Objective To explore the potential association between HLA-DRB1 Alleles and systemic scleroderma (SSc) of the Zhuang Nationality in Guangxi region. Methods Polymerase chain reaction-special sequence primers (PCR-SSP) was used to study the HLA-DRB1 alleles in 58 patients with SSc and 50 healthy controls of the Zhuang Nationalty in Guangxi Province. Comparisons between groups were performed with χ2 test or exact probabilities. Results Sixteen HLA-DRB1 alleles were discovered from the specimens,including 14 in the SSc specimens, and 16 in the control specimens. Among them,the allele frequencies of HLA-DRB1 * 1301 (7.760%, OR=9.000, χ2=4.341, P=0.037), HLA-DRB1 * 1305 (11.207%, OR=3.322,χ2=4.206, P=0.040) and DRB1 * 15 (26.724%, OR=2.679, χ2=6.038, P=0.014) were significantly higher in SSc patients than those of the controls (respectively for 1.000%, 4.000%, 15.000%). Conclusion Our data suggest that the HLA-DRB1 * 1301, HLA-DRB1 * 1305 and HLA-DRB1 * 15 may be the susceptible genes of SSc in Zhuang nationality population.

Objective To investigate the relationship between diabetic retinopathy(DR) and the state of diabetes mellitus(DM) control.Methods The factors for the occurrence and development of DR were analyzed by non conditional Logistic regression model.Results 5 significant factors were screened out,which were urinary microalbumin excretion index(ALB/Cr),blood glucose before breakfast,glycosylated hemoglobin(HbAlc),diabetic neuropathy and course of DM.And the sugestible threshold value of blood glucose before breakfast is 7.90mmol/L at which we can prevent the occurrence of DR,and at 7.15mmol/L,occurrence of DR can be strictly controlled.Conclusion The state of controlling blood glucose and other complications in DM patients influences the occurrence and development of DR.

Objective To study the anti-inflammation mechanism of Jinzhuyalong Ershiwuwei coral capsule on cervical spondylosis by investigating Jinzhuyalong Ershiwuwei coral capsule on PLA2 in degenerated cervical intervertebral discs.Methods 60SD rats (SPF) were divided into a control group (15),a medicine model control group (15),a medicine modle 1 group (15),and a medicine model 2 group (15) by random lottery; Medicine model 1,2 groups were given Jinzhuyalong Ershiwuwei coral capsule powder 0.33 × 5 g/kg 0.66×5 g/kg,and added 1 ml distilled water dilution lavage,l/d,90 d,The unbalance of power cervical spondylosis animal models were chosen and C4～5 neck intervertebral discs were taken after 90 days.Millipore colorimetry methods were used to measure PLA2 activity in C4～5 cervical intervertebral discs.Results The PLA2 activity of the cervical intervertebral disc (12.37 ± 4.21) IU/mg · min-1 in the model group was significantly higher than the control group(2.56± 1.19)IU/mg· min-1 (P＜0.05).The cervical intervertebral disc PLA2 activity of medicine model group 1 (8.56± 2.13)IU/mg · min-1 and medicine model group 2 (5.58 ±2.39)IU/mg· min-1 was lower than the model control group(12.37±4.21)IU/mg· min-1,with significant differences (both P＜0.01).Conclusion Jinzhuyalong Ershiwuwei coral capsule could down regulate PLA2 activity in degenerated cervical intervertebral discs,and also decrease the production of some inflammaroty mediators.

Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

Objective To analyze the ABCD1 gene mutations in 5 cases of X-linked adrenoleukodystrophy(X-ALD) patients and 2 cases of their mothers.Methods Of 5 patients with X-ALD,10 exons and flanking intronic sequences of ABCD1 gene were amplified by polyme-rase chain reaction,and then sequenced directly.The outcomes were compared with normal ABCD1 sequencings to identify the mutation type and site.Thirty normal men were examined in the mean time as control for the confirmation of mutations and gene polymorphisms.Results Three patients showed ABCD1 gene mutations,1 had a point mutation in exon 6,Arg518Gly(CGG→GGG);2 patients showed the same novel mutation in exon 1 with 8 bases deletion(134del8).Four gene polymorphisms were identified in exon 7.They were Gly551X(GGC→GGT),Arg554His(CGT→CAT),Gln567Arg(CAA→CGA) and Val582Ile(GTC→ATC).ABCD1 gene mutation was not found in 2 mothers from 2 unrelated fa-milies with X-ALD.Conclusions Three cases of 5 were detected for ABCD1 gene mutations.Between them,the 134del8 mutation is a novel one.Four new gene polymorphisms were detected in exon 7 in normal Chinese people,which were Gly551X,Arg554His,Gln567Arg and Val582Ile.

Objective To analyze effect of balloon embolization therapy for traumatic carotid cavernous fistula (TCCF),so as to provide references for treatment of this disease.Methods A total of 21 patients with TCCF managed with balloon embolization from April 2006 to March 2012 were collected in the study.There were 17 males aged (32.3 ±5.4) years and 4 females aged (40.6 ±5.8)years.Perioperative clinical presentations and imageologic changes were observed as well as operative outcome was evaluated.Results After 3 months of follow-up,20 patients experienced successful detachable balloon embolization,but the other one patient had to have stent angioplasty due to the failure of the procedure.All patients had some improvements on clinical presentations after operation (P ＜ 0.05).Imageologic examination revealed that all patients had complete occlusion of TCCF following operation.In follow-up,one patient had a relapse,with total curative ratio of 95％.Conclusions Detachable balloon embolization is effective in treatment of TCCF.Presently,the technique is an optimal method for such kind of disease and is worthy of wide clinical use.

Objective To design a monitoring system of the state of life for a crew in order to ensure their life safety. Methods A wearable physiological parameter monitoring technology was used, and the fabric electrode and temperature sensors were embedded in the vest.The thress-lead electrode was used to extract ECG and respiration signal,temperature signals were collected with a thermistor of negative temperature parameters.Blood pressure and blood oxygen saturation were detected by a finger cuff type of blood oxygen sensors.The volume pulse wave velocity method was used to extract blood pressure signals,and the photoelectric measurement method was used to extract blood oxygen saturation signals.The state of life was evaluated by calculation of the times of respiration and divided into 4 states.Results and Conclusion The system is capable of low load dynamic monitoring of physiological parameters of a crew and evaluation of their state of life, contributing much to self-aid and buddy aid among the crew.
