunction or hepatomegaly. Further, the ratio of HBV-GN was more significantly frequent in HBV-DNA highly loading group (79.2%) than which in HBV-DNA lowly loading group (20.8%) (P = 0.000). Finally, in HBV-GN group, genotype C cases (88.2%) more frequently had high HBV-DNA load condition than genotype B cases (11.8%) (P = 0.021).

CONCLUSIONChildren with HBV infection in Gansu province showed mainly genotypes C or B, while genotype C seemingly predominant. Patients with genotype C more frequently showed proteinuria or hematuria. The high HBV-DNA load may be related with HBV-GN. It is a potential reason in the mechanism of HBV-GN that patients with genotype C had more possibility to have HBV-DNA high load. Analysis of HBV genotype for HBV patients maybe helpful in diagnosis and treatment.

BACKGROUNDThe prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL.

METHODSOne hundred and thirty-six CSSNHL patients treated in Department of Otolaryngology-Head and Neck Surgery and Institute of Otolaryngology at Chinese PLA General Hospital between July 2008 and August 2015 were included in this study. These patients were analyzed for clinical characteristics, audiological characteristics, laboratory examinations, and prognostic factors.

RESULTSAmong the 136 patients (151 ears), 121 patients (121 ears, 80.1%) were diagnosed with unilaterally CSSNHL, and 15 patients (30 ears, 19.9%) with bilateral CSSNHL. The complete recovery rate of CSSNHL was 9.3%, and the overall recovery rate was 37.7%. We found that initial degree of hearing loss, onset of treatment, tinnitus, the ascending type audiogram, gender, side of hearing loss, the recorded auditory brainstem response (ABR), and distortion product otoacoustic emissions (DPOAEs) had prognostic significance. Age, ear fullness, and vertigo had no significant correlation with recovery. Furthermore, the relevant blood tests showed 30.8% of the children had abnormal white blood cell (WBC) counts, 22.1% had elevated homocysteine levels, 65.8% had high alkaline phosphatase (ALP), 33.8% had high IgE antibody levels, and 86.1% had positive cytomegalovirus (CMV) IgG antibodies.

CONCLUSIONSCSSNHL commonly occurs unilaterally and results in severe hearing loss. Initial severe hearing loss and bilateral hearing loss are negative prognostic factors for hearing recovery, while positive prognostic factors include tinnitus, gender, the ascending type audiogram, early treatment, identifiable ABR waves, and DPOAEs. Age, vertigo, and ear fullness are not correlated with the recovery. Some serologic indicators, including the level of WBC, platelet, homocysteine, ALP, positive CMV IgG antibody, fibrinogen, and some immunologic indicators, are closely related to CSSNHL.

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 effects of vitamin-mineral supplement on young males with physical overtraining.

METHODSTwo hundred and forty male Chinese field artillery personnel who undertook large scale and endurance military training and were on ordinary Chinese diet were randomized to receive a multivitamin/multimineral supplement or a placebo for 1 week. After a 1-week wash-out period, a cross-over with 1 week course of a placebo or multivitamin/multimineral supplement was conducted. Blood and urine samples were analyzed for adrenal, gonadal and thyroid hormones. In addition, cellular immune parameters (CD3+, CD3+CD4+, CD3+CD8+, CD4/CD8, CD3-CD56+, CD3-CD19+) were examined and psychological tests were performed before and after the training program and nutrition intervention.

RESULTSAfter a large scale and endurance military training, the participants showed significantly increased thyroid function, decreased adrenal cortex, testosterone and immunological function, and significantly increased somatization, anger and tension. Compared to placebo, multivitamin/ multimineral intervention showed significant effects on functional recovery of the pituitary - adrenal axis, pituitary-gonadal axis, pituitary- thyroid axis and immune system as well as psychological parameters.

CONCLUSIONHigh-intensity military operations have significant impacts on the psychology, physical ability and neuroendocrine-immune system in young males. Appropriate supplementation of multivitamin/multimineral can facilitate the recovery of the psychology, physical ability and neuroendocrine-immune system in young males who take ordinary Chinese diet.
