T mutation was detected in the 4th propositus at the 9th intron,but any COL1A1 or COL1A2 gene mutation was detected in the third propositus and the other members in the former families.Conclusions The genetic mutation of COL1A1 may result in OI in China,but other mutations may also exist.Moreover,the phenotype was influenced not only by OI genotype,but also by the genetic background,environment and other factors.

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

ObjectiveTo evaluate the effects caused by different doses of N-nitrosodiethylamine (DENA) on establishment of a multistep carcinogenesis model of liver cirrhosis in SD rats.MethodsFifty male SD rats were randomly divided into control group (n =5 ) and experimental group (n =45 ).Experimental group consisted of 3subgroups(high,median and low dosegroup ),which were intragastrically induced DENA once a week for 10 weeks,by using 70,50,35 mg/kg DENA solution,respectively.MRI was performed for inspecting pathological changes of rat livers in the following weeks.The mortality rates of different groups were calculated.The differences of the incidence of dysplastic nodule (DN)found in three groups were analyzed with Pearson Chi-square test.ResultsThe multistep carcinogenesis development from regenerative nodule (RN) to DN to hepatocellular carcinoma (HCC) was showed in the SD rat model.Two rats in median dose group and 4 rats in high dose group died.The incidence of DNs found in 3 different groups was 20.7％ ( 6/29 ),30.6％ ( 19/62 ),14.3％ (9/63),respectively,which showed no significant difference among three groups(x2 =4.901,P ＞ 0.05).However,significant difference existed between median and high dose group( x2 =4.811,P ＜ 0.05 ).Combined with the MRI presentation,the intragastric dose of 50 mg/kg could be more appropriate among three different doses.ConclusionsThe median dose DENA could induce an ideal multistep carcinogenesis model of HCC which is suitable for investigating DN on MRI.

Objective　To analyze the effects of flexible ureteroscopic Holmium laser lithotripsy on renal function in the treatmen of renal calculi.　Methods　From October 2010 to March 2012,41 cases of solitary renal calculi (24 males and 17 females) were treated with flexible ureteroscopic Holmium laser lithotripsy ( FURL).Patient's mean age was 51.9 ± 15.9 years ( range from 31 to 88 years).Locations of renal calculi detected by image study were 22 cases in middle and upper calyx,9 cases in lower calyx,10 case in renal pelvis.The mean size of calculi was 16.9 ±6.0 mm (range from 10 to 28 mm).Blood samples (2 h pre-operatively,and then 2 h,12 h,24 h,48 h,72 h post-operatively) were collected and serum　NGAL,serum Cys-C were tested　Results　The measured levels of pre-operative NGAL and Cys-C were 3.5 ± 0.6μg/L,501.7±121.3 μg/L,and levels of post-operative NGAL at 2 h,12 h,24 h,48 h and 72 h were 4.2±0.8 μg/L,5.0±1.0 μg/L,4.9±1.4 μg/L,4.3± 1.1 μg/L and 3.8 ±0.1 μg/L,while the according levels of Cys-C were ( 516.4 ± 126.2 ) μg/L,( 723.8 ± 134.8 ) μg/L,( 770.4 ± 162.8 ) μg/L,(671.7 ± 138.3 ) μg/L and 574.0 ± 116.7 μg/L.Serum NGAL began to increase 2 hours after operation (P ＜0.05,and reached the peak in 12 hours,it began to decline 12 hours after surgery,but it was still higher at 72 hours than pre-operative level (P ＜ 0.05.Serum Cys-C showed no obvious ascent 2 hours after operation in FURL group ( P ＞ 0.05 ),but increased obviously 12 hours after operation and lowered down after the peak that occurred 24 hours after surgery.Serum Cys-C still remain above the baseline 72 hours after operation (P ＜0.05).　Conclusions　Flexible ureteroscope lithotripsy can cause reversible damage to renal function after surgery.

Objective To investigate the associations of variants in signal transducer and activator of transcription 4 (STAT4) in Chinese Han population with rheumatoid arthritis (RA). Methods The study was performed in 228 RA cases and 228 controls. Haplotypes from the HapMap database Chinese population were used to select tag-single-nucleotide polymorphisms (SNPs) (r2=0.9) in STAT4 gene. Twenty-three SNPs located in STAT4 gene were examined by multiplex polymerase chain reaction (PCR) and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS). The Hardy-Weinberg equilibrium (HWE) was tested by a chi-square and Fisherˊs analysis. Differences in genotypes of the STAT4 polymorphism variants were evaluated using a Chi-square test. All statistical analyses were done with Haploview 4.1 software. Results Significant difference was detected in three SNPs (rs11685878, rs129888 and rs16833437) in allele frequencies analysis (χ2=6.014 8, 4.024 8, 5.539 1, P<0.05). Association was detected for three SNPs (rs11685878, rs16833437 and rs12988825) in genotype analysis ( χ2=6.814 9, 6.098 7, 6.691 7, P<0.05). Conclusion STAT4 may associate with susceptibility in Chinese Han population.

OBJECTIVETo investigate the gene mutation in the areas of pre core/core (Pre C/C) and basic core promotor (BCP) of HBV DNA and its clinical significance.

METHODSThe nt 1 735-1 965 segment of HBV DNA was amplified with PCR in 54 cases with chronic hepatitis B and 10 cases with post-hepatitis cirrhosis. Then the PCR product was sequenced.

RESULTSThere were 168 site mutations in 48.5% (33/68) cases with hepatitis B. The first ten mutation sites were nt 1 764 (58.8%), 1 762 (48.5%), 1 799 (21.0%), 1 766 (14.7%), 1 896 (13.2%), 1 754 (8.8%), 1 899 (8.8%), 1 768 (7.4%), 1 814 (7.4%) and 1 913 (7.4%). Three rare mutations of nt 1907, 1 922 and 1 923 were also detected. The mutations of nt 1 896, 1 764 and 1 762 were found in 16.7%, 35.2% and 35.2% of chronic hepatitis, and in 30.0%, 60.0% and 60.0% respectively of post-hepatitis cirrhosis cases. There was statistical significance between the two groups (P < 0.01).

CONCLUSIONThe mutations in the areas of Pre C/C and BCP of HBV DNA might possibly be associated with liver fibrosis. There are many mutation sites in HBV DNA and mutation occurs frequently, therefore gene sequencing is helpful to the design of gene chip and to clinical application.

OBJECTIVE: To investigate whether there are autoantibodies to nasopharyngeal carcinoma (NPC) in the sera of patients and to find new NPC biomarkers. METHODS: Cell plate of Epstein Barr virus negative NPC cell line CNE1 was prepared, and difference between 32 NPC patient sera and 54 normal sera was analyzed by ELISA. We extracted the total protein of CNE1, and analyzed whether there were specific proteins to react with NPC sera by Western blot. RESULTS: The average absorbance values of serum antibody in NPC patients (0.904+/-0.032) were significantly higher than those of normal serum antibody absorbance values (0.736+/-0.028) (P< 0.01). The analysis with Western blot showed there were positive bands,and some of these were unanimous bands, but the intensity increased, and some of these were new bands compared with the normal sera. These positive bands may be NPC tumor-associated antigens or NPC tumor-specific antigens. CONCLUSION Autoantibodies that react with NPC exist in the sera of NPC patients, but they do not react with Epstein-Barr virus. It provides the basis to seek the tumor biomarkers in NPC sera.

OBJECTIVETo confirm the effect of Er'bao granule (EBG) on the sensitivity to peripheral afferent signal of neurons in lateral hypothalamic area (LHA) to illustrate the central mechanism of EBG in promoting ingestion behavior.

METHODSThe anorexia rat model was established by feeding special prepared forage for one week, and all the model rats were administrated with EBG by gavage for 3 weeks. The spontaneous discharge of LHA neurons was recorded using electro-physiological extracellular recording method, and its response to electrical stimulus on gastric vagus nerve and intravenous injection of glucose were observed and compared among the normal, model and treated groups.

RESULTSAs compared with the normal group, among the LHA neurons responding to afferent gastric vagal impulse, the proportion of glycemia-sensitive neurons in the model group was significantly decreased (P <0.01), but insignificant difference was shown in comparison between the treated group and the normal group.

CONCLUSIONEBG play a role in regulating the sensitivity of LHA neurons to peripheral afferent signal and thus to influence the multi-afferent information integration of ingestion central neurons.
